Transiting Exoplanet Survey Satellite (TESS), NASA's latest planet-hunting probe, has discovered a new world outside our solar system, orbiting a dwarf star 53 light years away. This is the third new planet confirmed by TESS since its launch in April 2018. The planet has been named as HD 21749b. The planets orbits a bright, nearby dwarf star about 53 light years away, in the constellation Reticulum, and appears to have the longest orbital period of the three planets so far identified by TESS.
