History
The celestial coordinates of Lalande 21185 were first published in 1801 by French astronomer Jérôme Lalande of the Paris Observatory in the star catalog, Histoire Céleste Française. The catalog sequence numbers for all of the observed stars, including this one, were added to the original catalog by a later editor in an 1847 republication. Today this star, along with a few others, is still commonly referred to by its Lalande catalog number.
Winneke is reported to have made the first measurement of the star's parallax of .511 arc seconds in 1856 and thus first identifying Lalande 21185 as the second-closest known star to the Sun, after the Alpha Centauri system. Since that time better measurements have placed the star further away but it was the still the second-closest known star system until the discovery of two dim red dwarf stars, Wolf 359 and Barnard's Star, in the early twentieth century using astrophotography.

Famous quotes containing the word history:
“... that there is no other way,
That the history of creation proceeds according to
Stringent laws, and that things
Do get done in this way, but never the things
We set out to accomplish and wanted so desperately
To see come into being.”
—John Ashbery (b. 1927)
“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (18181883)
“In history an additional result is commonly produced by human actions beyond that which they aim at and obtainthat which they immediately recognize and desire. They gratify their own interest; but something further is thereby accomplished, latent in the actions in question, though not present to their consciousness, and not included in their design.”
—Georg Wilhelm Friedrich Hegel (17701831)
