It isn't. Gravity can be viewed as emanating from the centre of a body with mass. As the distance increases from the centre then the gravity decreases.
Only indirectly, since the gravity keeps the Sun together, and therefore, hot.
The sun gravity is stronger
Mercury does get affected by the sun's gravity, which keeps it in orbit around the sun. However, the speed at which Mercury orbits the sun, along with its distance from the sun, allows it to maintain a stable orbit rather than being pulled in completely.
The sun itself
The Sun's gravity, at its surface, is about 28 times Earth's surface gravity.
Actually the gravity cannot affect the suns movement. But without gravity, every planet would stop orbiting and sail off out of here in a straight line.
the suns gravity keeps the planets in orbit
Yes, it is.
The sun gravity is stronger
No, Earth's gravity would not affect Pluto. However, the suns gravity does.
Yeah
well pluto is so far away that the sun rays can't reach out that far for it to be warmer and for earth,the earth is much closer and could get most of the suns hot rays
