M_Sipher is correct, that was never in vanilla. It may have been part of a mod, however. Slightly off-topic, I kinda miss the planets having 100 levels. Would love to see a mod bring that back.
They were indeed. Code: "orbitRegions" : [ [ [3, 3], "Hot" ], [ [4, 9], "Mild" ], [ [10, 12], "Cold" ] ]
I came up with another idea, how about a new asteroid belt type called Starship Graveyard. In this new biome we would have old junked satellites (Junk Tech Blocks), spaceships (Techs and Scrap you might be able to use to upgrade your ship, yourself, and your stuff) , and random metal rich asteroids (Rare Ores) mixed in.
Plus raider scavengers and hitch hiking fauna from other worlds. Literally, any creature could spawn in this habitat.
In addition it would be the perfect place to have a build your own Outpost themed base thing going on.
I did a little searching around on the forums and found this mod that i think you will be interested in. ( http://community.playstarbound.com/resources/classic-grey-alien-race.389/ )
The new star types and stuff already seem to exist in a couple of mods after doing some searching through the forums. I started using these three mods in conjunction to acquire the results this thread was looking for.
