243013

243013 is a minor planet in the outer region of the asteroid belt, orbiting the Sun between Mars and Jupiter. It was discovered on October 14, 1999, by the Lincoln Near-Earth Asteroid Research (LINEAR) project, an initiative to discover and track near-Earth objects. The asteroid is classified as a main-belt asteroid, with a semi-major axis of approximately 3.1 astronomical units (AU), indicating its position within the asteroid belt.

The orbital period of 243013 is roughly 5.5 Earth years, and its orbit has an eccentricity of about 0.15, which is relatively low, suggesting a nearly circular orbit. The asteroid's absolute magnitude, a measure of its brightness, is 15.5, which implies a diameter of around 2.5 kilometers. The surface composition of 243013 is not well-determined, but it is likely to be similar to other asteroids in the asteroid belt, composed primarily of rock and metal.

243013 does not pose any significant threat to Earth, as its orbit does not bring it close to our planet. It remains a subject of interest for astronomers studying the dynamics and composition of the asteroid belt. The discovery and ongoing study of minor planets like 243013 contribute to our understanding of the solar system's formation and evolution.
