Difference between inner and outer planets

• Categorized under Physics,Science | Difference between inner and outer planets


Our solar system consists of countless planets, among which is Earth. The total variety of planets is eight back there have been arguments to this statement through some saying over there are an ext than eight (the opponents of the concept that Pluto is no a planet). Everything the case, once we talk about planets we division them into two groups; inner planets and also outer planets. This classification is loved one to the planets’ place with respect to the Sun. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and also Neptune. Us shall now make clean which of these room inner planets and which are external planets and what actually differentiates them.

You are watching: How do the inner planets differ from the outer planets

Inner planets are those planets which room closest come the sun and include the first four planets (Mercury, Venus, Earth and Mars) in stimulate of increasing distance indigenous the Sun. Mercury is the closest, adhered to by Venus, Earth and then Mars. External planets room those which are more away native the Sun and include the next four planets in order of boosting distance from the sunlight (Jupiter, Saturn, Uranus and Neptune), v Neptune being the furthest.

The within planets are consisted of of rock and metal and also are therefore solid. This planets move slowly as lock are thought about to it is in heavy. They have an mean diameter of around 13000 km as castle are small planets. On the other hand, the external planets are stated to it is in made the gases and also they space not yes, really solid. The gases which make them up space Hydrogen and Helium; large balloons floating in the space are considered as huge gas planets by people and they have an mean diameter of about 48000 km.

Furthermore, the inner planets room warmer than external planets simply as result of the reality that they are closer to the Sun. Outer planets space composed the lighter aspects such as gases and also inner planets space composed that heavy aspects such together iron. Inside planets have fewer moons, small, silicate surface, nickel-iron core, higher density and rotate an ext slowly contrasted to outer planets. External planets have a greater number of moons, no hard part; revolve faster, have actually a lower density and rings in some situations (Jupiter and also Saturn). External planets are substantially bigger than the within planets as Jupiter is measured to be 88846 miles in diameter and also Mercury is measured to it is in 3031 mile in diameter.

There is far-reaching difference between the rotation and also the orbit of the two types of planets. Because that example, for Jupiter it would take 9 hours and 55 minutes because that a day to finish (or to finish one rotation) and on Venus it would certainly take 234 hrs for a day come complete. (The time duration of a day is that compared to the standard 24 hour work on Earth.) The within planets take it lesser time to orbit the sunlight whereas the planets which are far away need much more time as they need to cover much more ground. Because that example, Jupiter take away 164 planet years to complete one orbit!


Inner planets are those which space closer come the sun (Mercury, Venus, Earth and Mars) and also outer planets space those i m sorry are more from the sun (Jupiter, Saturn, Uranus and Neptune)

Inner planets have fewer moons, small, silicate surface, nickel-iron core, higher density and also rotate slowly compared to external planets which have actually greater number of moons, much faster rotation, no heavy part, reduced density and rings (in the instance of Jupiter and Saturn)

Outer planets are significantly bigger 보다 the inside planets; Jupiter is measured to be 88846 mile in diameter and Mercury is measure to it is in 3031 miles in diameter

Outer planets spin quicker than inside planets which rotate slowly

For the within planets that takes lesser time to complete an orbit roughly the sun whereas external planets take better time as result of their better distance from the sunlight
