Overview

68347 (2001 KB67) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2001 KB67 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2001 KB67 orbits the sun every 345 days (0.94 years), coming as close as 0.60 AU and reaching as far as 1.33 AU from the sun. Based on its brightness and the way it reflects light, 2001 KB67 is probably between 0.291 to 0.652 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to the U.S. Capitol building.

The rotation of 2001 KB67 has been observed. It completes a rotation on its axis every 6.35 days.

Close Approaches

2001 KB67's orbit is 0.01 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2001 KB67 has 13 close approaches predicted in the coming decades:
