Overview
208115 (2000 CT101) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2000 CT101 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2000 CT101 orbits the sun every 541 days (1.48 years), coming as close as 0.84 AU and reaching as far as 1.76 AU from the sun. Based on its brightness and the way it reflects light, 2000 CT101 is probably between 0.181 to 0.404 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
Close Approaches
2000 CT101's orbit is 0.01 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 CT101 has 9 close approaches predicted in the coming decades:
