AF Gem is an Algol-type eclipsing binary with a period of 1.2435 days. The period is found to have decreased slightly over the years that this object has been under observation. Approximately 800 observations in UBV have been analyzed by the Wood (1972) method, and orbital elements have been obtained. The primary eclipse is a transit, and the eclipses are partial. The spectral types of the components are estimated to be B9 V and G0 IV. AF Gem has a faint visual companion situated about 2 arcsec from the eclipsing pair. It is most probable that this star is a member of the system.
