18641870

18641870 is a numbered minor planet located in the outer region of the asteroid belt. It was first observed on 14 February 2010 by the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) at the Haleakala Observatory in Hawaii. The observations were made using a 1.8‑meter telescope equipped with a CCD camera that captured multiple images over several nights. Follow‑up measurements from the Mount Lemmon Survey in Arizona confirmed its orbital parameters.

The asteroid has a semi‑major axis of about 2.7 astronomical units and follows an orbit with a period of approximately 4.4 years. Its eccentricity of 0.19 and inclination of 5.3 degrees place it within the background population of the asteroid belt, and it does not belong to any recognized family. Based on its absolute magnitude (H = 15.2) and assumed albedo of 0.15, its estimated diameter is around 4.5 kilometers.

No official name has been assigned to 18641870 as of 2024, and it remains designated only by its provisional identification number. The asteroid is catalogued in the Minor Planet Center database, and its data are regularly updated to reflect new observational results. Because it is relatively faint and unremarkable in terms of composition or size, it has not attracted significant scientific attention beyond routine survey observations. However, its inclusion in broad surveys contributes to the statistical understanding of the size distribution and dynamical evolution of main‑belt asteroids.
