Hot Super Neptune Burns with Mystery

A hot super Neptune seen by astronomers shouldn’t exist — but there it is, as TESS looks on.

The exoplanet LTT 9779b is far more massive than our own world, and the world is nearly five times larger. Temperatures on its surface put Venus — the hottest planet in our solar system — to shame. This exoplanet, discovered just last year, is so extreme it should not exist — at least not for long.
