Who am I?

I am the closest planet to the sun . I am the smallest planet in our solar system . Who am I ?

I am the fourth planet from the sun . I am called a rocky planet . I am the second smallest planet. Who am I ?

I am the fifth planet from the sun. I have 79 moons. You could fit all the other planets inside Jupiter and still have room.  Who am I ?

I am the second planet from the sun. I am about the same size as Earth. I have no moons. Who am I ?

I have more moons them all the planets, I have more than 20 moons. I am the sixth planet from the sun. Who am I?
