LP 890-9, also known as SPECULOOS-2 or TOI-4306, is a high proper motion red dwarf star located 105 light-years (32 pc) away from the Solar System in the constellation of Eridanus.
The outer planet LP 890-9 c orbits within the habitable zone, and is a favorable target for atmospheric characterization using JWST.
[3][7] LP 890-9 c orbits near the inner edge of the conservative habitable zone, and models differ as to whether the planet is more likely to resemble Earth or Venus.
[4] The planet is tidally locked to its host, meaning it has no day-night cycle like Earth.
In addition, the planet is close enough to its star that powerful radiation may reduce its habitability.
