Jovian and Terrestrial planets
Terrestrial Planets
They include Mercury, Venus, Earth, and Mars.
These planets are relatively small in size and in mass.
Inner Planets
A terrestrial planet has a solid rocky surface, with metals deep in its interior.
These planets are closer to the sun and are therefore warmer than the planets located farther out in the solar system.
The atmospheres of the terrestrial planets range from thin to thick.
Mercury has almost no atmosphere.
A thick atmosphere made mostly of carbon dioxide covers Venus, trapping heat and raising surface temperatures.
Clouds on Venus form from sulfuric acid.
Earth's atmosphere is 77 percent nitrogen, 21 percent oxygen, and 1 percent argon, with variable amounts of water vapor, and trace amounts of other gases. White clouds of water vapor hide much of Earth's surface in views of Earth from space.
Mars has a very thin atmosphere containing mostly carbon dioxide, with nitrogen, argon, and trace amounts of oxygen and water vapor. The atmosphere also contains thin water and carbon dioxide clouds, and is frequently affected by dust storms.
Jovian Planets
Outer Planets
Jovian planets include Jupiter, Saturn, Uranus, and Neptune.
These planets have larger sizes and masses.
Jovian planets do not have solid surfaces.
They are sometimes called gas giants because they are large and made mostly of gases.
Small amounts of rocky materials are only found deep in the cores of Jovian planets.
In the solar system, Jovian planets are located farther from the sun than terrestrial planets, and are therefore cooler.
Scientists have found more than 100 Jovian planets around other stars.
The majority of the extrasolar Jovian planets that have been discovered so far are closer to their stars than the Jovian planets in the solar system are to the sun.
The atmospheres of the Jovian planets in our solar system are made mostly of hydrogen and helium. Compounds containing hydrogen, such as water, ammonia, and methane, are also present.
Differences in the amounts of these trace gases and variations in the temperatures of these planets contribute to the different colors seen in images taken in visible light.
They have a long period of revolution around the sun
They are much farther apart than the inner planets.
Similarities
They are all planets
They all orbit the sun
Most of them have moons
They all rotate on the axis
