Conservation of Momentum Question?
During July 1994 the comet Shoemaker-Levy 9 smashed into Jupiter in a spectacular fashion. The comet actually consisted of 21 distinct pieces, the largest of which had a mass of approximately 4.0 x 1012 kg and a speed of 6.0 x 104 m/s. Jupiter, the largest planet in the solar system, has a mass of 1.9 x 1027 kg and an orbital speed of 1.3 x 104 m/s. If this piece of the comet had hit Jupiter head-on, what would have been the change (magnitude only) in Jupiter's orbital speed (not its final speed)?
If Jupiter is made up of entirely gas, why do comets slam into them and explode like it hit a solid ground (e.g. Shoemaker-levy 9 comet in 1994)?
You know what else is made of nothing but gas? The Earth’s atmosphere.Do you know what happens when something moving 17,000 mph, like The Space Shuttle, hits it? The extreme compression of the air molecules heat the surface quite a bit. Without proper shielding, the Spacecraft would explode. Tragically, this has happened.Many other things that have no heat shield hit Earth’s atmosphere, and are incinerated before they hit the ground. We call them shooting stars.The point is, just because something is a gas, and seems to be rather light and immaterial, and the molecules are comparatively far apart, does not mean they don’t exist. Gas molecules are there. And when something the size of a comet crashes into them at many times the speed of the fastest bullet, it’s going to great a LOT of friction… And a gigantic explosion.In the case of Comet Shoemaker-Levy, that thing created wounds in the atmosphere that were larger than the Earth.
What comet collided with Jupiter in 1994?
Perhaps you are confusing Quora with Google. This sort of shallow factual information can be easily and more quickly found on Google. A more appropriate Quora question asks deeper question like “How did they identify that a comet would impact Jupiter in 1994?” or “What did we learn from the comet impact of Jupiter in 1994?”To answer your question, it was Shoemaker-Levy 9. Entering your question word for word provided instantaneous results. Please consider using Google for simple factual questions, and Quora for deeper questions.
Question on comet twice the size of jupiter?
I just watched this presentation (on the internet) that was given by Nassim Haramein. He said that in 2003, a comet twice the size of jupiter passed by earth and almost hit the sun. He even showed nasa satellite footage of it going by. Its tail was almost the size of an astronomical unit. He said that some people got pictures of it from earth with their cameras. Does anyone have these?
How can the composition of water found on the comet 67P examined by the Rosetta orbiter be different from Earth's water composition?
D/H ratio. Deuterium (D) is a Hydrogen isotope with an extra neutron in its nucleus. Therefore it's also called Heavy Hydrogen and combines with Oxygen to form Heavy Water. The water on Earth has a D/H ratio of about 1/6000. The water on 67P has thrice that D/H ratio. Therefore, their compositions are different. The main implication of these findings is the reinforcement of the theory that water did not come to Earth from Jupiter family comets, as the D/H ratio is quite stable for waters on different celestial bodies. We should be looking to asteroids for answers.
Is it true that in February of 2003, a comet, twice the size of Jupiter passes through the solar system?
What a load of crap.... also this video has stolen the title, since there is already a "unified field theory" in physics, which is completely different to what is burped there. The guy is just producing hot air. Especially since the first prediction of a periodic comet is just 400 years old. Just picking one comet in 2003 (we have comets every year) and claim somebody predicted exactly this comet AFTERWARDS is only impressive for complete idiots. Choose your comet that passed through the inner solar system in 2003: http://www.theastronomer.org/2003comets.html The biggest known comet (without dust and gas tail) in history was Hale-Bopp, with about 40 km diameter.
How can 288P be both an asteroid and a comet?
I quote myself from the press release I wrote here: Hubble discovers a unique type of object in the Solar SystemUnderstanding the origin and evolution of main-belt comets — asteroids orbiting between Mars and Jupiter that show comet-like activity — is a crucial element in our understanding of the formation and evolution of the whole Solar System. Among the questions main-belt comets can help to answer is how water came to Earth [2]. Since only a few objects of this type are known, 288P presents itself as an extremely important system for future studies.
How could comet shoemaker crash into jupiter if jupiter has no surface?
Jupiter may be described as a gas giant, but it doesn't mean it's the same consistency as a light fog outside your window. The gas becomes dense not very far "down", and the density increases rapidly. The Galileo probe that dropped into Jupiter's atmosphere was crushed having penetrated a tiny percentage of the way in. The meteors you can see most nights in your own sky are usually grain-of-sand size, up to pebble-sized, and they cause a small light show on Earth even though they burn up in the thin outer atmosphere. The comet fragments that hit Jupiter were miles in diameter and travelling at many miles per second relative to Jupiter. At that speed, colliding with anything will cause an explosion. The fragments would have vaporised very rapidly.
Will comets and asteroids that collide with Jupiter give it a solid core and enough mass to influence other planets' orbits?
As Rob Weir says, negligible mass. The total mass of the asteroid belt is only about 4% of the mass of the Earth's Moon. (See the Wiki, Asteroid belt.) The total mass comets might be twice the mass of Earth, assuming the Oort cloud is as big as we think it is. (The mass of the Oort cloud.) But it is unlikely many of these could ever be absorbed by Jupiter. And the core of Jupiter may be solid already, no one is entirely sure.
Could an asteroid become a comet, or a comet become an asteroid?
Could an asteroid become a comet, or a comet become an asteroid?There are two major differences between an asteroid and a comet:the orbit of a comet is extremely long cutting across the plants orbits, and tend not to be in the same plane as the planet orbits. One orbit can take thousands of years… Or like Halley’s comet which takes “only” 74–79 years. Asteroids are in the planetary plane, Most are between Mars and Jupiter, with a few that cross some of the inner planets orbit.the amount of ice. The nearby asteroids that do cross the inner planets orbits have lost their ice long ago.#2 is the weaker of the two, as the Perseid metor showers are the remains of an old comet that has lost its water and broken up.It is POSSIBLE for a comet to impact some asteroid with the remains of the comet to stay roughly in the area of the asteroid belt… but not likely.
