LHS 1815 b (also TOI-704 b) is a thick disk exoplanet, discovered in 2020 by TESS. The planet is located outside the galactic plane.[1]

Characteristics[edit]

LHS 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[edit]

The orbital period is 3.81433 days and the semimajor axis is 0.0404 au.[2][3]

Other designations[edit]

LHS 1815 b is also known as TOI-704 b and TIC 260004324 b.[3]
