‘Super-Earth’ and ‘sub-Neptune’ found orbiting red dwarf

The video discusses exoplanets TOI-1266B and TOI-1266C orbiting a red dwarf star. These planets are close to their star, with short orbital periods. TOI-1266B is a subneptune, while TOI-1266C is a super earth. Both have similar temperatures and compositions, being half rocky and half water. The host star, a red dwarf, allows for potential liquid water on nearby planets. The research was conducted by scientists from the University of Bern and Geneva, using the Saint X observatory.
