In the main asteroid belt, there appear to be two primary populations of asteroid: a dark, volatile-rich population, consisting of the C-type and P-type asteroids, with albedos less than 0.10 and densities under 2.2 g/cm 3, and a dense, volatile-poor population, consisting of the S-type and M-type asteroids, with albedos over 0.15 and densities ...
2023 FW 13 is an asteroid that was spotted on March 28, 2023, from the Pan-STARRS telescope at Hawaii, United States. It circles the sun in sync with Earth in such a way that it appears to orbit Earth, but well outside Earth's Hill sphere, making it a quasi-satellite.
