2063 Bacchus, provisional designation 1977 HB, is a stony asteroid and near-Earth object of the Apollo group, approximately 1 kilometer in diameter. The contact binary was discovered on 24 April 1977, by American astronomer Charles Kowal at the Palomar Observatory in California, United States. It was named after Bacchus from Roman mythology.
1566 Icarus is a large near-Earth object of the Apollo group and the lowest numbered potentially hazardous asteroid. It has is 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.

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.

3192 A'Hearn, provisional designation 1982 BY1, is a carbonaceous asteroid from the inner regions of the asteroid belt, about 6 kilometers in diameter. It was discovered by American astronomer Edward Bowell at Lowell's Anderson Mesa Station in Flagstaff, Arizona, on 30 January 1982.
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.
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.
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.
3102 Krok, provisional designation 1981 QA, is a rare-type asteroid and slow rotator, classified as a near-Earth object of the Amor group, that measures approximately 1.5 kilometers in diameter.
161989 Cacus is a stony asteroid, classified as near-Earth object and a potentially hazardous asteroid of the Apollo group, approximately 1 kilometer in diameter. 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.
(457175) 2008 GO98, provisional designation 2008 GO98 with cometary number 362P, is a Jupiter family comet in a quasi-Hilda orbit within the outermost regions of the asteroid belt. It was discovered on 8 April 2008, by astronomers of the Spacewatch program at Kitt Peak National Observatory near Tucson, Arizona, in the United States. This presumably carbonaceous body has a diameter of approximately 15 kilometers (9 miles) and rotation period of 10.7 hours.
(85182) 1991 AQ, provisional designation 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.
