205328

205328 is an asteroid in the outer region of the asteroid belt, between the orbits of Mars and Jupiter. It was discovered on September 12, 2009, by astronomers with the Mount Lemmon Survey at the Discovery Channel's Tautenburg Observatory in Germany. The asteroid is classified as a main-belt asteroid, which means it orbits the Sun in the same region as the majority of known asteroids.

The asteroid has an estimated diameter of about 0.5 kilometers. It orbits the Sun with a period of approximately 3.6 years, completing one orbit for every 1,316 Earth days. The asteroid's orbit has an eccentricity of about 0.15, which means it is slightly elongated and deviates from a perfect circle.

205328 has an absolute magnitude of about 15.5, which indicates its overall brightness. The asteroid's surface composition and rotation period are not well-documented, as detailed observations are limited. However, it is classified as a stony S-type asteroid, which suggests it is primarily composed of silicate minerals.

The asteroid's designation, 205328, is a temporary one assigned by the Minor Planet Center. It will be given a permanent name and number once it is officially designated by the International Astronomical Union. The asteroid's provisional designation, 2009 SP317, reflects the year of its discovery and the half-month period and sequence number within that period.

205328 is one of the many thousands of asteroids in the asteroid belt that have been discovered since the beginning of systematic asteroid surveys in the 19th century. These surveys have provided valuable data on the composition, distribution, and dynamics of asteroids, contributing to our understanding of the early solar system and the potential origins of life on Earth.
