4179 Toutatis https://en.wikipedia.org/wiki/4179_Toutatis#Properties

Its rotation combines two separate periodic motions into a non-periodic result; to someone on the surface of Toutatis, the Sun would seem to rise and set in apparently random locations and at random times at the asteroid's horizon. It has a rotation period around its long axis (Pψ) of 5.38 days. This long axis is precessing with a period (Pφ) of 7.38 days.[13] The asteroid may have lost most of its original angular momentum and entered into this tumbling motion as a result of the YORP effect.[14]
