2017 XX61 is a small near-Earth object, approximately 17 meters (56 feet) in diameter that follows an eccentric orbit. This Apollo asteroid was first observed on 15 December 2017, by astronomers of the Mount Lemmon Survey at Mount Lemmon Observatory near Tucson, Arizona. It transited Earth at 8 lunar distances on 18 December 2017 at 14:54 UTC, and was lost on the following night. As of 2020, it has not been recovered.
(585310) 2017 YZ1, provisional designation: 2017 YZ1, is a sub-kilometer asteroid on an eccentric orbit, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 250 meters (800 feet) in diameter. It was first observed on 20 December 2017, by astronomers with the Mount Lemmon Survey at Mount Lemmon Observatory near Tucson, Arizona, in the United States. On 29 January 2018, it passed Earth at 125 lunar distances.
2018 AH is a sub-kilometer asteroid, classified as near-Earth object of the Apollo group, approximately 100 m (300 ft) in diameter. It was first observed on 4 January 2018, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) on Mauna Loa and quickly followed-up by many other surveys, with precovery observations found from Pan-STARRS and PTF from the day previous.
2018 CN2 is a very small asteroid, classified as a near-Earth object of the Apollo group, approximately 5 to 16 meters in diameter. It was first observed by astronomers of the Mount Lemmon Survey at Mount Lemmon Observatory, Arizona, on 8 February 2018, one day prior its close encounter with Earth at 0.18 lunar distances.
2018 CF2 is a micro-asteroid and near-Earth object of the Apollo group on an eccentric orbit with has an estimated 4–15 meters (10–50 ft). It was first observed on 7 February 2018, by astronomers of the Mount Lemmon Survey at Mount Lemmon Observatory, Arizona, United States. The discovery occurred the day after its sub-lunar passage as it approached the Earth from a sunward direction, and this flyby altered the asteroid's orbit slightly.
2018 BD is a small asteroid and near-Earth object of the Apollo group, approximately 2–6 meters (7–20 ft) in diameter. It was first observed on 18 January 2018, by astronomers of the Catalina Sky Survey at Mount Lemmon Observatory, Arizona, United States, just hours before passing about 0.10 lunar distances from the Earth.
2018 GE3 is a sub-kilometer asteroid on a highly eccentric orbit, classified as a near-Earth object of the Apollo group, approximately 48–110 meters (160–360 feet) in diameter. It was first observed on 14 April 2018, by astronomers with the Catalina Sky Survey one day prior to its sub-lunar close encounter with Earth at 0.5 lunar distance. It is one of the largest known asteroids (possibly the largest) in observational history to ever pass that close to Earth (also see list).
(85182) 1991 AQ is a stony asteroid on a highly eccentric orbit, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 1.1 kilometers in diameter. It was discovered on 14 January 1991, by American astronomer Eleanor Helin at the Palomar Observatory in California. Based on its brightness variation of 0.69 magnitude, this Q-type asteroid is likely elongated. It belongs to the small group of potentially hazardous asteroids larger than one kilometer.
2018 PD20 is a small asteroid, classified as a near-Earth object of the Apollo group, approximately 9–20 meters (30–66 feet) in diameter. On 11 August 2018, it was first observed by ATLAS at the Mauna Loa Observatory on Hawaii (T08), when it passed 33,500 kilometers (20,800 miles) from the Earth. This is notable because it came within a tenth of the lunar distance, or 0.10 LD which is closer to Earth than satellites in a geostationary orbit. These have an altitude of 0.11 LD, about 36,000 km (22,000 mi), approximately 3 times the width of the Earth.
2019 AS5 is a near-Earth asteroid that passed close by the Earth on 8 January 2019. It passed within 0.04 lunar distances or 15,000 kilometers of the center of the Earth, 8600 km from the surface. It was discovered by the Mt. Lemmon Survey 9 hours after closest approach. It is estimated to be about 1–2 metres (3–7 feet) in diameter.
2019 BZ3 is a very small near-Earth asteroid of the Apollo group, approximately 6 meters (20 feet) in diameter. It was first observed by the Mount Lemmon Survey on 28 January 2019, just hours after the asteroid's sub-lunar flyby of Earth at less than 0.12 lunar distance.
