What is our gas planets?
The four gas giants in our solar system are Neptune, Uranus, Saturn, and Jupiter. These are also called the Jovian planets.
What are the gas planets mostly made of?
hydrogen
A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune.
What is the difference between rocky and gas planets?
A gas giant planet is large enough that it retains a lot of hydrogen and helium. A rocky planet is one with a solid surface. That’s the rule of thumb to distinguish between the rocky and gaseous planets. But gaseous planets can have a solid core and rocky planets can have a very thick atmosphere.
How did the rocky planets form?
The formation of rocky planets happens over billions of years, through a process called accretion. As the pressure and temperature rise the elements that have been accreted heat up, melt, and differentiate, with heavier elements sinking to the core of the planet and lighter elements floating to the surface.
How are gas planets different from stars?
Stars are sources of energy; they emit light and heat created through nuclear fusion of hydrogen and helium in their cores. In contrast, planets have no renewable source of energy and cool off slowly through time.
How are the inner planets formed?
The first four planets Mercury, Venus, Earth and Mars, also called the inner planets are formed by rocks. While the outer planets (Jupiter and beyond) are composed mostly of gas.

What are the stages of planet formation?
Scientists believe that terrestrial planets, like Earth, formed by clumping together from dust and gas into into hot blobs of molten metal and rock several billion years ago. After becoming distinct planets, they went through four stages of formation: Differentiation, Cratering, Flooding and Surface Evolution.
What is planet formed first?
While all of the planets in our solar system are about the same age, it is widely believed that Jupiter formed first, about one million years after the Sun. Jupiter is the fifth planet from the Sun and is significantly larger than all the other planets in our solar system – it is more than twice as massive as all the other planets combined.
