Using NASA’s Transiting Exoplanet Survey Satellite (TESS) and the HARPS fiber-fed Echelle spectrograph mounted at the 3.6-m telescope of ESO’s La Silla observatory, astronomers have discovered and confirmed two massive transiting planets around the G-type dwarf star TOI-763.

“Only 70 such planets are reported orbiting G-stars in the NASA archive as of June 2020.”

TOI-763 is a relatively bright G-type star located 311 light-years away in the constellation of Centaurus.

Also known as TIC 178819686, CD-39 7945 and 2MASS J1575245-3945275, the star is around 10% smaller than the Sun.

Young star system K2-33 hosts a planet that orbits 10 times closer to it than Mercury does to the Sun. The planet, named K2-33b, is slightly larger than Neptune and is only 5-10 million years old. It's the "youngest fully formed exoplanet ever detected," according to NASA's Jet Propulsion Laboratory
