Schematic illustration of the internal structure of the Moon. Several lines of evidence imply that the lunar core is small, with a radius of about 350 km or less. [5] The diameter of the lunar core is only about 20% the diameter of the Moon itself, in contrast to about 50% as is the case for most other terrestrial bodies.
S-types are the most numerous kind of asteroid in the inner part of the asteroid belt. [23] OC meteorites are, likewise, the most common type of meteorite found on the Earth's surface. [23] The reflection spectra measured by remote observations of S-type asteroids, however, did not match that of OC meteorites.

The absolute magnitudes of most of the known asteroids are between 11 and 19, with the median at about 16. [67] On average the distance between the asteroids is about 965,600 km (600,000 miles), [68] [69] although this varies among asteroid families and

Dactyl (/ ˈ d æ k t ɪ l / DAK-til; formally (243) Ida I Dactyl) is a small asteroid moon 1,200 by 1,400 by 1,600 m (3,900 by 4,600 by 5,200 ft), in size) that orbits 243 Ida, a main-belt asteroid. It was imaged by the Galileo spacecraft on August 28, 1993; Dactyl was discovered while examining the delayed image downloads from Galileo on ...
The fossils were between 35.5 to 35.9 million years old and were found in a nearly 10-foot-long rock core: a tube-like sample taken from underneath the Gulf of Mexico by the scientific Deep Sea ...
The poles of astronomical bodies are determined based on their axis of rotation in relation to the celestial poles of the celestial sphere. Astronomical bodies include stars, planets, dwarf planets and small Solar System bodies such as comets and minor planets (e.g., asteroids), as well as natural satellites and minor-planet moons.
