Astronomers Discover Three Super-Earths Orbiting Nearby Star

Astronomers have discovered a planetary system orbiting a star only 54 light-years away with the Automated Planet Finder (APF) at Lick Observatory and ground-based telescopes in Hawaii and Arizona. The team discovered the planets by detecting a wobble of the star HD 7924 as a result of the gravitational pull of the planets orbiting around it. All three planets orbit the star at a distance closer than Mercury orbits the Sun, completing their orbits in just 5, 15, and 24 days.
