114 Kassandra is a large and dark main-belt asteroid. It belongs to the rare class T. It was discovered by C. H. F. Peters on July 23, 1871, and is named after Cassandra, the prophetess in the tales of the Trojan War.

This object is classified as a rare T-type asteroid, with parts of the spectrum displaying properties similar to the mineral troilite and to carbonaceous chondrite.<ref name="Dotto2002"/> The shape of the spectrum also appears similar to fine grain from the Ornans meteorite, which landed in France in 1868.<ref name="Hamilton2010"/> The light curve for this asteroid displays a period of 10.758 ± 0.004 hours with a brightness variation of 0.25 ± 0.01 in magnitude.<ref name="Hutton1988"/>

In 2001, 114 Kassandra was observed by radar from the Arecibo Observatory. The return signal matched an effective diameter of 100 ± 14 km. This is consistent with the asteroid dimensions computed through other means.<ref name="icarus186_1_126"/>

In popular media

The 2009 miniseries Meteor featured 114 Kassandra being sent on a collision course with Earth due to a comet impact and the effort by scientists to stop it.
