25899

25899 is a minor planet in the outer region of the asteroid belt, approximately 12 kilometers in diameter. It was discovered on 14 September 1992, by astronomers Carolyn S. Shoemaker and Eugene M. Shoemaker at the Palomar Observatory in California, United States. The asteroid is named after the year of its discovery, 25899.

The orbital period of 25899 is approximately 4.45 years, and its semi-major axis is about 2.7 astronomical units (AU). Its orbit has an eccentricity of 0.11 and an inclination of 1.9 degrees with respect to the ecliptic. The asteroid's spectral type is X, indicating that its surface composition is unknown.

25899 has a rotation period of about 6.2 hours. Its absolute magnitude is 14.5, which corresponds to a diameter of approximately 12 kilometers, assuming an albedo of 0.20. The asteroid's light curve amplitude is 0.15 magnitude, indicating a relatively spherical shape.

25899 is part of the Flora family of asteroids, which are thought to have originated from a single parent body that was disrupted by a collision. The Flora family is located in the inner region of the asteroid belt and is characterized by its high albedo and spectral type.

In summary, 25899 is a minor planet in the outer region of the asteroid belt, with an orbital period of approximately 4.45 years and a diameter of about 12 kilometers. It is part of the Flora family of asteroids and has a spectral type of X, indicating that its surface composition is unknown.
