Photographic coverage of about 80,000 sq deg of sky with the Palomar 46-cm Schmidt camera has yielded 12 new planet-crossing asteroids as well as many objects in the main asteroid belt. The estimated population of planet-crossing asteroids includes approximately 100 Atens, 700 + or- 300 Apollos, 1000-2000 Amors, 10,000 + or- 5000 Mars crossers, and approximately 5000 Mars grazers.
