Hitchhiker Star ID help!

Found this little star 2 days ago. Appears to come out at night only and is small like size if pencil eraser head. Thanks for all your help in advance. Really want to know if it's good or bad.

Looks like asterina star. Totally harmless. Check the hitch hiker link in my signature, that will help.
