A gas giant is a large planet composed mostly of gases, such as hydrogen first formed as rocky and icy planets similar to terrestrial planets. In our solar system, Jupiter, Saturn, Uranus and Neptune are gas giants, also known as jovian planets. It's unclear what the dividing line is between a rocky planet and a terrestrial planet; some super-Earths may have a liquid surface, for example. This activity will emphasize that the planets fall into two compositional groups: the terrestrial (rock-like) planets (Mercury, Venus, Earth, Mars, and Pluto) and the gas planets (Jupiter, Saturn, Uranus, and Neptune).
A terrestrial planet, telluric planet, or rocky planet is a planet that is composed primarily of Most of the planets discovered outside the Solar System are giant planets, because they are more easily detectable. and Neptune's; super-Earths may be gas planets or terrestrial, depending on their mass and other parameters. Unlike terrestrial planets whose composition is rocky, gas giants have a mostly gaseous composition, such as hydrogen and helium. They do have some rocky material, although this is most often found in the planet core. The four gas giants are (in order of distance from the Sun): Jupiter, Saturn, Uranus, and Neptune. The goal of planetary astronomy is to understand both the differences and the similarities (called comparative planetology) of the major objects in the solar sy.
The four inner planets are called terrestrial planets because their The outer planets (sometimes called Jovian planets or gas giants) are huge. What they found was that gas giant planets were more likely to form around metal rich stars, whereas terrestrial planets were equally likely to. Given time, such a mix would result in a giant gas planet with a solid that Super -Earths and other terrestrial planets could, in fact, be the cores.
