Editing 141 Lumen (section)

== Description ==

It was discovered on January 13, 1875, by the brothers [[Paul Henry and Prosper Henry]], but Paul is the one who was given the credit for this discovery. It is named for ''[[Lumen: Récits de l'infini]]'', a book by the astronomer [[Camille Flammarion]].<ref>Schmadel Lutz D.

[[Richard P. Binzel|Richard Binzel]] and [[Schelte J. Bus|Schelte Bus]] further added to the knowledge about this asteroid in a light-curve survey published in 2003. This project was known as Small Main-belt Asteroid Spectroscopic Survey, Phase II or SMASSII, which built on a previous survey of the main-belt asteroids. The visible-wavelength (0.435–0.925 micrometre) spectra data was gathered between August 1993 and March 1999.<ref>Bus, S., Binzel, R. P. ''Small Main-belt Asteroid Spectroscopic Survey, Phase II''.

Lightcurve data has also been recorded by observers at the Antelope Hill Observatory, which has been designated as an official observatory by the [[Minor Planet Center]].<ref>{{Cite web |url=http://www.antelopehillsobservatory.org/index_files/Page334.htm |title=Lightcurve Results<!-- Bot generated title --> |access-date=9 March 2008 |archive-date=25 July 2011 |archive-url=https://web.archive.org/web/20110725043437/http://www.antelopehillsobservatory.org/index_files/Page334.htm |url-status=dead }}</ref>
