they move because of space eruptions
Yes. All planets move in orbit around their host star.
They move because of the gravitational pull of the sun.
none of the inner planets
The inner planets are Mercury, Venus, Earth, and Mars. They are "inner" because the are the first 4 planets from the Sun.

Inner planets are terrestrial planets outer are jovian planets
the inner planets
I hesitate to admit that I was raised on one of the inner planets. The inner planets are not gaseous, like the outer planets.
As planets move from outer to inner planets, their periods of revolution decrease. This is because the inner planets are closer to the Sun, so they have shorter orbital paths and complete their revolutions more quickly. Outer planets, being farther from the Sun, take longer to complete their journeys around it.
outer planets are gas giants whille inner planets are just rocky planets. that includes that outer planets have significant amount of mass than the inner planets
