EVSN - Lightweight Mars-sized Planet Found in TESS Data

From December 3, 2021.

A Mars-sized planet was found just 31 light-years away, orbiting its star every eight hours and having 55 percent the mass of the Earth, leading scientists to conclude it's mostly made of an iron-nickel core. Plus, water on Earth, a huge comet, and a review of a Canon lens.
