Erato is a carbonaceous Themistian asteroid from the outer region of the asteroid belt, approximately 95 kilometers in diameter. Photometric measurements during 2004–2005 showed a rotation period of 9.2213±0.0007 h with an amplitude of 0.116±0.005 in magnitude. It is orbiting the Sun with a period of 5.52 yr, a semimajor axis of 3.122 AU, and eccentricity of 0.178. The orbital plane is inclined by an angle of 2.22° to the plane of the ecliptic.
Hecuba is a fairly large and bright main-belt asteroid. It was discovered by Karl Theodor Robert Luther on 2 April 1869, and named after Hecuba, wife of King Priam in the legends of the Trojan War in Greek Mythology. This object is orbiting the Sun with a period of 5.83 years and an eccentricity of 0.06. It became the first asteroid discovered to orbit near a 2:1 mean-motion resonance with the planet Jupiter, and is the namesake of the Hecuba group of asteroids.
Maria is a Main belt asteroid that was discovered by French astronomer Henri Joseph Perrotin on January 10, 1877. Its orbit was computed by Antonio Abetti, and the asteroid was named after his sister, Maria. This is the namesake of the Maria asteroid family; one of the first asteroid families to be identified by Japanese astronomer Kiyotsugu Hirayama in 1918.
Penelope is a large main belt asteroid that was discovered by Austrian astronomer Johann Palisa on August 7, 1879, in Pola. The asteroid is named after Penelope, the wife of Odysseus in Homer's The Odyssey. It is orbiting the Sun at a distance of 2.68 AU with an eccentricity (ovalness) of 0.18 and a period of 4.381 years. The orbital plane is tilted at an angle of 5.8° to the plane of the ecliptic.
Isabella is a large and dark asteroid from the central asteroid belt, approximately 80 kilometers in diameter. It was discovered in Pola by Johann Palisa on 12 November 1879. The origin of the name is unknown. The asteroid is probably composed of material similar to carbonaceous chondrites. It is classified as a member of the Nemesis family of asteroids.
Eos is a large main-belt asteroid that was discovered by Austrian astronomer Johann Palisa on January 18, 1882, in Vienna. In 1884, it was named after Eos, the Greek goddess of the dawn, to honour the opening of a new observatory that was hoped to bring about a new dawn for Viennese astronomy.
Eukrate is a rather large main-belt asteroid. It is dark and probably a primitive carbonaceous body. The asteroid was discovered by Robert Luther on March 14, 1885, in Düsseldorf. It was named after Eucrate, a Nereid in Greek mythology.
Oppavia is a sizeable Main belt asteroid. It was discovered by Austrian astronomer Johann Palisa on 31 March 1886 in Vienna and was named after Opava, a town in the Czech Republic, then part of Austria-Hungary, where Palisa was born. It is orbiting the Sun at a distance of 2.75 AU with an orbital eccentricity (ovalness) of 0.077 and a period of 4.55 yr. The orbital plane is inclined by an angle of 9.47° to the plane of the ecliptic.
Brigitta is a typical Main belt asteroid. It is a member of the Eos family.

This object is orbiting at a distance of 3.19 AU with a period of 5.70 years and an eccentricity (ovalness) of 0.15. The orbital plane is inclined at an angle of 5.61° to the plane of the ecliptic.
760 Massinga is a large background asteroid from the outer regions of the asteroid belt, approximately 70 kilometers in diameter. It was discovered by German astronomer Franz Kaiser at the Heidelberg Observatory on 28 August 1913. The stony S-type asteroid has a rotation period of 10.7 hours and is somewhat elongated in shape. It was named in memory of Adam Massinger (1888–1914), a German astronomer at Heidelberg who was killed in World War I.
