An international research team including astronomers at the University of Birmingham, has just announced the discovery of two “super-Earth” planets orbiting LP 890-9, a small, cool star located about 100 light-years from Earth.
The star, also called TOI-4306 or SPECULOOS-2, is the second-coolest star found to host planets, after the famous TRAPPIST-1. This rare discovery is the subject of a forthcoming publication in the journal Astronomy & Astrophysics.
The system’s inner planet, called LP 890-9b, is about 30% larger than Earth and completes an orbit around the star in just 2.7 days.
