A kilometre (American spelling: kilometer) (symbol: km) is a unit of length equal to 1000 metres (from the Greek words khilia = thousand and metro = count/measure). ... In astronomy, a rotation period is the time an astronomical object takes to complete one revolution around its rotation axis. ... The hour was originally defined in Egypt as 1/24 of a day, based on their duo-decimal numbering system (which counted finger joints on each hand). ... In astronomy the term spectral class refers to classifying objects according to their spectral lines, which indicate an objects chemical composition. ... In astronomy, absolute magnitude is the apparent magnitude, m, an object would have if it were at a standardized distance away. ... The albedo is a measure of reflectivity of a surface or body. ...

It was discovered by brothers Paul Henry and Prosper Henry on April 21, 1876 and named after A. Laurent, an amateur astronomer who discovered asteroid 51 Nemausa. Paul-Pierre Henry (Paul Henry) (August 21, 1848 – January 4, 1905) and his brother Mathieu-Prosper Henry (Prosper Henry) (December 10, 1849 – July 25, 1903) were French opticians and astronomers. ...
