Asteroids of this family move in a 4: 9 orbital resonance with the planet Mars around the sun . The group is also called the Ariadne family, after the asteroid (43) Ariadne .

(7268) Chigorin was named on March 9, 2001 after the Russian chess player Michail Tschigorin (1850-1908, English transcription from Russian: Mikhail Chigorin ), who was one of the leading chess masters of his era and who contributed significantly to the spread of chess in Russia .
