Astronomers have discovered a 170 million-year-old giant exoplanet named “GJ 523b” (informally called “mega-Earth”).
The planet, having a mass 23 times that of Earth, is over 2.5 times larger in size.
It was initially detected by the NASA Transiting Exoplanet Survey Satellite (TESS).
It is to be noted that its existence was confirmed by Max Krof from the Wisconsin Center for Origins Research (WiCOR).
