What was discovered

Helin discovered 2062 Aten, a near-Earth asteroid with a semi-major axis under 1 AU and an aphelion above 0.983 AU, which gave its name to an entire new dynamical class of near-Earth asteroids. Today nearly 3,000 Aten-type asteroids have been catalogued, several of them potentially hazardous.

What it led to

  • Dynamical classification of Aten-type asteroids
  • Cataloguing of thousands of near-Earth objects
  • Planetary defense programs

Built on

  • Near-Earth asteroid search programs
