Overview

2011 DV is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2011 DV as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2011 DV orbits the sun every 342 days (0.94 years), coming as close as 0.91 AU and reaching as far as 1.00 AU from the sun. Based on its brightness and the way it reflects light, 2011 DV is probably between 0.128 to 0.571 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.

Close Approaches

2011 DV's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2011 DV has 14 close approaches predicted in the coming decades:

Images and Observations

2011 DV's orbit is determined by observations dating back to Feb. 22, 2011. It was last officially observed on March 30, 2023. The IAU Minor Planet Center records 133 observations used to determine its orbit.

Accessibility and Exploration

2011 DV can be reached with a journey of 370 days. This trajectory would require a delta-v of 6.584 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 103,557 potential trajectories and launch windows to this asteroid.
