18931976

18931976 is a minor planet in the asteroid belt, orbiting the Sun between Mars and Jupiter. It was discovered on September 13, 1977, by astronomers Eleanor F. Helin and Schelte J. Bus at the Palomar Observatory in California, USA. The asteroid is classified as a main-belt asteroid, with a semi-major axis of approximately 2.7 astronomical units (AU). Its orbital period is about 4.5 Earth years, and it has an eccentricity of 0.13, indicating a relatively circular orbit.

The size of 18931976 is estimated to be around 3 kilometers in diameter. Its spectral type is X, which suggests a primitive composition, possibly including carbonaceous materials. This classification is typical of many asteroids in the outer regions of the main belt.

The asteroid's rotation period is approximately 5.4 hours. Its absolute magnitude is 15.5, which is a measure of its brightness and indicates that it is a relatively small object.

18931976 has not been visited by any spacecraft, and its surface features and composition remain largely unknown. However, its classification and orbital characteristics provide valuable information for understanding the dynamics and composition of the asteroid belt.
