Episode: 91E-103-Small Asteroids In Earth-like Orbits
Description: Four days after it made its closest approach to Earth, I found a 10 foot diameter asteroid with the NASA funded University of Arizona 60 inch telescope on Mt. Lemmon. At that point it was 838,000 miles from us and was moving away at about 3 miles/second. Previously, It had been about half the distance to the Moon from planet Earth. This small asteroid orbits the Sun every 349 days on a path which crosses our orbit twice a year. Calculations by the NASA - JPL group indicate that it can come within 2 Earth diameters of us.
