They are spherical by their own gravity.


The Sun is made up of gases, most of them (inside) in plasma state, fueling a gigantic nuclear reaction.

The Earth is made up mostly of rock, with an inner core of iron and nickel. The inner part is in a liquid state (=hot).

The Moon is made up of rock only. All of it is in solid state.

And of course the sizes are quite different...
