162 Laurentia is a large and darkmain-beltasteroid that was discovered by the French brothersPaul Henry and Prosper Henry on 21 April 1876, and named afterJoseph Jean Pierre Laurent, an amateur astronomer who discovered asteroid51 Nemausa.
Anoccultation by Laurentia was observed fromClive, Alberta on 21 November 1999.[citation needed]
Photometric observations of this asteroid from multiple observatories during 2007 gave alight curve with a period of 11.8686 ± 0.0004 hours and a brightness variation of 0.40 ± 0.05 inmagnitude. This is in agreement with previous studies in 1994 and 2007.[4]
