10145

10145 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on February 28, 1994, by astronomers Eleanor F. Helin and Kenneth J. Lawrence at the Palomar Observatory in California, USA. The asteroid is classified as a main-belt asteroid, which means it orbits the Sun within the asteroid belt.

10145 has an estimated diameter of about 12 kilometers (7.5 miles) and a rotation period of approximately 6.2 hours. Its orbit is nearly circular, with an eccentricity of 0.05, and it completes one orbit around the Sun every 3.8 Earth years. The asteroid's spectral type is S, indicating that it has a stony composition.

The asteroid is named after the American astronomer Carl Sagan, who was known for his contributions to the fields of astronomy, astrobiology, and science communication. The naming citation was published by the Minor Planet Center on April 2, 1999 (M.P.C. 34051).

As of now, there are no known moons or companions orbiting 10145. The asteroid has not been visited by any spacecraft, and its surface features remain unknown. However, future missions to the asteroid belt may provide more information about this minor planet and its properties.
