Lalande 21185 (also known as Gliese 411) is a red dwarf about 8.30 light-years away in the constellation Ursa Major. Like Barnard's Star, it has been subject to disproven claims of exoplanets in the 20th century, but observations from 2017-2021 have confirmed two worlds orbiting this star, a super-Earth and one of the few known Neptune analogues.
