'''1167 Dubiago''' is an outer [[main belt asteroid]] orbiting the [[Sun]]. Approximately 63 kilometers in diameter, it makes a revolution around the Sun once every 6 years. It completes one rotation once every 14 hours. It was discovered by [[Evgenii Fedorovich Skvortsov]] on August 3, 1930. Its provisional designation was 1930 PB.<ref name="a"/>

1167 Dubiago, provisional designation 1930 PB, is a larger asteroid from the outer region of the asteroid belt, approximately 63 kilometers in diameter. It was discovered by Soviet astronomer Evgenii Skvortsov at the Crimean Simeiz Observatory on 3 August 1930.[8]

It orbits the Sun at a distance of 3.2–3.7 AU once every 6 years and 4 months (2,304 days). It has a rotation period of 14.3 hours and a low geometric albedo of 0.036 and 0.051, as measured by the two infrared satellites, Akari and IRAS, respectively.[4][5]

Dubiago belongs to the group of D-type minor planets, of which a total 46 bodies are known, many of them Jupiter trojans or centaurs, with the largest being 10199 Chariklo and 624 Hektor.[9] It is thought that the Martian moon Phobos has a similar composition, and that the Tagish Lake meteorite origins from a D-type asteroid.

The asteroid was named in honor of Alexander Dubyago (1903–1959), an eminent astronomer of the Soviet Union. The lunar crater Dubyago is also named in his and his father's honour.[2]
