1566 Icarus is a large near-Earth object of the Apollo group and the lowest numbered potentially hazardous asteroid. It has an extremely eccentric orbit (0.83) and measures approximately 1.4 km (0.87 mi) in diameter. In 1968, it became the first asteroid ever observed by radar. Its orbit brings it closer to the Sun than Mercury and further out than the orbit of Mars, which also makes it a Mercury-, Venus-, and Mars-crossing asteroid. This stony asteroid and relatively fast rotator with a period of 2.27 hours was discovered on 27 June 1949, by German astronomer Walter Baade at the Palomar Observatory in California. It was named after the mythological Icarus.
4197 Morpheus, provisional designation 1982 TA, is a highly eccentric asteroid and near-Earth object of the Apollo group, approximately 3 kilometers in diameter. It was discovered on 11 October 1982, by American astronomers Eleanor Helin and Eugene Shoemaker at Palomar Observatory in California, United States. The asteroid was later named for Morpheus from Greek mythology.
2062 Aten, provisional designation 1976 AA, is a stony sub-kilometer asteroid and namesake of the Aten asteroids, a subgroup of near-Earth objects. The asteroid was named after Aten from Egyptian mythology.
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.
5011 Ptah is a near-Earth object and potentially hazardous asteroid of the Apollo group. It was discovered by astronomers with the Palomar–Leiden survey on 24 September 1960. The rare O-type asteroid on an eccentric orbit measures approximately 1.6 kilometers in diameter. It was named after the Ancient Egyptian deity Ptah.
2340 Hathor, provisional designation 1976 UA, is an eccentric stony asteroid, classified as near-Earth object and potentially hazardous asteroid. It belongs to the Aten group of asteroids and measures approximately 210 meters in diameter. Discovered by Charles Kowal in 1976, it was later named after the ancient Egyptian goddess Hathor.

It was discovered on 6 December 1994, by Scottish–Australian astronomer Robert McNaught at Siding Spring Observatory in Australia. It was one of the first asteroids discovered to have a semi-major axis less than Venus.
6344 P-L is an unnumbered, sub-kilometer asteroid and suspected dormant comet, classified as near-Earth object and potentially hazardous asteroid of the Apollo group that was first observed on 24 September 1960, by astronomers and asteroid searchers Tom Gehrels, Ingrid van Houten-Groeneveld, and Cornelis Johannes van Houten during the Palomar–Leiden survey at Palomar Observatory.
14827 Hypnos is a highly eccentric, sub-kilometer-sized carbonaceous asteroid that is thought to be an extinct comet. It is classified as near-Earth object and potentially hazardous asteroid of the Apollo group.
2061 Anza, provisional designation 1960 UA, is an eccentric asteroid of the Amor group, a subtype of near-Earth objects, estimated to measure approximately 2.7 kilometers in diameter. It was discovered on 22 October 1960, by American astronomer Henry Giclas at Lowell's Flagstaff Observatory in Arizona, United States. The asteroid was later named after Spanish explorer Juan Bautista de Anza.
1580 Betulia, provisional designation 1950 KA, is an eccentric, carbonaceous asteroid, classified as near-Earth object of the Amor group, approximately 4.2 kilometers in diameter. It was discovered on 22 May 1950, by South African astronomer Ernest Johnson at the Union Observatory in Johannesburg. The asteroid was named for Betulia Toro, wife of astronomer Samuel Herrick.
1916 Boreas, provisional designation 1953 RA, is an eccentric, stony asteroid and near-Earth object of the Amor group, approximately 3 kilometers in diameter. After its discovery in 1953, it became a lost asteroid until 1974. It was named after Boreas from Greek mythology.
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.
1777 Gehrels, also designated 4007 P-L, is a stony asteroid from the middle region of the asteroid belt, approximately 13 kilometers in diameter. It was discovered during the Palomar–Leiden survey in 1960, and named for astronomer Tom Gehrels, one of the survey's principal investigators and credited discoverer.
8013 Gordonmoore, provisional designation 1990 KA, is an eccentric, stony asteroid and near-Earth object of the Apollo group, approximately 1–2 kilometers in diameter.
4435 Holt, provisional designation 1983 AG2, is a stony asteroid, sizable Mars-crosser and binary system from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 13 January 1983, by American astronomer Carolyn Shoemaker at the Palomar Observatory in California, United States. It was later named after American astronomer Henry E. Holt. The discovery of its companion was announced in January 2018.

It was discovered on 8 February 1978, by German astronomer Hans-Emil Schuster at ESO's La Silla Observatory in northern Chile. Its orbit is confined between Venus and Mars.
(90075) 2002 VU94 (provisional designation 2002 VU94) is an asteroid on an eccentric orbit, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 2.5 kilometers in diameter. It was discovered on 13 November 2002, by astronomers of the Near-Earth Asteroid Tracking program at Palomar Observatory in California, United States. It is one of the largest potentially hazardous asteroids known.
(154276) 2002 SY50, provisional designation 2002 SY50, 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 (0.7 miles) in diameter. It was discovered on 30 September 2002, by astronomers with the Lincoln Near-Earth Asteroid Research at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States. The K-type asteroid has a rotation period of 4.8 hours. It will make a close encounter with Earth on 30 October 2071.
