51135 is a minor planet in the asteroid belt, orbiting the Sun between Mars and Jupiter. It was discovered on October 11, 1999, by the Lowell Observatory Near-Earth-Object Search (LONEOS) at Anderson Mesa Station in Flagstaff, Arizona. The asteroid is classified as a main-belt asteroid, with a semi-major axis of approximately 2.67 astronomical units (AU). Its orbital period is about 4.27 years, and it has an eccentricity of 0.155. The absolute magnitude of 51135 is 15.7, indicating a relatively small size. The asteroid's rotation period is estimated to be around 5.5 hours. As of now, no moons have been discovered orbiting 51135. The asteroid's spectral type is not yet determined, but it is likely to be a common type found in the asteroid belt, such as C-type or S-type. Further observations and studies are needed to better understand the physical properties and composition of 51135.
