20615

20615 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on February 1, 1999, by the Lincoln Near-Earth Asteroid Research (LINEAR) project, a collaborative effort between the United States Air Force, NASA, and the Massachusetts Institute of Technology. The asteroid is approximately 2.5 kilometers in diameter and has an orbital period of about 4.3 years. Its orbit is inclined at an angle of 11.5 degrees to the ecliptic plane, and it has an eccentricity of 0.15, indicating a relatively circular orbit.

The designation 20615 is a temporary designation given by the Minor Planet Center, which is responsible for the designation and cataloging of minor planets. The asteroid has not yet been named, and the process of naming it involves a proposal from the discoverer or a collaborating astronomer, followed by a review and approval by the International Astronomical Union's Working Group for Small Bodies Nomenclature.

20615 is classified as a main-belt asteroid, meaning it orbits within the asteroid belt and is not a near-Earth object. Its spectral type is unknown, but it is likely a C-type asteroid, which are common in the outer regions of the asteroid belt and are characterized by their dark, carbonaceous surfaces. The asteroid's rotation period is also unknown, but it is likely to be several hours, based on the typical rotation periods of main-belt asteroids.

In summary, 20615 is a minor planet in the asteroid belt, discovered in 1999 by the LINEAR project. It is approximately 2.5 kilometers in diameter, has an orbital period of about 4.3 years, and is likely a C-type asteroid. The asteroid has not yet been named, and its spectral type and rotation period are unknown.
