1394 Algoa, provisional designation 1936 LK, is a stony asteroid from the inner regions of the asteroid belt, about 14 kilometers in diameter. It was discovered on 12 June 1936, by English-born South-African astronomer Cyril Jackson at Union Observatory in Johannesburg, South Africa.[6]
The S-type asteroid orbits the Sun at a distance of 2.3–2.6 AU once every 3 years and 10 months (1,392 days). Its orbit shows an eccentricity of 0.08 and is tilted by 3 degrees to the plane of the ecliptic. It has a rotation period of 2.768 hours[4][5] and an assumed albedo of 0.20.[3]
The minor planet is named after the historical Algoa Bay, about 700 kilometers east of the Cape of Good Hope, South Africa.[2]
