22 years ago (January 7, 1976) Eleanor "Glo" Helin discovered asteroid 2062 Aten with the Palomar 18-inch Schmidt.
Aten was the first asteroid found that orbits almost entirely inside Earth’s orbit. As such Aten defined a new class of asteroids. Its semi-major axis (roughly the average distance from the Sun) is smaller than Earth's. In mythology Aten is the Egyptian god of the Sun.
Astronomers made radar measurements with the Goldstone antenna in 1995 to determine its diameter (0.9 km) and found that Aten has an unusually long period of rotation - nearly 41 hours.
