How can the Sun have such a strong gravitational field if it's made of gasses?
How can the sun have a strong gravitational pull if it's made up of gases and not a solid mass like the earth?
The gravitational field of an object is determined solely by:
1) how massive it is, and 2) how far away from it you are
Whether it's a gas or a liquid or a solid doesn't make any difference. The Sun is a lot more massive than the Earth, and so it has a stronger gravitational field. From our everyday experience, it might not be so obvious that a gas has mass, but it's true. The Sun exerts the same gravitational force on the planets as it would if it had the same mass but was made of rock.
