If the sun has gravity and pulls on the Earth, why doesn't the Earth get pulled into the sun?

• Because the Earth had enough mass to keep itself in orbit around the sun.

• Because the Sun's gravity is not very strong.

• It does pull the Earth towards the sun, but very slowly so we don't notice.

• The sun has to pull on 7 other planets and can't pull them all in.
