The four gas giants are Jupiter, Saturn, Uranus and Neptune.
The outer planets include: Jupiter, Saturn, Uranus, Neptune, and Pluto (a dwarf planet). They are mostly huge (besides Pluto) and mostly gaseous.
we call huge planets huge planets
The four inner planets are smaller than the four outer planets. The inner planets are made up mostly of iron and various types of rock. The outer planets are mostly hydrogen, helium, and ice. The inner planets each completely rotate in less than an earth day. The inner planets all rotate faster than the outer planets.
The Rocky Planets are:MercuryVenusEarthMarsPluto (considered to be rocky most of the time)The Gaseous Planets are:JupiterSaturnUranusNeptuneThe first four planets (Mercury, Venus, Mars, and Earth) are called the inner planets which are closer to the sun and stripped of their light gasses by the sun's solar winds. The solar winds then carry the debris (elements) to where the winds tend to "die down" which is right near Jupiter. Thus, all the debris is mostly swept up by Jupiter and Saturn (which is why they appear so large), however, Uranus and Neptune are less gaseous because they are just so far away from the sun. Therefore, the first four planets are dense with a hard iron core, whereas the last four planets are gaseous and BIG.
Terrestrial planets have a rocky surface with a possible gaseous atmosphere. Like Earth. A gaseous planet like Jupiter is made up of mostly gas. What exactly is at the core is hard to determine since the pressures at the center are so huge, strange stuff happens like Hydrogen turning into a liquid.
A huge mass of stars and planets is called a galaxy.
Its super huge, super hot, and it is considered to be in the center of the planets orbits.
Jupiter is gaseous because it is predominantly made up of hydrogen and helium, the two most abundant gases in the universe. Its large size and mass, along with its distance from the Sun, allow it to retain these gases in their gaseous state rather than forming solid or liquid layers like terrestrial planets.
Earth and Mars.
All the 8 planets initially after the formation of the solar system were in the form of gas. But later on as the time passed the inner planets cooled down and their surface turned hard. But the remaining 4 planets are in their gaseous state till present. First of all they have got many moons orbiting around them They have got huge gravitational force they are bigger than the inner planets None of their surfaces shall solidify in the future.
The suns huge gravitational force keeps the planets in an orbit around it.
Well, there are two types planets in our solar system. Four rocky planets and four huge gas planets. Go to any planet chart add up the rocky planets size and divide that by four. Now, do the very same thing with the gas planets Viola!!!
