Starship Asterisk*

What's the spiky red object north of NGC 3808B? I'd say a nearby star, except that it doesn't look round and seems to be leaving a faint trail in the 2 o'clock direction!

They have enough angular separation that it does matter, as you have observed. I was able to quite easily recreate a similar set of illuminations using Universe Sandbox. I made the background gray so that the whole spheres of both bodies are visible. Edit: To add further to this observation I would...

I'll admit I'm not good with 3-dimensional relationships, but I assume that the Sun is essentially equidistant from Earth and Moon. So, they should be equally illuminated. Why does the Moon appear "fuller" than Earth?
