A torrid extraterrestrial world was found in orbit around three stars – BGR

NASA's TESS Exoplanet Research satellite has already made incredible discoveries in its first two years of use, but its latest find will certainly look familiar to science fiction fans. The planet LTT 1445 A b is a rocky world about 1.4 times larger than the Earth. It's a likely rock bar with incredibly high surface temperatures, but what makes the planet particularly interesting is that its sky is dotted not with one, nor two, but with three suns.

The planet gravitates around a star at an incredibly close distance, achieving a complete orbit in just five Earth days, and this star revolving around a pair of stars locked in an intimate dance. The three stars are all red dwarfs, which are a little cooler than our own Sun, but that does not mean that 1445 LTT would be a comfortable place to visit.

As NASA explains in a new post, the surface of the planet is probably about 320 degrees Fahrenheit, which would make it much too hot for liquid water to exist on its surface. Liquid water is thought to be a prerequisite for life. It is unlikely that we will find a race of star-worshipers, but the planet is still interesting for researchers.

If you stood on the surface, you could see the nearest star dominating the sky, with the more distant pair of stars shining in the background:

The planet is only 22 light-years away from the planet, which is quite realistic. His discovery was made possible by the angle of its orbit around its host star. When the planet passes the star, from our point of view, the TESS satellite detects a dip in the brightness of the star, suggesting the presence of the planet while revealing the time required for the planet to complete its orbit.
