It's been a bit since I uploaded an addon. so here ya go, MY FIRST ADDON FOR 0.990 :) this is the Ran System based on an old Celestia Addon found here: http://www.celestiamotherlode.net/catalog/show_addon_details.php?addon_id=1177  it's not exact and I was too lazy to add every single moon so I only...

JackDole, oh, thanks! I made it in 0980e so I was unaware of the bug in 0980. 

It's been a while since I uploaded something, so here you go. I recently watched "Invasion of Astro-Monster" AKA "Godzilla vs Monster Zero" so I decided to create Planet X which was located behind Jupiter. I placed it at Jupiter's L2 point. add the file to addons>catalogs>planets...

Once upon a time I had an addon that added the hypothetical twin to our sun, nemesis, to the game. I can no longer find it on the addons. am I just missing it?
