2062 Aten is an asteroidAn asteroid is a small, solid object in our Solar System, orbiting the Sun. An asteroid is an example of a minor planet (or planetoid , which are much smaller than planets. The asteroids are believed to be remnants of the protoplanetary disc which were no that was discovered at the Palomar Mountain Observatory by Eleanor F. Helin, who is now the principal scientist for the NEAT (Near-Earth Asteroid Tracking) project. Aten was the first asteroid found to have a semi-major axisIn geometry, the semi-major axis (also semimajor axis a applies to ellipses and hyperbolas. Ellipse The semi-major axis of an ellipse is one half of the major axis running from the center, through a focus, and to the edge of the ellipse. The major axis is of less than one astronomical unit. A new category of asteroids was thus created, the Atens, of which 16 are known and numbered, and some 212 awaiting numbering as of July 2004, ranging from 1989 VA to 2004 MD6 .
