Astronomers spot 2 intriguing alien worlds around an ultracool star

A global workforce of astronomers has found two new super-Earths orbiting a distant ultracool dwarf star 100 light-years from Earth.

The newly noticed exoplanets orbits the second coolest star ever discovered with planets round it. The system’s interior planet, designated LP 890-9b, is about 30% bigger than Earth and quickly orbits the dwarf star in simply 2.7 Earth days. The second planet, referred to as LP 890-9c, is barely bigger, about 40% the scale of Earth, and completes its orbit in about 8.5 Earth days. Astronomers imagine that this second planet is within the liveable zone of its star, the place it’s neither too sizzling nor too chilly to assist the existence of liquid water on its floor.
