129792

129792 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, 2005, by astronomers at the Palomar Observatory in California. The object is classified as a main-belt asteroid, with a semi-major axis of approximately 3.1 astronomical units (AU). Its orbital period is about 5.6 Earth years, and it has an eccentricity of 0.12, indicating a relatively circular orbit.

The asteroid has a diameter estimated to be around 5 kilometers, based on its absolute magnitude and assumed albedo. Its rotation period is not well-determined, but it is believed to be relatively slow, similar to other asteroids in its size range. The spectral classification of 129792 is not yet determined, but it is likely to be a C-type asteroid, which are common in the outer asteroid belt and are characterized by their dark, carbonaceous surfaces.

The asteroid's name, "129792," is its provisional designation in the Minor Planet Center's database. It has not yet been named by the International Astronomical Union, which is responsible for naming asteroids and other small Solar System bodies. The naming process typically involves suggestions from the discoverers or other interested parties, followed by a formal approval process.

129792 is one of millions of known asteroids in the Solar System, and its study contributes to our understanding of the formation and evolution of the asteroid belt. As more observations are made and data is collected, the properties of 129792 and other asteroids will become better understood, providing insights into the early history of the Solar System.
