what is the difference between rocky and gas planets?
604608
The atmospheric characteristics of rocky and gas planets differ. ... The terrestrial planets in the solar system have atmospheres made up mostly of gases such as carbon dioxide, nitrogen and oxygen. The gas giants, on the other hand, consist mainly of lighter gases like hydrogen and helium.

The main difference between stars and planets is that stars have high temperatures compared to planets. ... Because they radiate energy, stars are very bright objects. Planets do not generate their own energy through nuclear reactions. They reflect some of the radiation coming from their parent star.

There are the inner, rocky terrestrial planets and then the outer gas giants. Venus is a terrestrial planet. ... The main difference between Earth and Venus is the incredibly thick carbon dioxide atmosphere, which raises temperatures on the surface of Venus to the point that it's hot enough to melt lead.

The outer planets are also called the Jovian planets or gas giants. Like the inner planets, the outer planets have similar characteristics to one another. The outer planets are so much larger than the inner planets that they make up 99 percent of the mass of the celestial bodies that orbit the Sun.

Their main difference is their composition. Terrestrial planets are covered with solid surfaces while jovian planets are characterized by gaseous surfaces. These terrestrial planets in our solar system are Mercury, Venus, Earth, and Mars. The jovian planets are Jupiter, Saturn, Uranus, and Neptune.

After Mars, there is an asteroid belt that separates the inner planets from the outer ones. The outer planets are called the jovian planets, meaning huge gas giant. These planets in order are Jupiter, Saturn, Uranus, and Neptune. ... Size is the most obvious difference between the inner and outer planets.

Inner planet are closer to the sun hence,the heat from the sun evaporates the gases like hydrogen or helium. so only heavy weight dense metals such as iron,magnesium were left thus,the surface becomes rocky. whereas,if you see outer planets,they have a thick envelope of lightweight gases.

In our solar system, gas giants are much bigger than terrestrial planets, and they have thick atmospheres full of hydrogen and helium. On Jupiter and Saturn, hydrogen and helium make up most of the planet, while on Uranus and Neptune, the elements make up just the outer envelope.

Gas giants are large planets that contain more than 10 times the mass of Earth, they are also known as the Jovian or Outer Planets. Their compositions are mostly gases, such as hydrogen, and small amounts of rocky material (mostly at their cores).

In our Solar System, astronomers often divide the planets into two groups — the inner planets and the outer planets. The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas.

If its mass is great enough for fusion to occur, it's a star. So the biggest difference between a star and a planet is that a sun is massive enough for fusion.

The Inner and Outer Planets in Our Solar System. ... The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.

How do the outer planets differ from the inner planets? Outer planets differ from inner planets in composition, size, distance, and mass. Outer planets are made of gases rather than rock and metal like inner planets. Unlike inner planets, outer planets are larger and spaced farther apart.

The four inner planets, or terrestrial planets, have solid, rocky surfaces. Mercury is the smallest planet and the closest to the Sun. It has an extremely thin atmosphere, with surface temperatures ranging from very hot to very cold.
577448
They are called the inner planets. The inner planets are made up mostly of rock. The outer planets are Jupiter, Saturn, Uranus, and Neptune. Jupiter, Saturn, Uranus, and Neptune are large balls of gases with rings around them.
233025
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.

Summary. The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
