Overview

138013 (2000 CN101) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 CN101 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2000 CN101 orbits the sun every 738 days (2.02 years), coming as close as 0.58 AU and reaching as far as 2.61 AU from the sun. 2000 CN101 is about 3.5 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

Close Approaches

2000 CN101's orbit is 0.11 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2000 CN101 has 10 close approaches predicted in the coming decades:
