Genua (minor planet designation: 485 Genua) is a minor planet orbiting the Sun.
Aethra is a metallic asteroid and Mars-crosser on an eccentric orbit from the asteroid belt. It measures approximately 40 kilometers in diameter.
Kallisto is a fairly typical, although sizeable Main belt asteroid. It is classified as an S-type asteroid. Like other asteroids of its type, it is light in colour. It was discovered by Johann Palisa on 8 October 1879, in Pola, and was named after the same nymph Callisto in Greek mythology as Jupiter's moon Callisto.
Vanadis is a fairly large main-belt asteroid with a diameter of around 100 km. It was discovered by A. Borrelly on August 27, 1884, in Marseilles and was named after Freyja (Vanadis), the Norse fertility goddess. The asteroid is orbiting the Sun at a distance of 2.67 AU with a period of 4.35 yr and an orbital eccentricity of 0.206. The orbital plane is inclined at an angle of 2.10° to the plane of the ecliptic.
Germania is a very large main-belt asteroid. It is classified as a B-type asteroid and is probably composed of dark, primitive carbonaceous material.
Arsinoë, minor planet designation 404 Arsinoë, is a large main-belt asteroid. It is classified as a C-type asteroid and is probably composed of carbonaceous material.
Vaticana is a large Main belt asteroid.
Edna is a large Main belt asteroid.
Emita is a minor planet orbiting the Sun that was discovered by the Italian astronomer Luigi Carnera on February 12, 1902. The meaning of the asteroid's proper name remains unknown.
Carina is a minor planet orbiting the Sun.
Evelyn is a main belt asteroid discovered by Raymond Smith Dugan on 19 January 1903. The asteroid was named after Evelyn Smith Dugan, mother of the discoverer.
Cava is a minor planet orbiting the Sun.
Peraga is a minor planet orbiting the Sun that was discovered by German astronomer Paul Götz on January 8, 1905, from Heidelberg.
Olympia is a minor planet orbiting the Sun.
Marianna is a minor planet orbiting the Sun.
Tekmessa is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on February 16, 1906. The name may have been inspired by the asteroid's provisional designation 1906 TK.
690 Wratislavia is a minor planet orbiting the Sun. Wratislavia was discovered on October 16, 1909. IRAS data shows it is about 135 km in diameter.
739 Mandeville is a minor planet located in the asteroid belt. Its absolute magnitude is 8.50. It was discovered on 7 February 1913 by Joel Hastings Metcalf in Winchester, Massachusetts, and assigned the provisional code 1913 QR. A later, duplicate discovery was assigned the code 1963 HE.
747 Winchester is an asteroid, a minor planet orbiting the Sun. It was discovered in 1913, and is named after the town in which it was discovered, Winchester, Massachusetts, in the USA.
769 Tatjana is a minor planet orbiting the Sun. The body was named such after Tatiana Larina, protagonist of Alexander Pushkin's poem "Eugene Onegin". It's possible that the name was suggested by the provisional designation of the asteroid, 1913 TA, but unlike bodies named by Wolf, Knopff and Metcalf in the years 1905–1909, there's no naming pattern to support this.
2021 LL37 is a large trans-Neptunian object in the scattered disc, around 600 kilometres (370 miles) in diameter. It was discovered on 12 June 2021, by American astronomers Scott Sheppard and Chad Trujillo using Cerro Tololo Inter-American Observatory's Dark Energy Camera in Chile, and announced on 31 May 2022. It was 73.9 astronomical units from the Sun when it was discovered, making it one of the most distant known Solar System objects from the Sun as of May 2022. It has been identified in precovery images from as far back as 28 April 2014.
