"These structures are huge storms. Some such spots are thunderheads as well. Giant planet A giant planet is any massive planet. They are usually primarily composed of low-boiling-point materials (gases or ices), rather than rock or other solid matter, but massive solid planets can also exist. There are four known giant planets in the Solar System: Jupiter, Saturn, Uranus and Neptune. Many extrasolar giant planets have been identified orbiting other stars. Giant planets are also sometimes called jovian planets, after Jupiter (""Jove"" being another name for the Roman god ""Jupiter""). They are also sometimes known as gas giants. However, many"

In recognition of his achievement, King George III gave Herschel an annual stipend of £200 on condition that he move to Windsor so that the Royal Family could look through his telescopes.

The official naming citation was mentioned in ""The Names of the Minor Planets"" by Paul Herget in 1955 (). Demeter is the Greek equivalent of the Roman goddess Ceres. When main-belt asteroid and dwarf planet 1 Ceres was named, the Greeks called it ""Demeter"" effectively translating the name into Greek, rather than using the Latin ""Ceres"" or the original Italian ""Cerere"". However, this created a problem when asteroid ""Demeter"" was named. The Greeks resolved this by using the classical form of the name, Δημήτηρ"
"When subsequent planets were discovered in the 18th and 19th centuries, the naming practice was retained with ""Neptūnus"" (Poseidon). Uranus is unique in that it is named for a Greek deity rather than his Roman counterpart. Some Romans, following a belief possibly originating in Mesopotamia but developed in Hellenistic Egypt, believed that the seven gods after whom the planets were named took hourly shifts in looking after affairs on Earth. The order of shifts went Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon (from the farthest to the closest planet). Therefore, the first day was started by Saturn (1st hour), second"
