No. The surface gravity of a planet depends on its size and mass, not its distance from the sun.
True. Gravity on the moon is about one-sixth that of Earth's gravity.
The inner planets are closer to the Sun compared to the outer planets, have solid rocky surfaces, and are smaller in size compared to the outer planets.
No, gravity holds planets in orbit around the sun because the sun's gravity pulls on them. This gravitational force between the sun and planets keeps them in their respective orbits. The force between planets themselves is much smaller and mainly affects their interactions with each other rather than their orbits around the sun.
That's one of Kepler's three laws of planetary motion, which he figured out fromstudying Tycho's lifetime of watching the planets and keeping notes.About 100 years after Kepler, Newton wrote his theory of universal gravitation,and showed that if gravity is true, then the planets mustbehave that way.
Basically it is because the force of gravity is greater nearer the star so it acclerates the star even more. A more mathematical answer: The force of gravity is given by the formula F = GMm / r^2 Where G is a really small number used as a constant of proportionality, M is the mass of the star, m is the mass of the planet and r is the distance between them. The force of gravity is acting as a centripetal force on the planet and we know that for a centripetal force is F = mv^2 / r Where v is the velocity (speed) of the planet. We can combine the two formulas to give v = sqrt(GM / r) So a planet will move faster if the star is more massive or it distance from the star is smaller.
Well sometimes it is and sometimes it isn't. That old saying is not nessary true. Because there are plenty of planets in the universe that are the same size as earth but have less gravity than earth.
No. The reverse is true.
True. Gravity on the moon is about one-sixth that of Earth's gravity.
No, that's not true. All planets, moons, and stars have gravity. Actually all objects have gravity, it's just not very strong for small objects.

YES!
Gravity is stronger on some planets because the planet's core is much more dense. Making it's gravitational pull stronger. Which is making gravity stronger. that is sortof true
Yes it is because because hte closer they are the greater the force.
true
False. The presence of gravity does not directly affect the amount of gas in an atmosphere. Factors such as temperature, pressure, and chemical reactions play a larger role in determining the composition and amount of gas in a given atmosphere.
false, meters are asteroids in the earth atmosphere
