203733

203733 is a minor planet in the asteroid belt, located between the orbits of Mars and Jupiter. It was discovered on October 24, 2003, by astronomers at the Palomar Observatory in California. The asteroid is classified as a main-belt asteroid, which means it orbits the Sun in the region of space between Mars and Jupiter.

The asteroid has an estimated diameter of about 2.5 kilometers. Its orbit has a semi-major axis of approximately 2.7 astronomical units (AU), with an orbital period of about 4.4 Earth years. The orbital eccentricity is 0.12, and the inclination of its orbit to the ecliptic plane is about 10 degrees.

203733 has a relatively slow rotation period of about 12.5 hours. Its spectral type is classified as X, which indicates that it has a primitive composition, likely consisting of carbonaceous material. This suggests that the asteroid may contain organic compounds and water, making it of interest to scientists studying the early solar system and the origins of life.

The asteroid's name has not yet been officially assigned by the International Astronomical Union. As of now, it is known by its provisional designation, 203733. Further observations and studies are needed to better understand its physical properties and composition.
