43898

43898 is a minor planet in the outer region of the asteroid belt, orbiting the Sun between Mars and Jupiter. It was discovered on October 13, 1999, by astronomers at the Lowell Observatory Near-Earth-Object Search (LONEOS) program. The asteroid is classified as a main-belt asteroid, with a semi-major axis of approximately 3.07 astronomical units (AU). Its orbital period is about 5.53 years, and it has an eccentricity of 0.13, indicating a relatively circular orbit.

The size of 43898 is estimated to be around 4.5 kilometers in diameter, based on its absolute magnitude of 14.5. Its spectral type is classified as X, which is a generic classification for asteroids with unknown or featureless spectra. This classification suggests that the asteroid's surface composition is not well understood.

43898 does not have any known moons or companions. Its rotation period is not yet determined, and its shape and surface features are also unknown. The asteroid's orbit does not bring it close to Earth, and it is not considered a potentially hazardous object.

The designation "43898" refers to the asteroid's sequential number in the Minor Planet Center's catalog. The asteroid has not been named, and the discovery was made by an automated survey, so there is no specific person or location associated with its name.
