Why are some names on the galaxy map screen in a diffrent colour?

the ones in green are (n) status planets, less than 1/5 of your points, the orangish red ones are (s), more than 5x your points, the bold red are your planets, the white means they are between 5x and 1/5 your score, so like if you had 1000 points all white would show players that have between 5000 and 200 pts.

NOTE that if you have a moon, your planets will show white when you have the moon toggled as your current location, but bold red when you have a planet toggled.
