(25140) Schmedemann is an asteroid in the main asteroid belt between the planets Mars and Jupiter . It was named after Nico Schmedemann from the Free University of Berlin . The small body was discovered at Anderson Mesa Station on September 22, 1998 as part of NASA's Lowell Observatory Near-Earth Object Search program. The program is used to record potentially dangerous small bodies in the vicinity of the earth.
The asteroid orbits the sun in 3.83 years at an average distance of 2.44 AU with an eccentricity of ~ 0.2 and an inclination of ~ 5.4 ° in relation to the plane of the earth's orbit. With an assumed geometric albedo of 12%, an average diameter of approx. 4 km can be estimated from its absolute brightness of 15 mag . The closest distance between the asteroid and Earth in their orbits around the Sun is about 0.9 AU or 134.6 million km. The asteroid therefore does not pose a threat to an impact on Earth.
The asteroid was named after Nico Schmedemann from the Free University of Berlin on July 12, 2014 .
