10981989

10981989 is a minor planet in the asteroid belt, discovered on 1998 by the Lincoln Near-Earth Asteroid Research (LINEAR) project. It is part of the Flora family of asteroids, which are primarily composed of silicate minerals. The asteroid has a diameter of approximately 3.5 kilometers and orbits the Sun with a semi-major axis of about 2.2 astronomical units (AU). Its orbital period is roughly 3.3 years, and it has an eccentricity of 0.15, indicating a relatively circular orbit. The asteroid's rotation period is estimated to be around 5.5 hours. 10981989 is classified as a main-belt asteroid, and its spectral type is S, which suggests a stony composition. The asteroid's absolute magnitude is 14.1, which is a measure of its brightness. 10981989 is not considered a near-Earth object, as its orbit does not bring it close to Earth's orbit. The asteroid's name is derived from its provisional designation, which is a combination of the year of discovery and the order of discovery within that year.
