743 Eugenisis is a minor planet orbiting the Sun that was discovered by German astronomer Franz Kaiser in 1913.
Photometric observations of this asteroid collected during 2004 show a rotation period of 10.23 ± 0.01 hours with a brightness variation of 0.20 ± 0.02 magnitude.[3] The spectrum of this object matches the Ch class in the SMASS taxonomy, indicating a carbonaceous surface with a hydrous component.[4]
