(719) Albert is an asteroid of the Cupid type , a group of asteroids whose orbits can cross the earth's orbit . Albert was discovered by Johann Palisa at the Vienna University Observatory on October 3, 1911 - as the second of this class of minor planets, the first to be found on August 13, 1898 by Gustav Witt (433) Eros at the Berlin Urania observatory.
It was named in honor of Baron Albert Freiherr von Rothschild , one of the supporters of the observatory. However, the asteroid was lost again and was only rediscovered in 2000 by scientists from the Spacewatch team at the University of Arizona and identified by Gareth Vaughan Williams. Its size is estimated at two to four kilometers. Albert approaches the earth about every 30 years and can get 30 million kilometers to it.
