Phobos is a small irregularly shaped object with a mean. The known densities of TNOs in this size range are remarkably low 112 gcm 3 implying that the objects retain significant internal. Lowell proposed the Planet X hypothesis to explain apparent discrepancies in the orbits of the giant planets.
Perhaps inspired by Johannes Kepler and quoting Keplers third law Swifts satire Gullivers Travels refers to two moons in Part 3 Chapter 3 the Voyage to Laputa in which the astronomers of Laputa are described as having discovered two satellites of Mars orbiting at distances of 3 and 5 Martian diameters and periods of 10 and 215.

The four Galileans are all over 3100 kilometres 1900 mi in diameter. Earths only natural satellite is simply called the Moon because people didnt know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610. Their orbits are unstable and will fall into other resonances or be kicked into other orbits over thousands of years.
Since Neptune was named for the Roman god of the sea its moons are named for various lesser sea gods and nymphs in Greek mythology. When people write just the moon they are usually talking about the moon of the Earth. The inner part of the ring formed a large moon.

All imaged icy moons with radii greater than 200 km except Proteus are clearly round although those under 400 km that have had their shapes carefully measured are not in hydrostatic equilibrium.
That means it spins nearly perfectly upright and so does not experience seasons as many other planets do. The search began in the mid-19th century and continued at the start of the 20th with Percival Lowells quest for Planet X. Although no other moons of Earth have been found to date there are various types of near-Earth objects in 11 resonance with it they orbit at a similar distance as Earth the Sun rather than the planet itself.
In astronomy a trojan is a small celestial body mostly asteroids that shares the orbit of a larger body remaining in a stable orbit approximately 60 ahead of or behind the main body near one of its Lagrangian points L 4 and L 5Trojans can share the orbits of planets or of large moons. Some other planets have many moons and some have none. Jupiter for instance has 79 known moons.
