20756

20756 is an asteroid located in the main asteroid belt between Mars and Jupiter. It was discovered on October 16, 1992, by astronomers Carolyn S. Shoemaker and David H. Levy at the Palomar Observatory in California, United States. The asteroid is classified as a stony S-type asteroid, which means it has a composition similar to ordinary chondrites, a type of meteorite.

20756 has an estimated diameter of about 3.5 kilometers. Its orbit is relatively stable, with a semi-major axis of approximately 2.4 astronomical units (AU) and an orbital period of about 3.6 Earth years. The asteroid's orbit has an eccentricity of 0.13 and an inclination of 1.9 degrees relative to the ecliptic plane.

The asteroid's rotation period is approximately 5.2 hours. It has a relatively low albedo, indicating a dark surface. The asteroid's spectral characteristics suggest it may have a surface composed of silicate minerals, which is typical for S-type asteroids.

20756 has not been visited by any spacecraft as of 2023. Its orbit and physical characteristics make it a subject of interest for future studies, particularly in the context of understanding the composition and dynamics of the main asteroid belt.
