Lalande 21185 C / L (Brown dwarf) Star Distance to arrival: 125,708 ls

Two stars Lalande 21185 (M2 V) and Betelgeuse (M2 I) are the same spectral type M2, but Betelgeuse is luminosity class I and Lalande 21185 is luminosity class V. This means that Betelgeuse: has much greater size. With a surface temperature of 3828 K, Lalande 21185 has a luminosity that is 0.030 times that of the Sun (calculated assuming a solar surface temperature of 5780 K).

It is located about 8.3 light-years away in the constellation Ursa Major. Closest star to Earth. Lalande 21185 is the fourth nearest star system to the Sun after Alpha Centauri, Barnard's Star, and Wolf 359.Lalande 21185 is located in the southeastern corner of Ursa Major, northwest of Alula Borealis (Nu UMa).It is about three times too faint to be seen with the unaided eye.

•Both found that the color (temperature, spectral type) was related to the luminosity. Because Lalande is a flare star, the star is assumed to be much older than the Sun, making Lalande 21185 approximately 10 billion year s old.
Lalande 21185; The red circle shows the approximate location of Lalande 21185 in Ursa Major. A number of nearby stars – Barnard’s Star, Kapteyn’s Star, Lalande 21185, 61 Cygni, Ross 248 and possibly Procyon – are also included in this class.

Lalande 21185: Here is a link to some basic data on this red dwarf star. Lalande 21185 is also classified as a BY Draconis variable star with the designation of NSV 18593 in the General Catalogue of Variable Stars . Another set of planet names. It's coordinates are (11:03:20.19+35:58:11.55, ICRS 2000.0) . This is because Rigel: has much higher surface temperature. But, that red main sequence stars over many thousands the created by the Ark. A very cool, main sequence red dwarf (M5.8Ve), Wolf 359 is our Sun's dimmest stellar neighbor within 10 ly, with less than 2/100,000th of Sol's visual luminosity. Lalande 21185 Lalande 21185 is a dim red dwarf star which is the fourth closest system to our Sun, after Alpha Centauri, Barnard's Star and Wolf 359. Lalande 21185 C / L (Brown dwarf) Star Distance to arrival: 125,708 ls As it seems to have a luminosity of only 0.025 (two and a half percent of Sol’s), its life zone is a lot closer and narrower, ranging from 0.11 AU on the inside to 0.24 on the outside. Proxima Centauri lies at a distance of 39,900,000,000,000 kilometres, or 271,000 astronomical units, or 4.22 light years.

It is named for its discoverer. Sirius is only the fifth nearest star system to Earth, after Alpha Centauri, Barnard’s Star (5.9 light years), Wolf 359 in Leo (7.8 light years), and Lalande 21185 in Ursa Major (8.3 light years).

Lalande 21185 aka Gliese 441, this nearest star in constellation Ursa Major. Ark have many constructed over the 15,292 BC and established year on the AE 67.
Earth twin distance comes out to 0.16. Facts. In 1970, Castor A and Castor B were separated by less than 2 arcseconds.

•In 1913, Henry Norris Russell did a similar study of nearby stars. Stats: 24 planets, 6 dwarf planets, 4 asteroids and 259 moons
