240 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.

[1] Photometric observations of the asteroid made during 2022 were used to produce a light curve that showed a rotation period of 10.565±0.002 h with a brightness variation of 0.07±0.01 in magnitude.

[3] It is very dark and is classified as a C-type asteroid, probably composed of primitive carbonaceous material.
