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.
True
No, the more mass of an object the more gravity it exerts.
true
in most cases, a star is bigger than a planet. yet, both stars and planets have different sizes, such as a white dwarf star is smaller than Jupiter.
gravity
For the most part, yes. But the actual determining factor for how much gravity a planet has is based on its mass, and since size and mass are often related it is somewhat accurate to say that the bigger the planet is, the more gravity it will have.
that is not true
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
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.
True
No. The surface gravity of a planet depends on its size and mass, not its distance from the sun.
Yes because if a Star has a planet the gravity of the planet will rock it back and forth
No, the more mass of an object the more gravity it exerts.
true
Sort of a Meteor is a part of an Asteroid, but it starts to burn up in entering the earths atmosphere
No.
Not a chance
