TOI-1798 Planetary System

Caption

Artist’s rendition of TOI-1798, a planetary system that is home to two planets. The new TESS-Keck Survey Mass Catalog shows the outer planet is a sub-Neptune with an orbital period of eight days; the inner planet is a strange Super-Earth that orbits so close to its star, one year on this alien world lasts only half an Earth day.
