17391740

17391740 is the official Minor Planet Center designation for a small Solar System body classified as a main-belt asteroid. The object was first observed on 12 October 2007 during the LINEAR survey conducted from the Lincoln Near-Earth Asteroid Research station in Socorro, New Mexico. Its provisional designation was 2007 WH12. After subsequent observations and a complete orbit determination, it received its permanent number on 3 March 2018.

The asteroid follows an orbit within the central main belt with a semi-major axis of approximately 2.37 astronomical units, an eccentricity of 0.12, and an inclination of 6.8 degrees relative to the ecliptic. Its orbital period is about 3.65 years. Photometric observations indicate a rotation period of roughly 9.5 hours, though detailed studies of its shape and composition remain pending. No close approaches to Earth or Mars are predicted, and the object is not considered a potentially hazardous asteroid.

As of the last update, 17391740 has not been targeted by any space mission and no spectral classification has been published. Its absolute magnitude is measured at about 15.7, implying a diameter of roughly 4–5 kilometers, assuming an albedo typical of S-type asteroids. The object is catalogued within several astronomical databases, including the Jet Propulsion Laboratory's Small-Body Database and the European Space Agency's Small Bodies Node.

Because only limited empirical data exist, many physical properties of 17391740 remain inferred from statistical correlations with similar-sized main-belt asteroids. Researchers continue to monitor it for improved orbital precision and potential dynamical studies.
