Overview

6611 (1993 VW) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1993 VW 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.

1993 VW orbits the sun every 807 days (2.21 years), coming as close as 0.87 AU and reaching as far as 2.52 AU from the sun. 1993 VW is about 1.4 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. Pentagon.

The rotation of 1993 VW has been observed. It completes a rotation on its axis every 2.56 hours.

1993 VW's spectral type None (Tholen) / V (SMASSII) indicates that it is likely to contain and .

Close Approaches

1993 VW's orbit is 0.06 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.
