On an exoplanet called GJ 367 b that's orbiting a star 31 light-years away from our sun, a year only lasts for about eight hours. The discovery could shed light on these mysterious, rapidly orbiting worlds.

Exoplanet GJ 367 b is extremely close to its M dwarf star. These cool red dwarf stars are common in our galaxy and have been known to host multiple planets in a single system, with an average of about two to three planets. Even though they are smaller and cooler than our sun, cool red dwarfs can still heat up planets when they are as close as GJ 367 b is to its star.

Astronomers are eager to learn more about these small planets that quickly spin around their stars in less than 24 hours because they are not sure how they form and end up in such an extreme orbit. This newly discovered planet is close enough to our solar system that researchers were able to gather more data than with other known ultra-short period planets.

"For this class of star, the habitable zone would be somewhere between a two- to three-week orbit," said study coauthor George Ricker, a senior research scientist in Massachusetts Institute of Technology's Kavli Institute for Astrophysics and Space Research, in a statement."Since this star is so close by, and so bright, we have a good chance of seeing other planets in this system.
