Jupiter moving closer to the sun?

Question

I recently saw a documentary of how scientist have found stars having a planet as big as jupiter orbiting at an amazingly high speed....could jupiter get closer to the sun and if so would earth be destroyed?

well it would be an amazing thing to see i guess...But when mars and its moon collide willit have any effect on earth

Answer 1

No. The reason is a bit complex for someone not already familiar with the conservation of rotational inertia. But the short answer is that Jupiter is probably moving very, very slowly away from the Sun. Our moon is moving very, very slowly away from the Earth. Each body that has satellites has what is called a "Roche limit". Jupiter and Earth would be outside of the Sun's Roche limit so they will move slowly farther away. Our moon is outside Earth's Roche limit and will move slowly farther away. Mars is pretty cool. Mars has 2 very small moons. One, Diemos, is farther away from Mars and outside its Roche limit. It will also continue to move farther away ever so slowly. But the other moon, Phobos, is a bit closer and inside of Mars' Roche limit. It will ever so slowly move closer to Mars until it spirals down and eventually collides. COOL, huh?

Answer 2

Right now I have been unable to find any evidence of Jupiter moving any closer (Radius of Orbit decreasing) to the Sun.
I also saw those reports of distant Stars having planets and
was not surprised. In the Milky Way alone there are estimates of 100 billion stars. It is not foolish to presume that each of those stars has from 0 to 10 planets orbiting it. The problem is that these planets are not burning (shining brightly) and therefore not normally visable to us, from far away, in the same way that the stars themselves are. The brightness of the distant stars tends to blind us and prevent our recognition of their nearby planets. You might grasp this idea if you looked into the bright headlights of an automobile some evening. When you do that, everything else around the auto headlights is blacked out.

Answer 3

The earth goes through warm and cold periods, this has been proven. There is no global warming or earth getting closer to the sun. In a few million years well be in an iceage again and a few million after that, warm period. Where comming down from our last ice age right now in fact. Its also been proven that space and the universe is expanding at a constant rate, the sun moon and anything else in the universe is getting farther away, not closer.

Answer 4

The planets are "placed' according to their density.
The inner planets have metallic cores. Neptune is likely to be fresher water, Uranus is likely to be saltier water, while Saturn is gases...therefore Jupiter is just sand and will not be moving closer to the sun ever since the the sun is traveling very fast and the planets lag behind it some..

Answer 5

no because the suns gravity is keeping us all were we are but if jupiter is moving towanrds the sun it means its broken free of the gravitational pull with it being such a big planet but as it gets closer the gravitational pull gets much stronger so stopping jupiter from moving closer and it would slowly be put back into place were it came from

i am the best scientist around so i asure you my advide is the best

Answer 6

no

there is more chance of Jupiter turning into a star then it changing orbit and colliding with the earth

Answer 7

Jupiter is not moving closer and is too heavy to suddenly change its orbit.
If Jupiter collided with the earth we would all be killed!

Answer 8

are you gonna play pool with the planets??
Apparently the orbits of all the planets display 'chaotic' behaviour. Nonetheless, Le Verrier(18Cent), I believe, using Newtons laws and elementary perturbation theory, was able to prove that the Solar System is inherently stable. (No I cannot be arsed looking up his proof!)

Answer 9

No the SUN will eventually expand & destroy the Earth.

Answer 10

i like jupiter.
he is one of the best on never mind the buzzcocks.
bit fat though.
