14583

14583 is the numbered designation of a minor planet located in the Main Asteroid Belt between Mars and Jupiter. It was discovered on 12 April 1994 by astronomer Prof. T. S. Johnson at the Palomar Observatory in California. The asteroid received the provisional designation 1994 EA and was later assigned the permanent number 14583 when its orbit was confirmed.

The object orbits the Sun with a semi‑major axis of approximately 2.52 astronomical units, completing a full orbit every 4.00 Earth years. Its orbital eccentricity is 0.185, which gives it a perihelion distance of 2.05 AU and an aphelion distance of 3.00 AU. The inclination relative to the ecliptic plane is about 5.6°, placing it in a low‑inclination, relatively circular orbit typical of the inner main‑belt population.

Physical parameters derived from photometric observations suggest an absolute magnitude of 15.1, implying a diameter in the range of 3 to 5 kilometers, depending on the assumed albedo. No spacecraft fly‑by or detailed spectral analysis has been conducted to date, so its composition remains inferred from its taxonomic classification, which is likely S‑type based on its visible spectrum.

The asteroid does not yet have an official name; it is currently known solely by its numerical designation. Further observations are ongoing to refine its orbital elements and to search for a potential binary companion.
