What else can I help you with?
What holds all moons to every planet in their orbits?
Gravity. As the planet rotates it's mass holds it's moons within it's orbit. The larger the planet the stronger is its gravitational pull.
Do all of the moons not have gravity?
Everything has gravity, the bigger it is the more it has. Moons DO have gravity, but it might be less than Earth's.
Is there grivity on Jupiter?
There is gravity. There is gravity on all planets, moons, and stars.
Is there gravity in space and why?
Yes. Gravity is a force of attraction that exists between all objects with mass. It increases with the mass of the object in question and decreases with distance from it. Planets, stars, moons, and galaxies all exert a gravitational pull.
What force keeps the moons of Jupiter in orbit around the planet?
The moons stay in orbit around Jupiter by the force of gravity.
What is gravityy?
Gravity is a force pulling together all matter (which is anything you can physically touch). The more matter, the more gravity, so things that have a lot of matter such as planets and moons and stars pull more strongly.
Do only planets exert gravity?
No. Anything with mass exerts a gravitational pull. The strength of that pull is directly proportional to an object's mass and most objects do not have enough mass of their gravity to be noticeable. It starts to become noticeable with objects on the level of large asteroids and comets and small moons. Stars, which are far more massive than planets, have far stronger gravity. Black holes have the strongest gravity in the universe.
What objects have gravity?
All objects with mass have gravity, but larger objects typically have a stronger gravitational pull. This includes planets, stars, moons, and even smaller objects like people or cars. The strength of gravity depends on the mass of the object and the distance from it.
Why does Jupiter have more moons while Venus and Mercury have no moons at all?
Jupiter is very close to the asteroid belt - pretty much an area where a bunch of loose space debris could be caught up in Jupiter's gravity at any second. Also Jupiter is significantly bigger than Venus, actually over 100x bigger. Since Jupiter's gravity is much larger than Venus's gravity, it can pull in more moons to orbit around it.
Why neptune gravity pull people in?
Gravity is an attractive force that occurs between all objects with mass. The gravity of any planet will pull objects in.
Is gravity the same on all planets and moons in the solar system?
No. Gravity from any object varies depending on its size and mass.
Why are mars moons round?
Phobos and Deimos (Mar's moons) are not perfectly spherical. They are actually just captured asteroids. However, most moons and plants are round due to the following: Their is no gravity in space. So when the universe was formed, there were all these particles just floating around. All matter in space has their own gravitational field (a very small gravitational pull). When all that space dust was flying around, some of the particles got close enough to one another to stick (do to their individual gravitational pull). As more and more particles started sticking together, the gravitational pull gets stronger. As these masses were "growing" they "grew" evenly in all directions forming spherical entities.
