719 Albert, provisional designation 1911 MT, is a stony asteroid and prolific lost minor planet for 89 years, classified as near-Earth object of the Amor group of asteroids, approximately 2.5 kilometers in diameter. It was discovered by Austrian astronomer Johann Palisa at the Vienna Observatory on 3 October 1911. The asteroid was named in memory of Albert Salomon Anselm von Rothschild, an Austrian philanthropist and banker. After 433 Eros it was the second discovery of an Amor asteroid.
Albert orbits the Sun at a distance of 1.2–4.1 AU once every 4 years and 3 months (1,567 days). Its orbit has an eccentricity of 0.55 and an inclination of 12° with respect to the ecliptic. The asteroids first observation is a precovery taken in September 1911 at Heidelberg Observatory, two weeks prior to its discovery at Vienna. The body's observation arc begins the night following its official discovery observation.Albert is also a Mars-crossing asteroid.
The asteroid has a minimum orbital intersection distance with Earth of 0.2030 AU (30,400,000 km), which translates into 79.1 lunar distances. On 8 September 1911, shortly before its discovery, it made its closest approach at 0.2054 AU (30,700,000 km). After another close encounter in 1941, Albert will not approach Earth to a similar distance until 2078.
