Overview

2020 DC is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 DC 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.

2020 DC orbits the sun every 736 days (2.02 years), coming as close as 1.00 AU and reaching as far as 2.19 AU from the sun. Based on its brightness and the way it reflects light, 2020 DC is probably between 0.008 to 0.035 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2020 DC's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2020 DC has 9 close approaches predicted in the coming decades:

Images and Observations

2020 DC's orbit is determined by observations dating back to Feb. 16, 2020. It was last officially observed on March 25, 2022. The IAU Minor Planet Center records 128 observations used to determine its orbit.

Accessibility and Exploration

2020 DC can be reached with a journey of 378 days. This trajectory would require a delta-v of 9.769 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 1,411 potential trajectories and launch windows to this asteroid.
