Does it make sense to have a world with a very quickly orbiting moon?

I am writing a story in which a planet has a moon that orbits it about once a minute. In the story, the moon is pretty bright too, so the night sky has a little bit of a slow strobe light effect: 30 seconds really bright, 30 seconds dark, etc. The planet itself rotates pretty slowly, so the nighttime is about 48 hours long. The point is that the long nighttime is pretty annoying.

My questions:

• Is there any reason why this wouldn't be possible?
• What would the effects of such a quickly orbiting moon be on this planet? (Another potentially relevant fact: the planet is about half the size of earth, with about half the gravity. It does have water, not clear yet exactly how much).
• What would make the moon extra bright? An extra bright sun? Or could it be something else?
