My Submission is my favorite system I found during Distant Worlds.

This system is cool for 3 and a half reasons.
First it is a System Nebula system meaning that there is a cool cloud of gas around the system giving all the backgrounds while inside the system this cool glow that unfortunatly I don't have any screenshots of anymore
Second. There is a Neutron Star at the center of this system
Third. There is also an Earthlike out at the 3rd star shown in my imgur gallery above
1/2. There's a landable Ringed planet. I haven't been there but it seems it could be a good location for a landable waypoint.
