L 168-9 is a star with 0.62 times the mass of the Sun, and 0.6 times its radius. It is located 82.03 light years away from the solar system.
L 168-9 is known to have 1 exoplanets in orbit around it.
L 168-9 b was discovered by the Transiting Exoplanet Survey Satellite (TESS) observatory, in 2020-04, using the transit method. Its semi-major axis is 0.02 astronomical units, as compared to Earth's which is 1 astronomical unit. The mass of L 168-9 b is 4.601 times the mass of Earth. The radius of L 168-9 b is 1.390 that of Earth. At 4.601 Earth masses, L 168-9 b is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes. No Super Earths are known to exist in our solar system, but if it exists, the so-called Planet Nine could very well be a super Earth, as it is hypothesized to have a mass between five and ten Earth masses.
