Lalande 21185. Lalande 21185; The red circle shows the approximate location of Lalande 21185 in Ursa Major. Lalande 21185 b; Lalande 21185 b is an exoplanet orbiting the star Lalande 21185, located about 8.3 light-years ( 2.5 pc) away from Solar System. 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). From Infogalactic: the planetary knowledge core.

The star is a red dwarf with a spectral luminously M2.1 Vne and only contains about 40% of the mass of our own star. Modelling suggests that the star has a mass 0.46 times that of the Sun making Lalande 21185 rather large among red dwarfs.

Only a Centauri distant 4.3 light years, and Barnard's star distant 6.0 light years are known to be definitely nearer than Lalande 21185, Wolf 359 and L726-8. The latter three stars vie at present for third place in order of stellar distance; about 8 light years. This is only an estimate, using the star's spectral type and mass. ... GJ 411 ist ein Roter Zwerg mit nur rund 40 Prozent der Masse unserer Sonne. Lalande 21185 is the closest system to Sol after Proxima Centauri, Alpha Centauri, Barnard's Star, and Wolf 359.Located in the constellation of Ursa Major, it is only 8.3 light years away, although due to its low apparent magnitude of 7.5, it's invisible to the unaided eye.. Lalande (vom französischen la lande für „das Moor“) steht für: . Lalande 21185 Iron Abundance is -0.30 with an error value of 0.05 Fe/H with the Sun has a value of 1 to put it into context. Lalande 21185, dim red dwarf M2V: Star mass, radii: 0.23, 0.35 x Sol: Notes:-Hypothetical planet location: 0.08 AU: Possible life: 5% .

The following plot shows the approximate location of the planets in this system with respect to the habitable zone (green) and the size of the star (red). Lalande 21185 ist ein schwacher roter Zwergstern, vergleichbar mit Gliese 623 A (M2.5V) und B (M5.8Ve) der ein wenig schwächer ist. using the Palomar Testbed Interferometer in 1999 and 2000 combined with the best distance measurements indicates that Lalande 21185 has a radius 0.393 times that of the Sun. Direct measurements of the angular diameter by Lane et al. Der Durchmesser des Sternes beträgt auch nur ca. The value comes from the Hipparcos Extended Catalog.

Its discovery was publicly announced on 2017. Februar 2017. Lalande 21185 ist, wie die meisten Sterne in unserer unmittelbaren stellaren Umgebung, ebenfalls ein Roter Zwerg. Seine Spektralklasse ist M 2, und damit ist Lalande 21185 weit leuchtstärker als beispielsweise Wolf 359 oder Barnards Pfeilstern . mass = 0.46 radius = 0.46 gravity = luminosity = 0.0016 temperature = 3,400 metal = 63% Sun rotation = age = 5-10 × 10 9 Starbox catalog names = BD+36 2147, G 119-052, Gliese 411, HD 95735, HIP 54035, LFT 756, LHS 37, LTT 12960, MCC 594, PLX 2576, SAO 62377Starbox reference Simbad = HD+95735 ARICNS = Lalande 21185, often abbreviated as LAL 21185, is a red dwarf star … 35% desjenigen der Sonne und … Elle se trouve dans la constellation de la Grande Ourse.
