LHS 2335 Gliese 3634

Wiki

Gliese 3634 (Often shortened to GJ 3634) is a red dwarf star in the Hydra constellation. One planet has been discovered in its orbit, Gliese 3634 b. GJ 3634 is under half the mass and size of the Sun, and is estimated to be at least a billion years younger, and lies near to Earth, with a distance of 19.8 parsecs (64.6 light years). It was targeted by astronomers during an over six-year survey of red dwarfs. The astronomers had recently changed their strategy to search for planets with extremely short orbits so they could narrow down candidates that transited, or crossed in front of, their host stars as seen from the Earth. The Super-Earth GJ 3634 b was the first planet discovered using this new strategy. The planet was confirmed using Doppler spectroscopy, or the observation and extrapolation of data from a recorded Doppler effect in the star's light, but later observations found no transiting pattern. The planet was published by its discoverers on February 8, 2011.
