824 Anastasia is a main belt asteroid orbiting the Sun. It is approximately 34.14 km in diameter.[1] It was discovered on March 25, 1916, by Grigory Neujmin at Simeiz Observatory in Russian Empire.[1][2] It is named in memory of Anastasia Semenoff, an acquaintance of the discoverer.[3]

Occultation[edit]

On April 6, 2010, 824 Anastasia had the distinction of causing the brightest asteroid occultation ever predicted for North America for an asteroid of its size. The asteroid occulted the naked-eye star ζ Ophiuchi over a path stretching from the Los Angeles area to Edmonton, Alberta.[4][5][6]
