by Professional astronomers and citizen scientists from the NASA-funded Planet Hunters TESS project have discovered a two-planet system around the bright Sun-like star HD 152843.
HD 152843 is a G-dwarf star located about 352 light-years away in the northern constellation of Hercules.
Otherwise known as TOI-2319 or SAO 84691, the star is about the same mass as the Sun, but almost 1.5 times bigger and slightly brighter.
The inner planet in the HD 152843 system is about 3.4 times bigger than Earth and 11.6 times as massive. Named HD 152843b, it completes an orbit around its star in about 12 days.
The outer planet is about 5.8 times bigger than Earth and 27.5 times more massive, making it a sub-Saturn. Named HD 152843c, it has an orbital period of between 19 and 35 days.
