705 Erminia is a minor planet orbiting the Sun. Its name derives from the comic opera Erminie . An occultation on 8 December 2014 gave 3 chords, with one measurement suggesting a small moon 6-10 kilometers wide at a distance of 400 kilometers to the primary. [3]
Io is carbonaceous asteroid in the central region of the asteroid belt, approximately 170 kilometers in diameter. It is an identified Eunomian interloper.
Hera is a moderately large main-belt asteroid with an orbital period of 4.44 years. It was discovered by Canadian-American astronomer James Craig Watson on September 7, 1868, and named after Hera, queen and fifth in power of the Olympian gods in Greek mythology. This is a stony S-type asteroid with a silicate surface composition.

It was discovered on 7 September 1896, by astronomer Max Wolf at Heidelberg Observatory in Germany. The asteroid was named for the House of Zähringen, a medieval noble family that ruled parts of Swabia and Switzerland.
Happelia is a minor planet orbiting the Sun. On 24 February 2017 a possible small 3-kilometer moon was found orbiting the asteroid, based on occultation observations.
Octavia is a minor planet orbiting the Sun. At 15:45 UTC on October 6, 2014, the 13.5 magnitude asteroid occulted with magnitude 8.1 TYC 1299-00020-1, and was visible in Taiwan.
618 Elfriede is a minor planet orbiting the Sun. On July 24, 2013, it occulted the magnitude 12.8 star 2UCAC 23949304, over parts of Mexico and southwestern United States.
693 Zerbinetta is a minor planet orbiting the Sun. It was discovered on 21 September 1909 by August Kopff in Heidelberg. It was named after a character in Richard Strauss' opera Ariadne auf Naxos.
976 Benjamina is a dark background asteroid from the outer regions of the asteroid belt, approximately 81 kilometers in diameter. It was discovered on 27 March 1922, by Russian-French astronomer Benjamin Jekhowsky at the Algiers Observatory in North Africa. The large X/D-type asteroid has a rotation period of 9.7 hours and is likely regular in shape. It was named after the discoverer's son.
1143 Odysseus, provisional designation 1930 BH, is a large Jupiter trojan located in the Greek camp of Jupiter's orbit. It was discovered on 28 January 1930, by German astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany, and later named after Odysseus, the legendary hero from Greek mythology. The dark D-type asteroid has a rotation period of 10.1 hours. With a diameter of approximately 125 kilometers, it is among the 10 largest Jovian trojans.
2244 Tesla, provisional designation 1952 UW1, is a carbonaceous asteroid from the central region of the asteroid belt, approximately 25 kilometers in diameter. It was discovered on 22 October 1952, by Serbian astronomer Milorad Protić at the Belgrade Observatory, then Federal People's Republic of Yugoslavia, now Serbia. It is named after the inventor Nikola Tesla.
1918 Aiguillon provisional designation 1968 UA, is a dark asteroid from the outer region of the asteroid belt, approximately 20 kilometers in diameter.

It was discovered on 15 August 1939, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany. The asteroid was named after composer Johannes Brahms.
8306 Shoko, provisional designation 1995 DY1, is a Florian asteroid and a synchronous binary system from the inner regions of the asteroid belt, approximately 3 kilometers (2 miles) in diameter. It was discovered on 24 February 1995, by Japanese astronomer Akimasa Nakamura at the Kuma Kogen Astronomical Observatory in southern Japan, who named it after Japanese singer-songwriter Shoko Sawada. The likely S-type asteroid has a rotation period of 3.35 hours. The discovery of its 1.3-kilometer minor-planet moon was announced in December 2013.
4672 Takuboku, provisional designation 1988 HB, is a background asteroid from the outer regions of the asteroid belt, approximately 35 kilometers in diameter. It was discovered on 17 April 1988, by Japanese astronomers Seiji Ueda and Hiroshi Kaneda at the Kushiro Observatory on Hokkaido, Japan. The asteroid was named after the Japanese poet Takuboku Ishikawa. In 2005, measurement of the body's occultation ellipse also gave 35.0 × 35.0 kilometers.
5176 Yoichi, provisional designation 1989 AU, is a background asteroid from the central regions of the asteroid belt, approximately 17 kilometers in diameter. It was discovered on 4 January 1989, by Japanese astronomers Seiji Ueda and Hiroshi Kaneda at the Kushiro Observatory on Hokkaido, Japan. The likely elongated asteroid has a brightness variation of 0.45 magnitude, and occulted a star in the constellation Cetus in November 2014. It was named for the Japanese town of Yoichi.
4388 Jürgenstock, provisional designation 1964 VE, is a bright Phocaea asteroid from the inner regions of the asteroid belt, approximately 4.7 kilometers in diameter.
