1990 QD1 is a small celestial object classified as a trans-Neptunian object, located in the outer region of our solar system. It was discovered on August 31, 1990, and is part of the Kuiper Belt, a region filled with icy bodies and remnants from the solar system's formation. This object has an estimated diameter of about 100 kilometers and orbits the Sun at a distance greater than that of Neptune. Its orbit is elliptical, and it takes several years to complete one revolution around the Sun, contributing to our understanding of the dynamics of the Kuiper Belt.
