2016 DV1
is a near-Earth asteroid estimated to be roughly in diameter. It is a fast rotating asteroid of the Apollo group which was first observed by the Mount Lemmon Survey on 28 February 2016, just days before it passed Earth at 1 lunar distance on 3 March 2016. The elongated fast rotator has a rotation period of 303 seconds. It was recovered in February 2021 as it was about to pass Earth on 3 March 2021 at a distance of.
Orbit
' orbits the Sun at a distance of 0.7–3.0 AU once every 2 years and 6 months. Its orbit has a high eccentricity of 0.63 and an inclination of 3° with respect to the ecliptic. It has an Earth minimum orbital intersection distance of. Due to its eccentric orbit, ' is also a Mars-crosser, crossing the orbit of the Red Planet at 1.66 AU.2016 discovery
It was first observed by the Mount Lemmon Survey on 28 February 2016, when the asteroid was about from Earth and had a solar elongation of 174°. The last optical image was at 3 March 2016 03:08 UT. Bistatic Solar System Radar with DSS-13 and the Green Bank Observatory were used to image the asteroid. It passed closest approach to Earth on 3 March 2016 05:17 UT at a distance of and was quickly approaching the glare of the Sun thus preventing further optical observations.2021 approach
It was recovered on 17 February 2021 by Pan-STARRS when the uncertainty in the asteroid's sky position covered about 1.2° of the sky.By early February 2021 the asteroid was brighter than apparent magnitude 24, which still placed it near the limiting magnitude of even the best automated astronomical surveys. It came to opposition around 26 February 2021 at around magnitude 19. On 3 March 2021 it passed from Earth. It was not listed on the Sentry Risk Table because the line of variation did not pass through where Earth will be.
