The acceleration of gravity on the surface of any astronomical body depends on
its mass and the distance of its surface from its center ... the 'radius'. Whatever
the nature of gravity on its surface is, that's the reason.
I was about to say "It doesn't.", but I don't know whether you consider Pluto to be
a planet any more. Mercury's gravity is more than 6 times as strong as Pluto's is.
And it's also more than double the strength of gravity on the surface of our Moon.

This iron rich molten core allows it to have a strong magnetic field. The only other rocky planet with a molten core is earth.

Which object in our solour system has the biggest gravitational pull and why?
In our solar system it would be the sun. But there are much more massive objects beyond our solar sytem that would have a higher pull - the more massive an object is the higher its gravitational pull. a black hole has a huge gravitational pull, so strong that light cannot escape.
Why do all the planets revolve around the sun?
All planets revolve around the sun because it has a strong gravitational pull.
If the average distance between Earth and the Sun were doubled what changes could occur in the Suns gravitational pull?
Its pull on the earth would be 25% as strong.
What does the Moon's gravitational pull causes?
sun and the moon
What caused the Moon's gravitational pull?
sun and the moon
Does the sun have a strong gravitational pull?
Yes it does.
Does the sun have gravitional pull?
Yes, It has a strong gravitational pull. Without the gravitational pull, none of the planets would orbit it.
What is the relationship of the Sun to the planets?
The sun's so large that its gravitational pull is very strong, but just strong enough to hold the planets in place. So the relationship is its gravitational pull.
Which object in our solour system has the biggest gravitational pull and why?
In our solar system it would be the sun. But there are much more massive objects beyond our solar sytem that would have a higher pull - the more massive an object is the higher its gravitational pull. a black hole has a huge gravitational pull, so strong that light cannot escape.
Why do all the planets revolve around the sun?
All planets revolve around the sun because it has a strong gravitational pull.
Why do the planets circle the sun?
gravitational force
Why dont the sun suck us up?
The sun will not suck us in because its we are to far away and its gravitational pull is not strong enough.
What keeps earth in its orbit?
The sun's gravitational pull keeps the earth in orbit around it.
Does our Sun have a gravitational pull?
Yes, everything in the cosmos has a gravitational pull on everything else.
If the average distance between Earth and the Sun were doubled what changes could occur in the Suns gravitational pull?
Its pull on the earth would be 25% as strong.
What is the gravitational pull of the sun and the moon?
The regular rising and falling of ocean water due to the gravitational pull of the Sun and Moon is called
Why the planets keeps on their orbits?
The Sun has a massive gravitational pull, it is strong enough to hold the planets in their place while they orbit it.
