Differentiate between inner planets and outer planet of the solar system
The Correct Answer and Explanation is:
Correct Answer:
Inner planets are Mercury, Venus, Earth, and Mars, while outer planets are Jupiter, Saturn, Uranus, and Neptune. Inner planets are smaller, rocky, and located closer to the Sun. Outer planets are larger, mostly made of gases, and are farther from the Sun.
Explanation:
The solar system is divided into two groups of planets based on their position relative to the Sun and their physical characteristics. These are the inner planets and the outer planets.
Inner planets include Mercury, Venus, Earth, and Mars. They are also called terrestrial planets because they have solid, rocky surfaces. These planets are smaller in size compared to the outer planets. They have higher densities and relatively few or no moons. For example, Mercury and Venus do not have any moons, while Earth has one and Mars has two. Inner planets are located closer to the Sun and have shorter orbital paths, which means they take less time to complete a revolution around the Sun. Due to their proximity to the Sun, their temperatures tend to be higher. They also have slower rotation speeds and relatively weaker magnetic fields.
Outer planets include Jupiter, Saturn, Uranus, and Neptune. These are also known as gas giants, except for Uranus and Neptune which are sometimes classified as ice giants because of their higher concentration of icy materials. Outer planets are much larger than inner planets and mostly consist of hydrogen, helium, and other gases. They have thick atmospheres, many moons, and ring systems. Jupiter, for example, has over 90 known moons. These planets are located farther from the Sun, have much longer orbital periods, and colder surface temperatures. Their rotation speeds are faster, and their magnetic fields are much stronger.
In summary, the inner planets are small, rocky, and close to the Sun, while the outer planets are large, gaseous, and far from the Sun. This classification helps scientists understand the structure and evolution of our solar system.
