Asteroid exterior and typos and descriptions for assets beginning with B

Would love to have this new exterior shot in while I'm doing these fixes for assets as there are a lot of D class planets using random shots and station shots depending on whether they are inhabited or not. I am also using it in my new work for inhabited D class planetoids.

Hmmm... what is the best command to use to make my master keep track of the bobbens/naev repo?
I have tried using "git pull upstream master" but I'm not sure that works so well... then afterwards I try and rebase my current branches with my own master with "git checkout ; git rebase --onto master", is that the cleanest way?
Apologies for the constant questions...
