With Tianwen-2, China Enters the Asteroid Race

I missed some interesting news a couple months ago, and I'm guessing you did, too. The launch of China's Tianwen-2 on May 28 took place without much fanfare. Just one space probe among many.

The Slow Dances of Asteroid Moons

An astronomy pop quiz for you: How large does a planet have to be before it can have a natural satellite of its own? It's a trick question, you see. There's no lower limit.
