Giant planets are also called “Jovian Planets”.The term Jovian comes from Jove, the king of the gods in Roman mythology, and also the early name of Jupiter. Therefore, Jovian describes the other giant planets as being Jupiter-like. All Jovian planets were also once known as “...
Today, Gas giants are divided into five classes, based on the classification scheme proposed by David Sudarki (et al.) in a 2000 study. Titled “Albedo and Reflection Spectra of Extrasolar Giant Planets“, Sudarsky and his colleagues designated five different types of gas giant based on their ...
the planets of theinner Solar Systemare smaller and denser than the gas/ice giants of theouter Solar System. And in some cases, planets can actually be smaller than the largest moons. But a planet’s size is not necessarily proportional to its mass. In the end...
Auroras occur on other planets, too — all that's required to make an aurora is an atmosphere and a magnetic field. "Auroras have been seen in the atmospheres of all the gas giant planets, which is not surprising, since these planets all have robust magnetic fields," said Jeff Regester,...
Planetary migration explains why the majority of giant planets discovered elsewhere in the galaxy don't stay in their distant orbits. As they form, they spiral inwards towards their star.行星迁移解释了银河系其他地方发现的大多数巨型行星不会停留在它们遥远的轨道上的原因。当它们形成的时候，它们向呈内...
as having a kind of miniature solar system. The fifth planet from the sun, Jupiter is considered a gas giant because it has no solid surface. It is mainly composed of hydrogen and helium. The planet's colorful clouds are created by jet streams and huge, intense storms, such as the Great...
Professor: Yes, it need to be the right temperature to sustain liquid water. Student: And it would need to be a rocky planet, I mean, as opposed to a gas giant. Professor: OK, good. An Earth-like planet. Now, as to that, there are some recently detected exoplanets that might actual...
Pluto has numerous moons but is not a planet in the same sense as Earth. Also, Mercury has no moons but is a fully-fledged planet like Earth. All the gas planets, including Jupiter and Neptune, have rings of dust. Jupiter's and Neptune's rings are not as big as those of Saturn ...
At present only one of these planets has been found to transit the face of its parent star. Its radius is that of a slightly inflated gas giant. Models of the structure and evolution of these planets are beginning to show how clues to their evolutionary history may be encoded in their ...
MALE STUDENT:# And it would need to be a rocky planet…. I mean, as opposed to a gas giant…. MALE PROFESSOR: OK, good. An Earth-like planet. Now, as to that, there are some recently detected exoplanets that might actually be Earth-like. ...
