Lalande 21185 è la sesta stella più vicina alla Terra dopo il sistema triplo di Alpha Centauri, la Stella di Barnard e Wolf 359 ed escludendo il Sole. Estimated Mass: 0.46 × Sol: Luminosity: 0.00568 × Sol: Star charts; Lalande 21185 as seen from Sol. [2]Det finns uppgifter om en obekräftad exoplanet i omloppsbana runt Lalande 21185, GJ 411b. È una stella di magnitudine apparente +7,52 e assoluta di +10,48, e si trova a circa 8,3 al dal sistema solare. Its mass is estimated to be about 46% of the Sun. 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.. This is only an estimate, using the star's spectral type and mass. [1] uzaklıkta yer almakta olup Güneş'e en yakın yıldızlardan biridir. +35deg58m11.5682s - declination. Using data obtained from frequent observations of this star over the last 50 years, University of Pitsburgh astronomer George Gatewood recently announced that much of Lalande 21185's wobble is most likely due to an unseen planet with approximately 90% of the mass of Jupiter and an orbital period of 5.8 years. [6] Yıldız, küçük bir teleskopla görülebilir. Lalande 21185 From Wikipedia the free encyclopedia. Despite this, and although relatively close by, it is (as all red dwarves) very dim, being only magnitude 7.5 in visible light and thus too dim to be seen with the unaided eye.

The next brighter red dwarf further out is Lacaille 9352 (M0.5-1.5 Ve, 0.47 MS, 10.7ly). Of course, it is also important that the to the 46% of the sun and as a result, it can be acceleration and deceleration components are made in a categorized as one of the bigger Red Dwarfs found in way to suit requirements for such a high speed mission our galaxy [5]. Combined with the mass estimate of Lalande 21185, the semimajor axis of this new find is 0.070 AU and Butler et al. [ 7 ] The proportion of elements other than hydrogen and helium is estimated based on the ratio of iron to hydrogen in the star when compared to the Sun. The clearest indication is an excess in the apparent perspective acceleration of the star, detected at two wavelengths in the data gathered with two independent telescopic optical systems and with detectors of two different types. Lalande 21185 (aka BD+36 2147, Gliese 411, HD 95735) is a nearby red dwarf variable star of magnitude 7. calculate an M P sini of 3.8 M E (or Earth masses) – far smaller than any previous exoplanetary claim made for this star. Earth twin distance comes out to 0.16. Contents. 1 Description (Specifications) Lalande 21185 is the largest and brightest of the seven red dwarves within 10 light years of the Sun.
