162 Laurentia is a large and dark main-belt asteroid that was discovered by the French brothers Paul Henry and Prosper Henry on 21 April 1876, and named after Joseph Jean Pierre Laurent, an amateur astronomer who discovered asteroid 51 Nemausa. An occultation by Laurentia was observed from Clive, Alberta on 21 November 1999. Photometric observations of this asteroid from multiple observatories during 2007 gave a light curve with a period of 11.8686 ± 0.0004 hours and a brightness variation of 0.40 ± 0.05 in magnitude. This is in agreement with previous studies in 1994 and 2007. References External links 000162 Discoveries by Paul Henry and Prosper Henry Named minor planets 000162 000162 000162 18760421
