Venus' rotation does which of the following?
A. Its year lasts 225 days and its day is 243. This is the second question of yours i've answered, and it makes me sad because i think it's a shame you aren't more enthusiastic about astronomy. How have you ended up being set questions in this subject if you don't enjoy it? However, i do think it has a great deal of appeal and i suggest you look into it more. It's just amazing. Apart from anything else, no matter what's going on in your life or on this planet, the Universe is so much bigger and more wonderful than that, and you can sit in a gutter and look at the stars, as Oscar Wilde once said. Sorry to have a go, it's just that i feel so passionate about astronomy that i think you're really missing out.
How long is Venus' Revolution and Rotation?
Orbital period (Time for 1 orbit around Sun): 225 Days Rotational Period: 243 Days Venus spins backward on its axis as compared to the other planets and its day is longer than its year. Thinking is that its rotation was affected/disturbed by an impact sometime in the past.
Venus information please?
-67.2 million miles -Venus is the second planet from the sun. This planet is called the "twin" planet of Earth because they are so similar in size. -None. There are no natural satellites orbiting Venus. The only bodies orbiting it are the ones we have placed there such as NASA's Magellan radar satellite which produced the above picture of the surface of Venus. -Venus is often referred to as Earth’s twin planet (evil twin planet is more like it, when you consider the scorching temperatures). It’s almost the same size, mass, gravity and overall composition. The composition of Venus is pretty similar to Earth, with a core of metal, a mantle of liquid rock, and an outer crust of solid rock. -It's diameter is about 7,520 miles (12,100 kilometers) -two artificial satellites (space probes). Venus is one of the two planets in our solar system (together with Mercury) that have no moon/natural satellite. Hope i helped :)
How can the period of rotation of Venus be decreased?
We need to be a little more specific here with the numbers:117 days is the solar day not sidereal day. The sidereal day on Venus is actually much longer - it is equivalent to about 243 days on Earth.So, what that really means is that Venus actually takes 243 days to do a 360 degree rotation. However, since Venus has a retrograde rotation with respect to its orbit, the time it takes for the Sun to rise, set, and rise again is actually shorter - the 117 days you mention.Interestingly enough, earlier this year, ESA's Venus Express spacecraft studied Venus and determined that the sidereal day has actually decreased by 6.5 Earth minutes since NASA's Magellan spacecraft was there, 16 years ago. Although that sounds like a small change (Venus' rotation now takes 349948.1 Earth minutes instead of 349941.6 minutes) it actually is a very dramatic change that has scientists puzzled.One theory is that the deceleration was caused by weather. The atmosphere on Venus is 90 times denser than ours on Earth. Scientists believe that the friction between an active weather system and the planet's surface might have actually caused the planet to slow down.So, a theoretical answer to your question would be to engender such violent weather that we can create a friction force and use that force to manipulate the speed of the surface. I put an emphasis on "theoretical answer" because I have no idea how we could actually put such a plan into effect.
What is the axis of rotation of planets?
Axis of rotation of the planets - EARTH - inclination = 23.5º, rotation period = 24 hours MARS - inclination = 24º, rotation period = 24.6 hours VENUS - inclination = 3º , rotation period = 243 days http://hyperphysics.phy-astr.gsu.edu/hba... "...What is different about Venus’s rotation compared to the other planets you observed..." Check the rotation periods listed above "...Which planet has no seasons? Explain..." Venus. The super-dense atmosphere of Venus causes its *global* surface temperature to remain constant, thus no seasons. "...Which planet has similars most similar to Earth? Explain..." Pretty ambiguous question. It could be Venus because its mass and size is very close to that of Earth. Could be Mars because its rotational period and inclination are almost the same as Earth, and it lies (just barely) within the habitable zone of our sun.
Rotation period.?
Any ball of rock or gas can rotate at darn near any period you want, for instance, giant Jupiter rotates about once every 12 hours, and dinky Mercury rotates once every 115 days. If the ball is too small or the rotation is too fast it could break up (and before that flatten out into a disk noticibly). Just balance centripetal acceleration against gravity to find this breakup speed. v^2/r <= GM/r^2 where G is the gravitational constant (which you can look up online) and M is the total mass, v is the velocity of the rotation and r is the radius of the ball. Rotational velocity V = 2*PI*r/P where P is period. You can combine those to get Keplers law except r is the radius of the orbit now. (yeah, essentially the planets orbit the sun at breakup velocity, which is why they are not PART of the Sun.) Keplers law is what you need to use if you are interested in the orbital periods of the planets. The mass you use in all cases is the total mass of the system, though in the case of planets around a star you can generally ignore everything but the star.
How long are the periods of rotation and revolution on Venus?
VenusSimilar in structure and size to Earth, Venus' thick, toxic atmosphere traps heat in a runaway greenhouse effect. A permanent layer of clouds traps heat, creating surface temperatures hot enough to melt lead. Glimpses below the clouds reveal volcanoes and deformed mountains. Venus spins slowly in the opposite direction of most planets.Venus: 10 Need-To-Know ThingsEarth-SizedVenus is only a little smaller than Earth. If the sun were as tall as a typical front door, the Earth and Venus would each be about the size of a nickel.Second RockVenus orbits our sun, a star. Venus is the second closest planet to the sun at a distance of about 108 million km (67 million miles) or 0.72 AU.A Day Longer Than a YearOne day on Venus lasts as long as 243 Earth days (the time it takes for Venus to rotate or spin once). Venus makes a complete orbit around the sun (a year in Venusian time) in 225 Earth days.Rough TerrainVenus is a rocky planet, also known as a terrestrial planet. Venus' solid surface is a cratered and volcanic landscape.Always CloudyVenus' thick and toxic atmosphere is made up mostly of carbon dioxide (CO2) and nitrogen (N2), with clouds of sulfuric acid (H2SO4) droplets.MoonlessVenus has no moons.RinglessThere are no rings around Venus.Many VisitorsMore than 40 spacecraft have explored Venus. The Magellan mission in the early 1990s mapped 98 percent of the planet's surface.No Place to LiveNo evidence for life has been found on Venus. The planet's extreme high temperatures of almost 480 degrees Celsius (900 degrees Fahrenheit) make it seem an unlikely place for for life as we know it.BackspinVenus spins backwards (retrograde rotation) when compared to the other planets. This means that the sun rises in the west and sets in the east on Venus.NASA app
Why is Venus's rotation so much different than the Earth and Mars?
