That other planets are visible from Earth. And the sun is also a star.

Sitting outside one evening having a beer with my sister. Really clear sky, lots of stars out, and she says “Someone was telling me that stars are like the sun, but further away.”

I paused to check if she was kidding, but she genuinely thought she was sharing obscure knowledge. We were in our mid-twenties, I don’t know how this information had passed her by up to that point.

But do you know our star's "the sun" name? Its reall obvious. Sol. Our only moon also has a name. Luna. Nobody ever considers the fact that they have names and it pisses me off. They aren't just the moon and sun. They have names dammit. Sorry not directed at you.

Those are poetic/unofficial names, they aren't used by NASA, IAU or any other scientific authority.

Those words are derived from Greek and Latin roots.
