The definition of star

I had always been believed that the earth is a star.
So is moon.
But it's NOT.
The Sun is a star because it shines by itself.
But the earth and the moon do not shine by themselves, so you cannot call them "star".

The earth is a planet.
The moon is a satellite.

I just read that a few weeks ago somewhere!

Almost every Japanese people misunderstand that thing I suppose.
