130146

130146 is a minor planet in the outer region of the asteroid belt, approximately 10 kilometers in diameter. It was discovered on 13 September 1999, by astronomers of the Lincoln Near-Earth Asteroid Research at the Lincoln Laboratory's ETS near Socorro, New Mexico. The Minor Planet Center, operated by the Smithsonian Astrophysical Observatory, has credited the discovery to the Lincoln Laboratory's ETS.

The semi-major axis of 130146's orbit is 3.16 astronomical units (AU), with an orbital period of 5.65 years. Its orbit has an eccentricity of 0.15 and an inclination of 10.4 degrees with respect to the ecliptic. The asteroid's observation arc begins with its official discovery observation at Lincoln Laboratory ETS.

Physical characteristics of 130146 are not well-determined. It has an absolute magnitude of 14.3, which corresponds to a diameter of approximately 10 kilometers, assuming an albedo of 0.15. The Collaborative Asteroid Lightcurve Link (CALL) does not list any rotational lightcurve data for this asteroid, indicating that its rotation period and shape are not yet known.

130146 is a non-family asteroid in the background population, meaning it does not belong to any known asteroid family. Its spectral type is not determined, but it is likely a common S-type asteroid, given its location in the asteroid belt. Further observations and analysis are needed to better understand the physical properties and orbital dynamics of this minor planet.
