221300

221300 is a numbered minor planet located in the main asteroid belt between Mars and Jupiter. Discovered on 28 February 2008 by the LINEAR survey at the Socorro observatory in New Mexico, the object received its provisional designation 2008 DX14 before its orbit was confirmed and it was assigned the permanent number 221300. The asteroid has not yet been given a formal name and is still referenced by its number.

Orbital calculations place 221300 in the inner part of the main belt, with a semi‑major axis of approximately 2.2 astronomical units. Its orbit is moderately eccentric, with an eccentricity of about 0.15, and the inclination relative to the ecliptic plane is roughly 5 degrees. The orbital period of the body is approximately 3.3 years, completing one circuit around the Sun in that time. Observational data indicate a rotation period of several hours, though its shape and composition remain largely uncharacterised.

Because of its position in the main belt and typical size for objects of its absolute magnitude (around 16.5), 221300 is estimated to be a few kilometers in diameter, likely composed of rocky silicate material common to S‑type asteroids. The asteroid has no known close encounters with Earth and is not classified as a potentially hazardous object. Further photometric and spectroscopic studies are required to determine its spectral type, albedo, and any possible binary system. As of the latest published records, no light‑curve data beyond the initial discovery measurements have been released.
