162 Laurentia is a large and dark main-belt asteroid that was discovered by the French brothers Paul Henry and Prosper Henry on April 21, 1876, and named after A. Laurent, an amateur astronomer who discovered asteroid 51 Nemausa.
An occultation by Laurentia was observed from Clive, Alberta on November 21, 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.[2]
