Characteristics
editLHS 1815 b is a terrestrial planet (super-Earth) with a mass of 0.0132 MJ and a radius of 0.09707 RJ and was discovered by TESS in 2020. The planet is the first discovered example of a "thick-disk planet" located within a thick disk, one of the galactic structures much higher, than the positions of other planetary systems discovered by TESS.
Orbit
editThe orbital period is 3.81433 days and the semimajor axis is 0.0404 au.[2][3]
Other designations
editLHS 1815 b is also known as TOI-704 b and TIC 260004324 b.[3]
