Talk:Gliese 445

40,000 years

Is 40,000 years an error given that AC+79 3888 is 17 ly or so & on the Voyager I wiki-page it states that if Voyager 1 were traveling in the direction of the nearest star, (ie. Proxima & Alpha Centuari 4.2-3 ly) it would arrive in about 75,000 years? 75,000 years to 4.3 ly & 40,000 to 16? Doesn't add up does it - do you mean 400,000 years instead? 124.182.98.146 (talk) 04:57, 16 March 2010 (UTC) StevoRaine

NASA's 40,000 years is correct. You need to account for the fact that AC+79 3888 is approaching the Sun and that in roughly 46 thousand years AC+79 3888 will only be 1.05 parsecs (3.45 light-years) away. -- Kheider (talk) 21:36, 20 March 2010 (UTC)

When Voyager 1 passes AC+79 3888, will AC+79 3888 still be in Camelopardalis, and if not, where? The Article should say. It could give the approximate RA & Dec of AC+79 3888, and of Voyager, at that time - NASA should know. Also, how near to the Sun will AC+79 3888 get, how bright, when, and in which direction? 94.30.84.71 (talk) 13:11, 16 June 2011 (UTC)

Possible Collision?

Reading this article and the fact that this star is coming towards the sun made me wonder whether there is a possibility of a collision with the sun. Since such a big and catastrophic thing would be mentioned in the article, then I suppose there is no chance of that? Is there any chance of the orbits of the planets being affected by this star passing so close (unless 3.45ly isn't really that close...) 74.83.233.1 (talk) 16:53, 15 May 2010 (UTC)

For a M dwarf star, 3 light-years is not dangerously close. Gliese 710 is more massive and will pass within ~1 light-year. -- Kheider (talk) 18:32, 15 May 2010 (UTC)

Diagram request

I wonder if anyone with the time and knowledge would be willing to produce a diagram showing this star's trajectory in relation to the sun so we can see how close it will come relative to Proxima Centauri, the Oort Cloud and so on. Same goes for other stars that have had or will have solar encounters. Will there be a gravity assist when it goes past - i.e. will it or the sun's trajectory through the galaxy be altered enough that a diagram would have a curved rather than straight line?

Gl 445 → Gliese 445 – Wikipedia pages for stars in the Gliese catalog are named using the full name (Gliese) rather than the shorthand code (GJ or Gl). An attempt to move the page failed, so an administrator is needed. Metebelis (talk) 05:21, 23 February 2012 (UTC)

Proxima Camelopardalis?

Dodgy-looking name from a not-very-reliable-looking web page. Lithopsian (talk) 13:53, 8 August 2016 (UTC)
