2018 DV1 is a micro-asteroid, classified as a near-Earth object of the Aten group, approximately 6–12 meters (20–40 feet) in diameter.

Contrary to the much larger Apollos, Atens have a semi-major axis of less than 1 AU, that is, a period less than a year (Earth).

[5] 2018 DV1 has a notably low minimum orbital intersection distance with Earth of 23,800 km (0.000159 AU), or 0.06 LD.

It closest future approach is predicted to occur on 28 February 2064, then at a nominal distance of 24 LD (0.0628 AU).

[2] Based on a generic magnitude-to-diameter conversion, 2018 DV1 measures between 6 and 12 meters in diameter, for an absolute magnitude of 28.4, and an assumed albedo between 0.057 and 0.20, which represent typical values for carbonaceous and stony asteroids, respectively.
