141 Lumen is a dark, large rocky asteroidAn asteroid is a small, solid object in our Solar System, orbiting the Sun. An asteroid is an example of a minor planet (or planetoid , which are much smaller than planets. The asteroids are believed to be remnants of the protoplanetary disc which were no 135 km in diameter (about the size of the island of Puerto RicoThe Commonwealth of Puerto Rico ("Estado Libre Asociado de Puerto Rico") is a self-governing unincorporated organized territory of the United States located in the northeastern Caribbean, east of the Dominican Republic. Puerto Rico, the smallest of the Gr) near the inner edge of the Main belt within the Eunomia family of asteroids. It is not, however, physically related to the group.
Its orbital speed is more than 1,000 km/ h.
It was discovered on January 13, 1875 by the brothers Paul Henry and Prosper Henry, but Paul is one who was given the credit for this discovery. It is named after Lumen: Récits de l'infini , a book by the astronomer Camille Flammarion.
