Our sun from this system[edit]

Is the Sun the second brightest star in the sky (after Sirius) from this system? Fig (talk) 17:48, 16 March 2013 (UTC)

At the place where this system would be, Sirius is the brightest star, followed by Canopus, followed by Alpha Centauri A, then a number of other stars, and finally the Sun at 1.33m. The Alpha Centauri system is also the closest neighbor at 3.8 to 3.9 light years distance, followed by the Sun at 6.5 ly. Ambi Valent (talk) 22:08, 16 March 2013 (UTC)
  • The Sun has an absolute magnitude of 4.83, which is how bright it would appear at a distance of 32.6 light-years. At a distance of 6.5 light-years the Sun would be 32.62/6.52, or 25.1 times brighter. This would make the Sun (log 25.1x2.512) "3.5 magnitude brighter", resulting it the Sun having an apparent magnitude of roughly 4.83-3.52 = 1.3. Regulus is magnitude 1.35 as seen from Earth. -- Kheider (talk) 14:43, 17 March 2013 (UTC)

Space motion[edit]

Is there anything known about the motion of the Luhman 16 in space? (Movement in the sky was in the article, but not the radial component) Ambi Valent (talk) 22:13, 4 June 2013 (UTC)


Possible Planet[edit]

A planet orbiting one of the two brown dwarfs composing this system has been tentatively identified. See http://arxiv-web3.library.cornell.edu/abs/1312.1303 for a paper titled: "Possible astrometric discovery of a substellar companion to the closest binary brown dwarf system WISE J104915.57-531906.1" — Preceding unsigned comment added by 2601:D:8780:38B:129A:DDFF:FEB0:44D3 (talk) 16:01, 5 December 2013 (UTC)

Jupiter mass[edit]

What is the size of these brown dwarfs relative to the size of Jupiter? 13x? Kortoso (talk) 17:20, 17 December 2013 (UTC)

There are sourced estimated masses in the article: 0.04–0.05 M for A and 0.03–0.05 M for B. Because a solar mass is roughly a thousand Jupiter masses, this is some 40–50 and 30–50 Jupiter masses, respectively. --JorisvS (talk) 12:08, 19 December 2013 (UTC)

WISE 1049-5319Luhman 16 – The name Luhman 16 is being used more in news articles, e.g. the recent planet claims [1] and is also being used in the scientific literature, e.g. the body text of [2] and [3]. The Luhman 16 designation is also far more memorable than the WISE one, even when the latter is abbreviated. 77.57.43.11 (talk) 18:29, 19 December 2013 (UTC)

  • Support. I prefer a name and it seems that "Luhman 16" is increasingly used for this system. --JorisvS (talk) 12:55, 20 December 2013 (UTC)
  • Support. I was already considering moving this to "Luhman 16". Nestrs (talk) 19:40, 20 December 2013 (UTC)
  • Support per WP:NCASTRO; the name Luhman 16 is used more, and is easier to remember. StringTheory11 (t • c) 18:15, 21 December 2013 (UTC)
  • Support. Ruslik_Zero 18:20, 21 December 2013 (UTC)

Iron rainon Luhman 16B[edit]

[4], [5] — Preceding unsigned comment added by 88.66.62.221 (talk) 00:38, 17 March 2014 (UTC)

I've searched both and see no mention of iron rain, or any kind of "precipitation". Just clouds and dust. Huntster (t @ c) 02:03, 17 March 2014 (UTC)
