Distance

Hello Bright Lights, The Lalande 21185 page lists (in the text) a distance of 8.21 light years. The table shows 8.29 light years. I have a feeling the 8.21 l.y. reference is the correct one -- only because the Apparent Magnitude listed (7.47), if it was at 8.21 l.y., matches the corresponding 10.46 Absolute Magnitude. Given its luminance, if Lalande was at 8.29 l.y., an Absolute Magnitude would resolve to 7.49 Apparent Magnitude. The page for the "List of nearest stars" indicates the 8.29 l.y. value (but that page tends to have several values that differ from the values on the corresponding detail pages). So, I'm not sure which is the correct distance. Thanks, Tesseract 501@aol.com (August 20, 2005)

The article lists this as the 4th closest star to our sun, but aren't all these closer: Alpha Centauri C, Alpha Centauri A, Alpha Centauri B, Barnard's Star and Wolf 359

________ Answer: Lalande 21185 is the fourth closest STAR SYSTEM. Comment: The planets around Lalande 21185 have never been published and are suspect....

Copyright problems

In this revision, material copied from the copyrighted website SolStation (specifically this page) was added to the article. Per WP:CP I reverted the article to the version before the copyrighted material was added. Icalanise (talk) 21:26, 17 October 2008 (UTC)

I had to revert the article again because more material copied from SolStation was added in this revision. There are several instances where the text added in the revision was the same as SolStation's, with a couple of substituted words. Icalanise (talk) 12:26, 18 October 2008 (UTC)

Removed planetary system section

I've removed the planetary system section. I don't think this should be restored until it comes with some legitimate references (at least one paper in a refereed journal, and an entry in a notable database, like the Extrasolar Planets Encyclopaedia. — Aldaron • T/C 17:04, 29 May 2009 (UTC)

Flare star evidence

I have removed the statements and category identifying this star as a flare star from the article as this is not supported by the primary references. SIMBAD and VizieR list this star as a flare star but this does not seem to be consistent with their two primary references. One reference lists this star in a table as an example of a quiet star of this variable type and the other reference does not mention this star specifically at all. My guess is the information is automatically harvested from the articles and is not carefully reviewed. This is a rather important factor considering the effect flaring events would have on any planets that may be in the habitable zone of this nearby star.

A mistake in the map?

The red circle in the infobox map locates the star into the Leo Minor constellation (not Ursa Major). A mistake? --Vachovec1 (talk) 21:48, 29 November 2015 (UTC)

Good catch! I've attempted to rectify the chart. Praemonitus (talk) 18:55, 30 November 2015 (UTC)
