They don't...
An inner planet such as Mercury has an orbital speed of 107,00 MPH when compared to the outer most "planet" Pluto which rotates at 10,500 MPH. The gravitational restraints of the sun is greater on the inner planets than the outer allowing them to rotate faster without flying off into space. It's simple physics, the concepts of Centrifugal Force.
This is a very basic answer, but maybe it's what you're looking for. The inner planets are rocky, have no rings, and are smaller. The outer planets are large, gaseous, and have rings.
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.
The outer planets take longer.
They are closer to the star they circulate around or the other planets and so their centre of gravity is closer, therefore the force is stronger and thus causing their rotation to increase in speed.
Planets orbit the sun at different speeds because they are at varying distances from the sun. According to Kepler's laws of planetary motion, planets closer to the sun have faster orbital speeds, while those farther away have slower speeds. This is due to the gravitational force exerted by the sun, which is stronger on planets closer to it.
Inner planets have a radius orbit shorter than the orbit of Jupiter. Outer planets are all the other planets of the solar system.
They are similar in that both the inner and outer planets all orbit the sun.
Pluto is different from the inner planets in that it has not cleared it's orbit from asteroids.

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.
In our solar system; Inner planets are planets that have an orbit which lies within the asteroid belt. Outer planets are planets which have an orbit which lies outside the orbit of the asteroid belt. The asteroid belt lies between Mars and Jupiter. Therefore the inner planets would be in order away form the sun, Mercury, Venus, Earth and Mars. The outer planets in the same order are; Jupiter, Saturn, Uranus and Neptune.
they orbit the sun and are the first four outer planets
The outer planets take longer.
Yes. All planets move in orbit around their host star.
All the planets have direct orbits round the Sun.
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.