Firstly, I’d like to point out that I am no means an expert in planetary mechanics, but since you asked….The planet Venus is similar to Earth, but polar opposite at the same time. It is roughly the same size and mass, but around there is where the similarity ends.It’s atmospheric composition is far more volatile and toxic compared to Earth, while the surface is hellish like.In terms of why the planet’s rotation is dissimilar to Earth, has a lot of complexity behind it, although it is possible that the planet was struck by another planet/asteroid like object during the early stages of the planet's formation, shifting its angular momentum. Quite similar to what happened to Earth which resulted in the formation of the moon.Furthermore, the internal composition of Venus may have a part to play with regards to its rotation.Hope this helps.EDIT 1: Venus has been the most amazing amongst the solar members.There are so many mind blowing facts about it,such as:1:VENUS COMPLETES IT’S REVOLUTION EARLIER THAN IT’S ROTATION!!!!Sounds strange but it is true.The reason behind this was a catastrophic collision that took over millions of year ago.Actually at the time of development of the planets of our solar family,earth and venus were almost similar to each other in all the aspects such as size,mass,atmosphere and the direction of spin too.But because of the collision of venus with a fragment of space debris,venus STOPPED awhile and then started rotating in opposite direction!!!!!And in turn,,the rotation speed of the venus was lowered upto such a extent that it completes IT’S REVOLUTION EARLIER THAN IT’S ROTATION!!!2:THE ATMOSPHERIC PRESSURE ON VENUS IS SO HIGH THAT IT CAN CRUSH A “CAR”WITHIN NO TIME!!!YESSS!!! Don’t think to do this.This is due to the fact that the sun rays,water vapours,volcanic gases etc are continuously accumulating in the atmosphere of venus which in turn making the atmosphere denser and more denser,and due this the atm. Pressure of venus has increased to such a dangerous level||||||
Would it be possible to increase the speed of rotation of Venus, giving it a 24 hour day?
You mean, how many high-energy low-inclination asteroid impacts would it take to adjust Venus’ rotational period to match Earth’s? Probably intending to begin your terraforming this way?It depends on how massive those asteroids were… but without even beginning the math, I can tell you the answer is “Too many.” Such a massive and sustained high-energy bombardment of the planet would so badly damage it that by the time you succeeded in getting the rotational period roughly where you wanted it, Venus would be a seething volcanic mess, geologically unstable and useless for the next X million years while it cooled down and its crust re-formed.Keep in mind that one “day” on Venus takes 118 Earth-days… you want to multiply that spin speed by a factor of 118, and this is a planet we’re talking about. You want to change that spin speed by pelting it with relatively tiny asteroids, albeit a magically unlimited number, magically delivered at the most effective possible speed and trajectory, and huge volleys of these asteroids at a time so that together, over a sustained bombardment period, they add up to a force sufficient to achieve your goal.Imagine shooting tiny BBs at a Toyota Yaris that’s resting on a frictionless surface, and shooting so many BBs at a time, at such a high speed, and maintaining a high rate of fire for such a long time that you get that Yaris spinning like a top. It won’t look like a Yaris anymore when you’re done, that’s for sure!Just because it’s a Yaris and not a giant mining truck doesn’t mean a handful of BBs are going to affect it much.I’m intrigued now… are you asking this because you’re working on a science fiction story?
Is there a relationship between Venus rotation (retrograde) and her revolution around the sun?
The Matter is a RATE between 2 values and no matter is independentThe motion is relative and no meaning for absolute motionSoLet’s provide some new ideas to extend our thinkingCopernicus-Kepler Model Modification:1-The sun is on the vertical level relative to the Earth.2All solar planets are found on the horizontal level relative to the Earth3The Sun is higher than the Earth, and higher than all solar planets4The straight line from the Sun to the Earth is the main line in the solar group5The planets revolve around this line, and not around the sun herself..6i.e. the Planets revolve around the line connected between the Sun and the Earth…7-That means when the planet revolve around the sun, he will revolve around the Earth also because both of them connected by this same one line8th-That's why, the Ptolemy model lived very long time, because it was correct9-So if the planet revolve around the sun or around the Earth the result will be the same, because both of them contributed to create the main line in the solar group10-And because the sun is higher than the Earth, we see the sun hesitating motion to forward and backward with angle 63.7 degrees yearly, as a circle motion11-So the sun circle motion is NOT true, but resulted from our wrong vision for the sun motion…12-I claim, the planets from the Earth to Pluto move toward the sun, but Mercury and Venus move in the reverse direction13-The Earth daily displacement toward the sun = 1 km14-The previous modification can give us some explanation for the Egyptian astronomical phenomenon 2737, in which Mercury, Venus and Saturn were perpendicular on the Earth on 3/12/2012(on the Egyptian pyramids heads-appendix No.1),15Which proves, that the planets Not only revolve around the sun but also revolve around the Earth, supports this modification.Please read my paperGerges Francis tawdroushttps://de.slideshare.net/Georgy...
