How is Uranus distance from the Sun calculates in AU?
It is 20x times further than planet earth from the sun
How can we calculate the distance and size of the Sun?
In the early 17th century, Kepler spent a lot of time analyzing observations of the planets by people like Brahe. From from that analysis he determined a mathematical relationship.That is that the period of a planet (time it takes to travel once around the sun) squared is equal to the distance between the sun and that planet, cubed. That is, if the units are years and astronomical units - with an astronomical unit (AU) being the distance between the sun and the Earth. From that relationship he concluded the following distances:Kepler had found the geometric relationships for the distances in the solar system, but he didn't know the scale - he didn't know how far an AU actually was.About half a century later, Cassini figured out a way to figure it out by taking advantage of a concept called parallax.Cassini decided to use parallax to determine the distance to Mars. He had a buddy named Richer agree to observe Mars at the same time as he did, but Richer would do it from French Guiana while Cassini did it from Paris. They would conduct the experiment when Mars was at its closest to Earth, basically putting the Sun, Earth, and Mars on a straight line. They observed something like this:While the extremely far away stars appeared static, Mars, much closer, appeared to be in a slightly different place, because of parallax.Because Cassini knew how far apart he and Richer were, and he knew the angles involved in the observation, he could use trigonometry to determine the distance between the Earth and Mars.That distance is about 78 million kilometers. Kepler told us that the Earth-Mars distance was 0.52 AU.That means that the Sun-Earth distance of 1.0 AU would be about 150 million kilometers.So, now that we have figured out how far away the sun is, figuring out its size is fairly easy. We can measure the angular size of the sun through simple visual observation. If we know that angle and we know the distance from the Earth to the Sun, we can use trigonometry (the Law of Sines) to determine the actual diameter of the Sun (1,391,000 km).
How do you calculate the distance of a planet from the sun using AU?
AU is already a distance. You can convert it into other units. 1AU is roughly 149 million km, or about 93 million miles. Simple multiplication will give you the distance in either. x = distance in AU To convert into km: x * 149,000,000 = distance in km For miles x * 93,000,000 = distance in miles Keep in mind, all planets have orbital eccentricities. The Earth vries from about 147,000,000 km from the Sun to about 151,000,000 km. The 'mean' distance from the Sun, is 1.00 AU, which is 149,597,871 kilometers.
Calculate the average distance of Neptune from the Sun?
The orbital period of the planet Neptune is 164.8 years. Calculate the average distance of Neptune from the Sun. And if you can please give the formula that you used. thanks :)
Using Kepler's third law to determine the distance from the Sun of a planet whose period is 5 years.?
Kepler's Third Law states that the ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun. Here, the "period" simply means the length of time it takes for a planet to orbit the sun once. If R1 and R1 are the orbital radii (i.e., the distance from the sun) of planets 1 and 2, and T1 and T2 are the orbital periods, then the Kepler's Thrd Law has the mathematical form: (T1/T2)^2 = (R1/R2)^3 Here, we know that for the Earth, T1 = 1 year, and R1 = 1 AU (1 AU is one Astronomical Unit, which is defined as the average distance from the Earth to the Sun). We want to find R2 if T2 = 5 years. So: (1 yr /5 yr)^2 = (1 AU/R2)^3 1/25 = (1 AU)^3/(R2)^3 R2 = (25 AU^3)^(1/3) R2 = 2.924 AU
If you knew the distance of a planet from the Sun, explain how you would calculate its period of revolution?
For a first approximation to the orbital period, I would use Kepler's law: P^2 = a^3 where P is the period in Earth years and "a" is the semi-major axis (approximately the average distance) in "astronomical units" where 1 A.U. = distance from Sun to Earth. --- Iridflare is correct. The period of revolution (time to spin around its own internal axis) has little to do with distance to Sun, except for planets very close to the Sun (like Mercury). Given the distance to the Sun, you can calculate the period of "translation" (a.k.a. the orbital period)
How do you calculate the distance in AU(Astronomical Unit)?
Okay, I am not so good at science...and I can't really get a hold of calculating the distance of planets using Astronomical Units . . . I Know 1 AU is the earth's distance to the Sun. But how do you calculate how far is the Earth is from Neptune or something? Please teach me in Words and Numbers and in Easy steps. If You can please answer this question and teach me in simple steps. The Distance of Saturn from the sun is 9.54 AU and the earth's distance to the sun is 1 AU. - If you put a model earth 1m from the sun, how far would you put Saturn? - If you put a model Earth 50 cm from the sun, How far would you put Saturn? Thanks.
Why do we use AU to measure the distance between a planet and the sun?
For a long time, astronomers didn't know the distance from the Earth to the sun very accurately. But they did know that, for example, Jupiter is 5.204267 times further from the sun than Earth is. So they wrote their reports in units of Earth distance, or AU's. Now we know how long an AU is, but it is still a habit to use AU's. And the numbers come out nice, not too big or too small.
