A strange exoplanet sitting 53 light years from Earth has been discovered by astronomers using the TESS spacecraft. This world is three times larger than the Earth, but 23 times as dense. This suggests it is likely surrounded by a thick atmosphere, denser than that seen on Uranus or Neptune. The planet, HD 2172b, speeds around its parent star once every 36 days. This is the third confirmed planet found by TESS, although astronomers are looking through data showing more than 280 other potential worlds.Read More Weird Exoplanet Discovered by TESS Spacecraft – Strange World, Indeed!
