742 Edisona is a minor planet, specifically an asteroid orbiting in the asteroid belt that was discovered by German astronomer Franz Kaiser on February 23, 1913. It was named for inventor Thomas Edison.2 This asteroid is orbiting 3.01 AU with a period of 5.22 years and an eccentricity of 0.119. The orbital plane is inclined at an angle of 11.2° to the plane of the ecliptic.1 This is a member of the dynamic Eos family of asteroids that most likely formed as the result of a collisional breakup of a parent body.3
Photometric observations made during 2008 were used to produce a light curve of 742 Edisona showing a rotation period of 18.52±0.01 with a brightness variation of 0.30±0.01 in magnitude.4 It spans a girth of approximately 45.6 km.1
