Lumen ( minor planet designation: 141 Lumen) is a carbonaceous asteroid from the intermediate

asteroid belt The asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies, of many sizes, but much smaller than planets, c ...

It was discovered on January 13, 1875, by the brothers

Paul Henry and Prosper Henry Paul-Pierre Henry (Paul Henry) (21 August 1848 – 4 January 1905) and his brother Prosper-Mathieu Henry (Prosper Henry) (10 December 1849 – 25 July 1903) were French opticians and astronomers. They made refracting telescopes and instruments ...

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. 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.Lightcurve Results
