- NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered a planet named HD21749b orbiting around the star HD 21749.
- The planet lies about 53 light years from earth in the faint constellation reticulum.
- HD 21749b completes one orbit of its host star, which is nearly as bright as our sun, every 36 earth days.
- It is a “sub Neptune”, around three times bigger than earth and 23 times more massive then earth, which means it’s likely gaseous rather than rocky.
