D. Pray, Carbuncle Hill Observatory, Greene, RI, U.S.A.; P. Pravec, P. Kusnirak, and K. Hornoch, Ondrejov Observatory; M. Husarik, M. Pikler, and G. Cervak, Skalnate Pleso Observatory; S. Gajdos, Modra Observatory; and F. Colas and J. Lecacheux, IMCCE and Pic du Midi Observatory, report that photometric observations obtained during 2007 Dec. 7 to 2008 Jan. 17 reveal that minor planet (7225) is a binary system with an orbital period of 14.67 +/- 0.01 hr. The primary shows a period of 2.4400 +/- 0.0001 hr, and it has a lightcurve amplitude of 0.11 mag, suggesting a nearly spheroidal shape. Mutual eclipse/occultation events indicate a secondary-to-primary mean-diameter ratio of 0.21 +/- 0.02.
