1790 Volkov, provisional designation 1967 ER, is a stony asteroid from the inner regions of the asteroid belt, about 9 kilometers in diameter. It was discovered on 9 March 1967 by Russian astronomer Lyudmila Chernykh at Crimean Astrophysical Observatory (CrAO) in Nauchnyj.[8]
The S-type asteroid belongs to the large Flora family of inner belt asteroids. It orbits the Sun at a distance of 2.0–2.5 AU once every 3 years and 4 months (1,223 days). Its orbit shows an eccentricity of 0.10 and an orbital inclination of 5 degrees towards to the plane of the ecliptic. It has a rotation period of 10.742 hours and an albedo of about 0.25, determined by the Japanese Akari and the WISE/NEOWISE space-missions.[4][5]
The minor planet was named in honor of Russian–Soviet cosmonaut Vladislav Nikolayevich Volkov, flight engineer of the Soyuz 11 spacecraft, who died at the age of 35 during the vehicle's return to Earth after completing the flight program of the Salyut station on 30 June 1971. The lunar crater Volkov is also named after him. The minor planets 1789 Dobrovolsky and 1791 Patsayev were named in honour of his dead crew members.[2] The names of all three cosmonauts are also engraved on the plaque next to the sculpture of the Fallen Astronaut on the Moon, which was placed there during the Apollo 15 mission, containing the names of eight American astronauts and six Soviet cosmonauts, who had all died in service.
