9491

9491 is an asteroid classified within the main asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on November 19, 1981, by American astronomer Schelte J. Bus at Siding Spring Observatory in Australia. The asteroid is part of the asteroid classification known as S-type, which are characterized by their silicaceous (stony) composition made primarily of silicate minerals and nickel-iron metal.

The approximate diameter of 9491 is estimated to be around 5 to 10 kilometers, although precise measurements can vary due to observational challenges. Its orbital period around the Sun is roughly 3.3 years, with an orbit that takes it between 2.2 and 2.6 astronomical units (AU) from the Sun. The asteroid's orbit exhibits moderate eccentricity and inclination, typical of many inner-main belt objects.

9491 is of interest in planetary science due to its composition and orbital characteristics, which provide insights into the early solar system's formation and evolution. While it is not classified as a near-Earth object, understanding the properties of such main belt asteroids helps inform planetary defense strategies and asteroid mining prospects.

No significant information about spacecraft missions or exploration activities targeting 9491 has been recorded. Its observational data is primarily gathered through ground-based telescopes and contributes to ongoing research on asteroid diversity and dynamics within the main asteroid belt.

If further details are desired, updated measurements and studies are available through astronomical databases and publications specializing in asteroid research.
