1887 Virton, provisional designation 1950 TD, is a stony asteroid from the outer region of the asteroid belt, about 22 kilometers in diameter. It was discovered by Belgian astronomer Sylvain Arend at Royal Observatory of Belgium in Uccle on 5 October 1950.[5]

The S-type asteroid is a member of the Eos family. It orbits the Sun at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,905 days). Its orbit shows an eccentricity of 0.11 and is inclined by 9.6 degrees to the ecliptic plane.[3] It has an albedo of about 0.11−0.14.[4][3]

The asteroid was named after the town and capital district, Virton, in the southern-most part Belgium. It is located very close to Robelmont, Arend's birthplace (also see 1145 Robelmonte).[2]
