Episode Details

Astronomers have discovered thousands of exoplanets, and still need to confirm thousands more. And over the coming decades, we’ll probably learn of millions of planets, orbiting stars we’ve never heard of.

That’s why it’s reassuring to know astronomers are learning a tremendous amount about the closest star system to our own, Proxima Centauri. In fact, we now know of two planets orbiting the red dwarf star, one of which is in the habitable zone.
