Overview

162157 (1999 CV8) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1999 CV8 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.

1999 CV8 orbits the sun every 539 days (1.48 years), coming as close as 0.84 AU and reaching as far as 1.75 AU from the sun. Based on its brightness and the way it reflects light, 1999 CV8 is probably between 0.272 to 0.608 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

1999 CV8's spectral type None (Tholen) / V (SMASSII) indicates that it is likely to contain and .

Close Approaches

1999 CV8's orbit is 0.06 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.

1999 CV8 has 14 close approaches predicted in the coming decades:
