Water-World Super-Earth

 From SciNews:

The TOI-1452 binary system resides about 100 light-years away in the constellation of Draco. Also known as TIC 420112589 or 2MASS J19204172+7311434, it consists of two M-dwarf (red dwarf) stars. The two stars orbit each other once every 1,400 years and are separated by a small distance — 97 AU (astronomical units), or about 2.5 times the distance between the Sun and Pluto. The newfound planet circles the primary member of the TOI-1452 system in a temperate orbit that takes 11.1 days. Named TOI-1452b, the alien world is about 1.7 times larger and 4.8 times more massive than Earth.

“The planet is located at a distance from its star where its temperature would be neither too hot nor too cold for liquid water to exist on its surface,” said Université de Montréal Ph.D. student Charles Cadieux and colleagues. (Read more.)
