Kaidun is a meteorite that fell on 3 December 1980 on a Soviet military base near what is now Al-Khuraybah in Hadhramaut, Yemen. A fireball was observed travelling from the northwest to the southeast, and a single stone weighing about 2 kilograms (4.4 lb) was recovered from a small impact pit. It has been suggested that Kaidun originated from the Martian moon of Phobos, but this is disputed.
