386 Siegena

Siegena (minor planet designation: 386 Siegena) is a very large main-belt asteroid. It is classified as a C-type asteroid and is probably composed of primitive carbonaceous material.

It was discovered by Max Wolf on March 1, 1894, in Heidelberg.

During 1999, the asteroid was observed occulting a star. The resulting chords provided a diameter estimate of 174 km.
