2007 EB26 is one of the closest orbiting objects to the Sun. It has the second-smallest semi-major axis (0.55 AU) of any known object orbiting the Sun, after Mercury. It is classified as an Apohele asteroid and does not cross Earth's orbit. It approaches within 0.116 astronomical unit|AU (17,400,000 km; 10,800,000 mi) of the Sun approximately every 148 days, before leaving for a distance of 0.979 AU. Only thirteen known asteroids have perihelia smaller than 2007 EB26.[4]
