About 1,400 light-years, toward Auriga

WASP-12b is about 1,400 light-years away, toward the constellation Auriga. It is the farthest planet on this map. It skims so close to its star that it goes around once every 26 hours or so.

A planet being eaten by its star

This planet is so close to its star that the star’s pull is thought to stretch it into a long shape pointing at the star. From the stretched tip, the planet’s air is pulled off toward the star. The planet’s orbit is also slowly shrinking toward the star.

Why?Since it was found in 2008, the time between its passes in front of the star has been getting about 0.03 seconds shorter every year. That means its path is shrinking.
