LTT 1445 A B is about 22 light-years away from Earth. Because its orbit is too close to its parent star, scientists believe that its surface temperature is very high, about 320 degrees Fahrenheit, likeOvenIt's just as hot.

The planet is on a stable orbit around its star, but a pair of brotherly stars orbit each other at a far distance, and the planet stars run around these stars. This makes the LTT 1445A a part of the three-sun system. NASA points out that all three stars in the LTT 1445 system are red dwarfs. The red dwarf is smaller, and the temperature is lower, but the time of the combustion is longer.

The nearest transitional planetary system discovered so far is HD 219134 bc, about 21 light-years away.
