Here's a video of an asteroid - (36) Atalante moving through the northern sky during a four hour period. It's about 1.3 astronomical units from us, so it appears as just a moving bright dot. In this time lapse video the asteroid travels over 300,000 km through space #astrophotography

A blinking star, HT Cassiopeiae - a star in the constellation Cassiopeiae that dims every 1.77 hour.
