Overview

11405 (1999 CV3) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1999 CV3 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 CV3 orbits the sun every 644 days (1.76 years), coming as close as 0.88 AU and reaching as far as 2.03 AU from the sun. 1999 CV3 is about 3.6 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the island of Manhattan.

The rotation of 1999 CV3 has been observed. It completes a rotation on its axis every 6.50 hours.

1999 CV3's spectral type None (Tholen) / Sq (SMASSII) indicates that it is likely to contain and .

Close Approaches

1999 CV3's orbit is 0.12 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 CV3 has 5 close approaches predicted in the coming decades:
