Captain's log - Stardate 2261.401
Every planet and plant satellite in the system near us was rescanned with no further indication of where the missiles originated from. Then Chekov noticed that there was an asteroid in the system that was moving contrary to all laws of physics. Once we focused on it, Spock discovered it was leaving a faint trail behind much the same as the missiles had. An asteroid shaped spaceship?
I've ordered a cautious approach for detailed scanning. If those missiles were from that asteroid, no telling how many more we might have to deal with.
