# 2020 VV

2020 VV is an Apollo near-Earth asteroid roughly 12 meters (40 feet) in diameter. On 20 November 2020, the asteroid had a 4.4% chance of impacting Earth on 12 October 2033 11:43 UT. As of mid-December 2020, the asteroid has a modest 61 day observation arc. The nominal Earth approach is on 17 October 2033 at a distance of 0.009 AU (1,300,000 km; 840,000 mi), but the line of variations (LOV) is only known with an accuracy of ±22 hours. The line of variations allows the asteroid to come as close as 0.006 AU (900,000 km; 560,000 mi) or pass as far away as 0.01 AU (1,500,000 km; 930,000 mi). With a diameter range of 10–22 meters the asteroid could be as large as the Chelyabinsk meteor.
2020 VV was discovered on 5 November 2020 when it was about 0.036 AU (5,400,000 km; 3,300,000 mi) from Earth and had a solar elongation of 150 degrees. It has a very low 0.35° orbital inclination with respect to the ecliptic plane and an Earth-MOID of only 14,800 km. The asteroid passed Earth on 21 October 2020 at a distance of 0.0215 AU (3,220,000 km; 2,000,000 mi).
Where Earth will be on a given date is known, but given the short observation arc where precisely the asteroid will be on its orbit in 2033 is not. A slight variation in the known orbit of the asteroid can cause the asteroid to be early, right on time (impact solution), or late.
Impact probabilities are calculated independently by Sentry, NEODyS-2 and ESA's Space Situational Awareness Programme. Different models result in slightly different orbit solutions, nominal close approach distances, and impact probabilities. With a long enough observation arc these solutions will converge. In general when the nominal approach is closer to the impact scenario, the odds of impact are greater.
Line of variation (LOV) and different closest approaches :
| Date and time | Nominal closest approach | Position uncertainty | Impact probability on 12 Oct 2033 | Reference |
| 12 October 2033 11:43 | expired impact scenario | ±2.5 hours | | Sentry |
| 17 October 2033 08:57 | 0.0089 AU (1,330,000 km) | 0.000734 AU (109,800 km) | none | ESA |
| 17 October 2033 09:30 | 0.0090 AU (1,350,000 km) | 0.0008398 AU (125,630 km) | none | JPL SBDB |
| 17 October 2033 13:26 | 0.0094 AU (1,410,000 km) | 0.000851 AU (127,300 km) | none | NEODyS-2 |
The line of variation (risk corridor) for 2033 passed over the northeastern USA, Spain, Saudi Arabia, India, and China.
The greatest chances of impact were listed between 17 and 20 November 2020. On 17 November 2020 the Space Situational Awareness Programme listed a 4.2% chance (1 in 24) of impact, Sentry listed a 2.8% chance (1 in 36), and NEODyS-2 listed a cumulative 5.9% chance of impact. By 20 November 2020 with a 15-day observation arc NEODyS-2 listed a 4.4% chance (1 in 23) of impact. At the same time, Sentry listed a 1.3% chance (1 in 77) of impact, and the Space Situational Awareness Programme listed a 1.6% chance (1 in 63).
2020 VV is not categorized as a potentially hazardous object, because the estimated size is significantly smaller than the threshold of about 140 meters for potentially hazardous objects.
