LHS 1815 b (also known as 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, discovered by TESS in 2020. It is the first known example of a "thick-disk planet" located within the galactic thick disk, a structure 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]
