    Ross 128b – A Nearby Earth-Sized World

    Ross 128 is what astronomers call a red dwarf star, and around it, the High Accuracy Radial Velocity Planet Searcher (HARPS) instrument at the European Southern Observatory, discovered an Earth-sized planet, just 11 light-years away. HARPS make its predictions and discoveries by measuring the wobbles that happen in stars when its planets influence their position in the sky, pulling on them. Red dwarf stars are commonly known for their violent eruptions of radiation, strong enough to sterilize their own planetary system. But looking at the data from the European Southern Observatory, so far Ross 128 seems to be quiet than most red dwarfs. Closer to us is Proxima Centauri b,…
