39624

39624 is a minor planet located in the asteroid belt between the orbits of Mars and Jupiter. It was discovered on January 12, 1965, by the Dutch astronomer Cornelis Johannes van Houten, his wife Ingrid van Houten-Groeneveld, and Tom Gehrels during the Palomar–Leiden Trojan Survey. The asteroid was later named after the Dutch astronomer and mathematician Adriaan van Maanen, though its official designation remains 39624.

39624 belongs to the main belt asteroids, which are rocky remnants from the early solar system. Its orbit has a semi-major axis of approximately 2.8 astronomical units (AU) from the Sun, with an orbital period of around 4.7 years. The asteroid has a relatively circular orbit with a low inclination to the ecliptic plane, indicating a stable trajectory.

Little is known about its physical properties, but estimates suggest it has a diameter of roughly 3 to 5 kilometers. Like many asteroids, 39624 is likely composed of silicate materials, though its exact composition remains unconfirmed without further observation. It does not appear to have any known satellites or unusual features that distinguish it from other main-belt asteroids.

39624 has not been the subject of extensive scientific study, and its naming reflects its association with the broader field of astronomical research rather than any distinctive characteristics. It remains one of the many thousands of minor planets cataloged in the solar system, contributing to our understanding of the early formation and evolution of the inner solar system.
