HD 93963 is a binary star in the constellation Leo Minor. At an apparent magnitude of +9.18, it is not visible to the naked eye. Parallax measurements give a distance of 268 light-years (82.3 parsecs) and 273 light-years (83.8 parsecs) for the primary and secondary component, respectively. Interstellar extinction causes the system's magnitude to be reduced by 0.10±0.05 magnitudes.
