742 Edisona is a minor planet orbiting the Sun that was discovered by German astronomer Franz Kaiser on February 23, 1913. It was named for inventor Thomas Edison. This asteroid is orbiting with a period of and an eccentricity of 0.119. The orbital plane is inclined at an angle of 11.2° to the plane of the ecliptic. 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. Photometric observations made during 2008 were used to produce a light curve of 742 Edisona showing a rotation period of with a brightness variation of in magnitude. It spans a girth of approximately 45.6 km. References External links Eos asteroids Edisona Edisona S-type asteroids (Tholen) K-type asteroids (SMASS) 19130223
