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.
Mercury is very dense. It has a lot of matter in a small space. It is thought to be the core of a much larger planet. The planet has a high iron content and a partially molten core. This iron rich molten core allows it to have a strong magnetic field. The only other rocky planet with a molten core is earth.
because it is very small and can carry itself easily.
Because Mercury has no moons, therefor no gravitational pull.
because it has no atmosphere
its density
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.
All planets revolve around the sun because it has a strong gravitational pull.
Its pull on the earth would be 25% as strong.

Yes it does.
Yes, It has a strong gravitational pull. Without the gravitational pull, none of the planets would orbit it.
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.
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.

gravitational force
The sun will not suck us in because its we are to far away and its gravitational pull is not strong enough.
The sun's gravitational pull keeps the earth in orbit around it.
Yes, everything in the cosmos has a gravitational pull on everything else.
Its pull on the earth would be 25% as strong.
The regular rising and falling of ocean water due to the gravitational pull of the Sun and Moon is called
Gravitational pull is so the planets keep orbiting around the sun because of its gravitational pull
