165667

165667 is a minor planet in the asteroid belt, orbiting the Sun between Mars and Jupiter. It was discovered on February 24, 2003, by astronomers at the Palomar Observatory in California, United States. The asteroid is part of the Flora family, a group of asteroids that share similar orbital characteristics and are believed to have originated from a single parent body that was disrupted by a collision.

The asteroid has an estimated diameter of approximately 2.5 kilometers. Its orbit is relatively stable, with an orbital period of about 3.6 Earth years. The semi-major axis of its orbit is 2.6 astronomical units (AU), and its eccentricity is 0.12. The inclination of its orbit to the ecliptic plane is about 5.5 degrees.

165667 has not been visited by any spacecraft, and little is known about its physical properties. Its spectral classification is S-type, indicating that it is likely composed of silicate materials, similar to the composition of the Earth's crust. The asteroid's rotation period is estimated to be around 5.5 hours.

The designation "165667" is a numerical identifier assigned by the Minor Planet Center, the internationally recognized authority for naming and cataloging minor planets. The asteroid does not have an official name, although it has been informally referred to as "2003 DW12" in some astronomical literature.
