The adjectival forms of the names of astronomical bodies are not always easily predictable. Attested adjectival forms of the larger bodies are listed below, along with the two small Martian moons; in some cases they are accompanied by their demonymic equivalents, which denote hypothetical inhabitants of these bodies.
Saturn is named after the Roman god of wealth and agriculture, who was the father of the god Jupiter.Its astronomical symbol has been traced back to the Greek Oxyrhynchus Papyri, where it can be seen to be a Greek kappa-rho ligature with a horizontal stroke, as an abbreviation for Κρονος (), the Greek name for the planet ().

The name of Eris's moon Dysnomia was suggested by its discoverer Michael E. Brown, who also suggested the name of the dwarf planet. The name has two meanings: in mythology Dysnomia (lawlessness) is the daughter of Eris (chaos). However, the name is also an intentional reference to the actor Lucy Lawless who plays the character Xena. The ...
The Great White Spot, also known as Great White Oval (named by analogy to Jupiter's Great Red Spot) is a series of periodic storms on the planet Saturn that are large enough to be visible from Earth by telescope by their characteristic white appearance. The spots can be several thousands of kilometers wide.
Poseidon was also an unofficial name for Jupiter's moon Pasiphae 1955–1975. Jupiter and 5731 Zeus, discovered 1988. Uranus [2] and 30 Urania, discovered 1854. Uranus, however, is mostly named after the Greek god personifying the sky. There was a potential conflict between Saturn and Cronus, a suggested name for Pluto, discovered 1930.
Earth may have had a ring made up of a broken asteroid over 400 million years ago, a study finds. The Saturn-like feature could explain a climate shift at the time.
The solar wind is observed to exist in two fundamental states, termed the slow solar wind and the fast solar wind, though their differences extend well beyond their speeds. In near-Earth space, the slow solar wind is observed to have a velocity of 300–500 km/s , a temperature of ~ 100 kilokelvin and a composition that is a close match to the ...
As with Earth's magnetosphere, the boundary separating the solar wind's plasma from that within Saturn's magnetosphere is called the magnetopause. [2] The magnetopause distance from the planet's center at the subsolar point [ note 1 ] varies widely from 16 to 27 R s (R s =60,330 km is the equatorial radius of Saturn).
