4769 Castalia is a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 1.4 kilometers in diameter and was the first asteroid to be modeled by radar imaging. It was discovered on 9 August 1989, by American astronomer Eleanor Helin (Caltech) on photographic plates taken at Palomar Observatory in California. It is named after Castalia, a nymph in Greek mythology. It is also a Mars- and Venus-crosser asteroid.
1221 Amor is an asteroid and near-Earth object on an eccentric orbit, approximately 1 kilometer (0.6 miles) in diameter. It is the namesake of the Amor asteroids, the second-largest subgroup of near-Earth objects. It was discovered by Eugène Delporte at the Uccle Observatory in 1932, the first time that an asteroid was seen to approach Earth so closely. The assumed S-type asteroid is one of few low-numbered asteroids for which no rotation period has been determined. It was assigned the provisional designation 1932 EA1 and named for Cupid, also known as "Amor" in Latin, the Roman equivalent of the Greek god Eros.
4581 Asclepius, provisional designation 1989 FC, is a sub-kilometer-sized asteroid, classified as near-Earth object and potentially hazardous asteroid of the Apollo group that makes close orbital passes with Earth. Discovered on 31 March 1989 by American astronomers Henry Holt and Norman Thomas at Palomar Observatory, Asclepius is named after the Greek god of medicine and healing.
887 Alinda is a very eccentric, near-Earth asteroid with an Earth minimum orbit intersection distance (MOID) of 0.092 AU. It is the namesake for the Alinda group of asteroids and measures about 4 kilometers in diameter. The stony S-type asteroid was discovered by German astronomer Max Wolf at Heidelberg Observatory on 3 January 1918.
2202 Pele, provisional designation 1972 RA, is an eccentric asteroid and near-Earth object of the Amor group, approximately 1–2 kilometers in diameter.
1864 Daedalus, provisional designation 1971 FA, is a stony asteroid and near-Earth object of the Apollo group, approximately 3 kilometers in diameter. It was discovered on 24 March 1971, by Dutch–American astronomer Tom Gehrels at Palomar Observatory, California, and named after Daedalus from Greek mythology.
37655 Illapa is a carbonaceous asteroid, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 1.5 kilometers in diameter. It was discovered, on 1 August 1994, by American astronomer couple Carolyn and Eugene Shoemaker at the Palomar Observatory in California, United States.
4947 Ninkasi, provisional designation 1988 TJ1, is a sub-kilometer asteroid, classified as near-Earth object of the Amor group, approximately 520 meters in diameter. It was discovered on 12 October 1988, by American astronomer Carolyn Shoemaker at Palomar Observatory in California.
4544 Xanthus, provisional designation 1989 FB, is an asteroid, classified as near-Earth object of the Apollo group, approximately 1.3 kilometers in diameter. It was discovered on 31 March 1989, by astronomers Henry Holt and Norman Thomas at the Palomar Observatory in California.
(6491) 1991 OA is a highly eccentric, stony asteroid, classified as near-Earth object and potentially hazardous asteroid, approximately half a kilometer in diameter. It was discovered on 16 July 1991, by American astronomer Henry E. Holt at the U.S. Palomar Observatory in California.
(153814) 2001 WN5 is a sub-kilometer asteroid, classified as near-Earth object and potentially hazardous asteroid of the Apollo group.
2011 CQ1 is a meteoroid discovered on 4 February 2011 by Richard A. Kowalski, at the Catalina Sky Survey. On the same day the meteoroid passed within 0.85 Earth radii (5,480 kilometers (3,410 mi)) of Earth's surface, and was perturbed from the Apollo class to the Aten class of near-Earth objects. With a relative velocity of only 9.7 km/s, had the asteroid passed less than 0.5 Earth radii from Earth's surface, it would have fallen as a brilliant fireball. The meteoroid is between 80 centimeters (31 in) and 2.6 meters (100 in) wide. The meteoroid was removed from the Sentry Risk Table on 5 February 2011.
(8014) 1990 MF is a sub-kilometer near-Earth object and potentially hazardous asteroid in the Apollo group. It was discovered by American astronomer Eleanor Helin at the Palomar Observatory in California on 26 June 1990. The asteroid measures approximately 0.7 kilometers in diameter. On 23 July 2020, it came within 0.055 AU of the Earth—about 21 times the Moon's distance.
2013 PJ10 is a Near-Earth asteroid that was discovered on 4 August 2013 in Observatorio Astronómico de La Sagra, with an estimated diameter of about 50 meters. At 02.18 GMT, 4 August 2013, this asteroid flew at a minimum distance from the Earth (371.4 thousand kilometers), accounting for 0.96 average radius of the lunar orbit, but until 2180 it will not approach the Earth closer than 3.2 million miles.
2014 SC324 is a sub-kilometer asteroid and fast rotator, classified as a near-Earth object of the Apollo group, approximately 50 meters in diameter. It was first observed on 30 September 2014, by the Mount Lemmon Survey at an apparent magnitude of 21 using a 1.5-meter (59 in) reflecting telescope. With an absolute magnitude of 24.3, the asteroid is about 37–85 meters in diameter.
(85989) 1999 JD6 (provisional designation 1999 JD6) is an Aten asteroid, near-Earth object, and potentially hazardous object in the inner Solar System that makes frequent close approaches to Earth and Venus. On the Earth approach in 2015, it was observed by the Goldstone Solar System Radar and found to be a contact binary with the largest axis approximately 2 kilometers wide, and each lobe about 200–300 meters large. Although 1999 JD6 in its current orbit never passes closer than 0.047 AU to Earth, it is listed as a potentially hazardous object because it is large and might pose a threat in the future.
(549948) 2011 WL2 is a sub-kilometer asteroid, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group. It was discovered on 16 November 2011, by astronomers with the LINEAR at the Lincoln Laboratory ETS near Socorro, New Mexico, in the United States.
11885 Summanus is a dark asteroid and large near-Earth object of the Apollo group. It was discovered by astronomers with the Spacewatch programm at Kitt Peak Observatory on 25 September 1990. The object has a rotation period of 7.3 hours and measures approximately 1.3 kilometers in diameter. It was named after Summanus, the Roman deity of nocturnal lightning and thunder.
2012 TV is a near-Earth Apollo asteroid with an estimated diameter of 30 metres (98 ft). Its closest approach to the Earth was on October 7, 2012, with a distance of 0.0017 astronomical units. It also approached the Moon an hour earlier with a distance of 0.0028 astronomical units. With a short observation arc of 1.8 days, the asteroid is listed on the Sentry Risk Table and has a 1:500,000 chance of impacting Earth on April 2, 2081.
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.
