It is located about 8.3 light-years away in the constellation Ursa Major. It is suspected to have at least one, but perhaps as many as three, Jupiter-class planets. 44 Closest Stars and How They Compare to our Sun. - Added GJ 458 and updated GJ 251 and Lalande 21185 (S. Stock, et al.). Lalande 21185 este o pitică roșie din secvența principală, care se deplasează relativ repede urmând o direcție perpendiculară față de planul galactic, la o viteză de 47 km/s. It is the fourth closest star system to the Sun at 8.3 ly. The star is less enriched in elements heavier than hydrogen ("metals") compared to our Sun, with around 63 percent of Sol's abundance of iron (Cayrel de Strobel et al, 1991, page 292). The age of modern man. It is difficult to pin down the age any more precisely since stars of this type evolve so slowly over lifetimes that are on the order of hundreds of billions of years.

Humans have been fascinated by the stars in the night sky since the dawn of time. "This cool and dim, main sequence red dwarf (M2.1 Vne) has about 46 percent of Sol's mass (RECONS estimate), 46 percent of its diameter (Johnson and Wright, 1983, page 671), but less than 6/1,000th of its brightness. (Solstation). Subatlantic Age (2.5-0.0 TYA) - Subboreal Age (5.0-2.5 TYA) - Atlantic Age (7.5-5 TYA) - Boreal Age (9-7.5 TYA) - Preboreal Age (10.3-9 TYA) - First stage of the Holocene. and numerous stellar companions to TESS candidate systems (Mugrauer & Michel). In contrast to many other red dwarfs, Lalande 21185 is, according to the latest findings, probably not a flare star (eruptively variable star with aperiodic temporary releases of large amounts of energy), but a relatively quiet representative of its spectral type. Lalande 21185 A red dwarf with perhaps two planets, both gaseous giants, which are far away from the star. (PROSE: Return of the Living Dad) The fourth planet orbiting the star was home to the Caxtarids. The low level of activity, its orbit through the galaxy and other properties suggest that Lalande 21185 is older than the Sun with an age somewhere in the 5 to 10 billion year range. Despite being one of the brightest stars, it is too dim to see without a telescope. Lalande 21185 is a red dwarf star in the constellation of Ursa Major.Although relatively close by, it is only magnitude 7 in visible light and thus is too dim to see with the unaided eye.
