2023 DM

Key Facts

• Categorized as a Apollo-class Asteroid
• Comparable in size to a school bus or smaller
• Will pass within 3,256,230 km of Earth in 2023
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

2023 DM is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2023 DM 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.

2023 DM orbits the sun every 751 days (2.06 years), coming as close as 0.97 AU and reaching as far as 2.26 AU from the sun. Based on its brightness and the way it reflects light, 2023 DM is probably between 0.032 to 0.142 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2023 DM'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.

2023 DM has 2 close approaches predicted in the coming decades:

Images and Observations

2023 DM's orbit is determined by observations dating back to Feb. 19, 2023. It was last officially observed on March 19, 2023. The IAU Minor Planet Center records 238 observations used to determine its orbit.

Accessibility and Exploration

2023 DM can be reached with a journey of 426 days. This trajectory would require a delta-v of 11.628 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 55 potential trajectories and launch windows to this asteroid.
