Asteroid 719 Albert Closest Approach To Earth (3.075 AU)
Closest Approach to Earth - This happens as a heavenly body has an orbit that somewhere is closest to Earth. Most Astroids and Comets have an elliptical orbit in relation to a star (ie the Sun) or planet and thus will vary in distance to Earth.
