29958

29958 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on October 2, 1999, by the Lincoln Near-Earth Asteroid Research (LINEAR) project, a collaborative effort between the United States Air Force, NASA, and MIT. The asteroid is classified as a main-belt asteroid, with a semi-major axis of approximately 2.6 astronomical units (AU) and an orbital period of about 4.1 years. Its diameter is estimated to be around 4.5 kilometers, based on its absolute magnitude of 14.5. The asteroid has a relatively low eccentricity of 0.11, indicating a nearly circular orbit. 29958 completes one rotation on its axis approximately every 5.2 hours. The asteroid's spectral type is not well-determined, but it is likely to be of the S-type, which is common among main-belt asteroids. This classification suggests that the asteroid's surface is composed of silicate materials, similar to those found on Earth. As of now, no moons have been discovered orbiting 29958. The asteroid's orbit does not bring it close to Earth, and it is not considered a potentially hazardous object.
