319998 is a minor planet in the outer region of the asteroid belt, orbiting the Sun between Mars and Jupiter. It was discovered on March 21, 2010, by astronomers at the Mount Lemmon Survey, an astronomical survey conducted by the University of Arizona. The object is classified as a main-belt asteroid, with a semi-major axis of approximately 3.1 astronomical units (AU), a perihelion distance of 2.7 AU, and an aphelion distance of 3.5 AU. Its orbital period around the Sun is about 5.5 Earth years. The asteroid has an estimated diameter of around 1.5 kilometers, based on its absolute magnitude of 16.5. The rotational period of 319998 is not yet determined, and its spectral classification is also unknown. The asteroid's orbit is not particularly eccentric or inclined, typical for main-belt asteroids. As of now, no moons or other companions have been discovered orbiting 319998. The asteroid's designation, 319998, is a number assigned by the Minor Planet Center, which is responsible for the identification and cataloging of minor planets.
