That’s Phobos, the bigger moon. I wonder how Deimos would look in transit.

We had a discussion a few years ago here about the escape velocity for Deimos. We calculated that you couldn’t jump off the moon, you couldn’t throw a football to Mars, but you could hit a golf ball that would go into space, IIRC.
