What causes planets to revolve around the sun?
The cause of all rotation in the solar system is the rotating gas and dust cloud that the sun and planets coalesced from almost 5 billion years ago. Angular momentum must be conserved and so we continue to rotate today.
Is Gravity on the sun weak?
Gravity on the sun is incredibly strong because of its massive size and density. The sun's gravity is about 28 times stronger than Earth's gravity. This strong gravitational force is what keeps all the planets in orbit around the sun.
Which planets has more of a spherical shape?
There are two planets with an almost perfectly spherical shape. They are Mercury and Venus.
Does Jupiter have the strongest pull of gravity out of all planets?
Jupiter does have the strongest gravitational pull (because of its mass) of all the planets in THIS solar system. However, scientists have now identified over 350 planets orbiting other stars, and among those planets, Jupiter is almost puny. Some of the other exoplanets are more than 10 times Jupiter's mass. But this only makes sense, because an enormous planet would be far easier to detect than an Earth-sized planet from stellar distances.
What is it called when two satellites almost crash into each other?
Gravity
What planets have a surface gravity almost the same as earth?
earth
What is mercurys atmosphere'?
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
Which planet gravitation pull equals that of the earth?
Of the eight planets in orbit about our sun, Venus has gravity almost as strong as ours.
Why is gravity vital?
Gravity is vital because it keeps objects grounded on Earth and helps to maintain the structure of the universe. It plays a crucial role in the formation of stars, planets, and galaxies. Without gravity, life as we know it would not exist.
Why are the planets in the solar system aligned almost completely parallel to each other in their orbits?
They get more or less pulled to where the sun's gravity is the strongest.
What prevent the planets from flying off into space?
The easy answer is gravity. The pull of a star's gravity keeps the planets in orbit in almost equal amounts of centripetal force pulls them away.============================================Another contributor clarified:The answer is 'gravity'. The more massive the body, the more gravity it has."Centripetal force" is any force that pulls awayof the path, such as swinging around a weight attached to a string. The faster you spin it, the heavier it seems to become.

What effect does gravity have on the outer planets?
The effect of gravity does effect the planets. Gravity keeps the planets to the sun. Gravity works between any 2 objects. It's the attraction between planets and sun that keeps planets going around the sun otherwise they would keep going in a straight line.
How large are stars compared with planets?
Almost all stars are significantly larger than almost all planets.
Is Gravity on the sun weak?
Gravity on the sun is incredibly strong because of its massive size and density. The sun's gravity is about 28 times stronger than Earth's gravity. This strong gravitational force is what keeps all the planets in orbit around the sun.
How is gravity used in gymnastics?
Gravity is not "used". In gymnastics, gymnasts almost defy-gravity by flipping in the air but have no control of what gravity does.
What is near weighlessness almost zero gravity?
Near weightlessness, or almost zero gravity, occurs when an object or person is in free fall, such as when skydiving or aboard an airplane in a parabolic flight path. In these conditions, the sensation of weight is greatly reduced due to the lack of support force from a solid surface, allowing for experiences similar to being in space. Astronauts in orbit experience true zero gravity due to the constant free fall around Earth.
