There are at least 19 natural satellites in the Solar System that are known to be massive enough to be close to hydrostatic equilibrium: seven of Saturn, five of Uranus, four of Jupiter, and one each of Earth, Neptune, and Pluto. Alan Stern calls these satellite planets, although the term major moon is more common.
S/2023 U 1 is the smallest and faintest natural satellite of Uranus known, with a diameter of around 8–12 km (5–7 mi). It was discovered on 4 November 2023 by Scott S. Sheppard using the 6.5-meter Magellan–Baade Telescope at Las Campanas Observatory, Chile, and later announced on 23 February 2024. [1]
The catalog's first object is 1 Ceres, discovered by Giuseppe Piazzi in 1801, while its best-known entry is Pluto, listed as 134340 Pluto. The vast majority (97.3%) of minor planets are asteroids from the asteroid belt (the catalog uses a color code to indicate a body's dynamical classification).
In astronomy, a resonant trans-Neptunian object is a trans-Neptunian object (TNO) in mean-motion orbital resonance with Neptune.The orbital periods of the resonant objects are in a simple integer relations with the period of Neptune, e.g. 1:2, 2:3, etc. Resonant TNOs can be either part of the main Kuiper belt population, or the more distant scattered disc population.
