LHS 1815 b (also known as TOI-704 b) is athick disk exoplanet discovered in 2020 byTESS . Theplanet is located outside thegalactic plane .[ 1]
LHS 1815 b is a terrestrial planet (super-Earth) with a mass of 0.0132MJ and a radius of 0.09707RJ , discovered byTESS 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."
The orbital period is 3.81433 days and the semimajor axis is 0.0404 au.[ 2] [ 3]
LHS 1815 b is also known as TOI-704 b and TIC 260004324 b.[ 3]
