Scientists have discovered a unique rocky "super-Earth" orbiting one of the oldest stars in the galaxy
RIVERSIDE, CALIFORNIA — Scientists have discovered a unique rocky "super Earth" near one of the oldest stars in the galaxy, according to a statement from the University of California, Riverside.
The planet, known as TOI-561b, is located 280 light-years away in a part of the Milky Way known as the galactic thick disk.
TOI-561b is about 50 percent larger than Earth and roughly three times its mass and roughly the same density. It orbits a star named for NASA's Transiting Exoplanet Survey Satellite — TESS Object of Interest 561, or TOI-561.
Discovery of planet TOI-561b and observations made about its composition have been accepted for publication in the Astronomical Journal.
