A giant planet, sometimes referred to as a jovian planet (Jove being another name for the Roman god Jupiter), is a diverse type of planet much larger than Earth. Giant planets are usually primarily composed of low- boiling point materials (volatiles), rather than rock or other solid matter, but massive solid planets can also exist.
Jupiter is the largest planet in our solar system. If Jupiter was a hollow shell, 1,000 Earths could fit inside. Jupiter also is the oldest planet, forming from the dust and gases left over from the Sun's formation 4.5 billion years ago.
The giant planets are very far from the Sun. Jupiter is more than five times farther from the Sun than Earth’s distance (5 AU), and takes just under 12 years to circle the Sun. Saturn is about twice as far away as Jupiter (almost 10 AU) and takes nearly 30 years to complete one orbit.
Describe the composition and structure of Jupiter, Saturn, Uranus, and Neptune. Compare and contrast the internal heat sources of the giant planets. Describe the discovery and characteristics of the giant planets’ magnetic fields. Let us now examine the four giant (or jovian) planets in more detail.
Which planet is biggest? Which is smallest? What is the order of the planets as we move out from the Sun? This is a simple guide to the sizes of planets based on the equatorial diameter – or width – at the equator of each planet. Each planet’s width is compared to Earth’s equatorial diameter, which is about 7,926 miles (12,756 kilometers).
Our solar system has four giant planets: Neptune, Uranus, Saturn, and Jupiter. Giant planets are much larger than Earth—they are unimaginably huge, stunningly beautiful, and sometimes a little weird.
…also called the Jovian, or giant, planets—Jupiter, Saturn, Uranus, and Neptune—are large objects with densities less than 2 grams per cubic cm; they are composed primarily of hydrogen and helium (Jupiter and Saturn) or of ice, rock, hydrogen, and helium (Uranus and Neptune).
The outer solar system contains the four giant planets: Jupiter, Saturn, Uranus, and Neptune. The gas giants Jupiter and Saturn have overall compositions similar to that of the Sun and have been explored by the Pioneer, Voyager, Galileo, and Cassini spacecraft.
Jupiter is the fifth planet from our Sun and is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter's stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium.
Saturn is the sixth planet from the Sun and the second largest planet in our solar system. Adorned with a dazzling system of icy rings, Saturn is unique among the planets. Saturn is a massive ball made mostly of hydrogen and helium.
