A general rule of thumb for planetary science is the further the planet is from it's star, the longer it's orbital period.

How do inner planets differ?

Inner planets differ from outer planets because they have rocky core (excepting Pluto), and the are much smaller than outer planets, which are bigger and take more time to orbit Sun than inner planets because of their location. Outer planets are farther from the Sun than inner planets.


How are the inner and outer planets alike?

The inner and outer planets are alike in that they are all part of our solar system and orbit around the Sun. They also have varying sizes and compositions, with the inner planets being smaller and rocky while the outer planets are larger and gaseous. Additionally, they all have moons, but the outer planets tend to have more and larger moons compared to the inner planets.


What are two similarities about the inner and outer planets?

Both inner and outer planets orbit around the sun and have roughly spherical shapes. Additionally, they are part of the same solar system and are composed of similar elements, such as rock and metal for inner planets, and gas and ice for outer planets.


How are inner and outer planets the same?

The inner planets are Mercury, Venus, Earth and Mars, while the outer planets are Jupiter, Saturn, Uranus and Neptune. They are the same in that they are spherical, the orbit the Sun in the same direction and they have an elliptical orbit.


Do the outer planets circle the inner planets?

All planets circle the CEntral Star. So in a way outer planets almost circle inner planets but the Star is at one focus of the planets' orbits so it is more proper to say that planets orbit stars.


What are some similarities of the inner and outer planets?

Inner and outer planets have some things that are in common but there mostly way different. For instants they both orbit the sun. On the other hand the outer planets are made mostly by gas, that's why they are called the gas giants. The inner planets are mostly made by rock and dust. The inner planets are called Terrestrial planets and the outer planets are called Jovian planets. The inner planets are closer to the sun, have more density, they have less moons, there about the size of Earth, and they rotate slowly. The outer planets (Jovian Planets) are farther from the sun, they have less density, they have more moons, they are large, about the size of Jupiter, they rotate rapidly, and they have more mass. These planets are alike because they both orbit the sun.


How do the orbits of the outer planets compare to the inner ones?

The outer planets take much more time and also travel longer to complete a whole orbit around the Sun, than the inner ones.


Do the inner planets or the outer planets get more of the sun's energy?

the inner planets


What are three ways that the inner planets are different from the putter planets?

The inner planets are rocky, with distinct solid surfaces, and dense, whereas the outer planets are gaseous, have no solid surface and are relatively light in comparison. The density of Saturn, for example, is less than that of water.


How do the inner planets travel around the sun than the outer planets?

The inner planets (Mercury, Venus, Earth, Mars) have shorter orbits and faster speeds, completing their orbits in less time than the outer planets (Jupiter, Saturn, Uranus, Neptune). The inner planets are closer to the sun, so they experience stronger gravitational forces that cause them to orbit more rapidly, while the outer planets move more slowly due to their greater distance from the sun.


Comparing inner and outer planets movement?

The inner planets travel faster around the Sun because they are closer, while the outer planets take more time. The outer planets spin faster on their axis than the inner planets.


Are the outer planets lighter than the inner planets?

No, the outer planets are not lighter than the inner planets. In fact, the outer planets are generally much larger and more massive than the inner planets. This is because they are primarily composed of gases and ice, which makes them less dense but more massive.
