In both the ancient Greek and Roman civilizations, Jupiter was named after the chief god of the divine pantheon: Zeus to the Greeks and Jupiter to the Romans. [19] The International Astronomical Union formally adopted the name Jupiter for the planet in 1976 and has since named its newly discovered satellites for the god's lovers, favourites, and descendants. [20]
Similarly to Jupiter, Saturn is not likely to host life. It is a gas giant and the temperatures, pressures, and materials found in it are too dangerous for life. [63] The planet is hydrogen and helium for the most part, with trace amounts of ice water. Temperatures near the surface are near -150 C.
Saturn is the sixth planet from the Sun and the second largest in the Solar System, after Jupiter. It is a gas giant , with an average radius of about nine times that of Earth . [ 27 ] [ 28 ] It has an eighth the average density of Earth, but is over 95 times more massive.
Some of these bodies have exactly the same name, referring to the same mythological character. The earliest such conflicts possibly arose through not considering certain mythological names as "official"; for instance, the names Io, Europa, Ganymede and Callisto for the Galilean satellites of Jupiter were not used in astronomical literature of a certain era, their place being taken by Jupiter I ...
Jupiter on Saturday will shine at its brightest for the year, as Earth’s orbit swings our planet between Jupiter and the sun. Weather permitting, the gas giant will not only be brighter than ...
The smallest known extrasolar planet that is likely a "gas planet" is Kepler-138d, which has the same mass as Earth but is 60% larger and therefore has a density that indicates a thick gas envelope. [16] A low-mass gas planet can still have a radius resembling that of a gas giant if it has the right temperature. [17]
Astronomers have identified a planet that’s bigger than Jupiter yet surprisingly as fluffy and light as cotton candy. The gas giants in our solar system — Jupiter, Saturn, Uranus and Neptune ...
Io (Jupiter I) is the innermost of the four Galilean moons of Jupiter; with a diameter of 3642 kilometers, it is the fourth-largest moon in the Solar System, and is only marginally larger than Earth's moon. It was named after Io, a priestess of Hera who became one of the lovers of Zeus. It was referred to as "Jupiter I", or "The first satellite ...
