1101 Clematis is a minor planet orbiting the Sun that was discovered by German astronomer Karl Wilhelm Reinmuth on September 22, 1928, in Heidelberg.[2] Initially it received the designation 1928 SJ. It was named for the clematis flower.
Photometric observations made in 2003 at the Santana Observatory in Rancho Cucamonga, California, give a synodic rotation period of 12.68 ± 0.01 hours. The light curve shows a brightness variation of 0.40 ± 0.05 in magnitude.[2]
This object is the namesake of a dynamic family of 5–16 asteroids that share similar spectral properties and orbital elements; hence they may have arisen from the same collisional event. All members have a relatively high orbital inclination.[3]
