10191

10191 is a minor planet located in the asteroid belt between the orbits of Mars and Jupiter. It was discovered on October 16, 1990, by astronomers at the Palomar Observatory in California, United States. The object was officially designated as 10191 and later named **1990 UO3** during its initial observation period.

The asteroid belongs to the main belt population, which consists of rocky remnants from the early solar system. Its orbit has a semi-major axis of approximately 2.6 astronomical units (AU), meaning it is roughly 2.6 times the average distance between Earth and the Sun. The eccentricity of its orbit is low, indicating a nearly circular path, while its inclination relative to Earth's orbital plane is about 10 degrees.

10191 has not been extensively studied, and its physical characteristics, such as size, shape, and composition, remain largely unknown. Most asteroids of this size are estimated to be several kilometers in diameter, though precise measurements require further observation. It does not appear to have any known moons or unusual features that distinguish it from other main-belt asteroids.

While 10191 is not classified as a near-Earth object, its orbit has been monitored as part of broader asteroid tracking efforts to understand the dynamics of the solar system. It is not considered a threat to Earth based on current orbital data.

Researchers continue to study asteroids like 10191 to gain insights into the formation and evolution of the solar system. Observations from telescopes and space missions, such as NASA’s NEOWISE mission, contribute to expanding knowledge about these distant objects.
