2019 TF7 is an asteroid from the inner regions of the asteroid belt, approximately 800 meters (0.50 miles) in diameter. It was discovered on 7 October 2019 and with the orbital uncertainty still high after 4 days of observation, it had the rare chance of impacting Earth in less than 2 years on 26 June 2021. The line of variation (LOV) was 730 million km long and overlapped Earth's position. It was listed at the top of the European Space Agency risk list due to its large size and near-term threat. Precovery images from 18 September 2019 were located, extending the observation arc to 23 days, and the object was removed from the Sentry Risk Table. On 26 June 2021 the asteroid will be 4.9 AU (730 million km) from Earth.
