What separates the inner planets from the outer planets?

Answer 1

Nothing officially separates them but most asteroids are between Mars and Jupiter.
There is no planet separating the Outer planets. Outer planets are Jupiter, Saturn, Uranus and Neptune and this are gas giant. Asteroid belt consists of asteroid and Ceres, the Dwarf planet so an Dwarf planet and Asteroid belt separates the Planets.

Answer 2

Nothing really separates the planets into groups. If you are referring to the outer planets as the gas giants Jupiter, Saturn, Uranus, and Neptune. With the inner planets Mercury, Venus, Earth, Mars. Then the difference is simply their masses. If you are referring to the asteroid belt between Mars and Jupiter, there is speculation and theory with one being that the belt is a failed planet that never coalesced.

The above is not the correct answer to the question.

The question is asking "What separates the outer planets from the inner planets," in other words, "What divides the two?"

To answer, it is the asteroid belt.

All discussion is welcome, and I stand my case. I mentioned if the the question might refer to the asteroid belt while also posing a possible theory about the origin of the belt drawing from knowledge of Johannas Kepler. That area of our solar system exists just as orbital regions around Saturn does. I personally do not think of it as separation because it is one part of the entire structure.

Put this way, what if the belt was not there, or there was instead a planet? would you still call it a separation? I do not mean to be confrontational, just literal. I welcome your feedback.

I am now wondering where the term inner and outer planets really came from?

Answer 3

The line that divides the Inner Planets (Mercury, Venus, Earth, and Mars) from the Outer Planets (Jupiter, Saturn, Uranus, and Neptune) is not really a solid line; it is a set of asteroids that form something like a line. It is called the asteroid belt.

Answer 4

Rather than "inner" and "outer" planets, the planets are categorized as "inferior" and "superior" based on their mean orbital radius around the come, compared to Earth's orbit. Planets which orbit with a radius smaller than Earth's are inferior planets; those orbiting outside Earth's orbit are superior planets.

Mercury and Venus are inferior planets. Mars, Jupiter, Saturn, Uranus and Neptune are superior planets.

Answer 5

The boundary that separates the inner planet from the outer planet are asteroid belt

The boundary that separates the inner planet from the outer planet are asteroid belt

Answer 6

The area of the asteroid belt can be thought of as a dividing line between two groups of planets, the inner and outer planets.

Answer 7

an asteroid belt

Answer 8

Distance. And lots of it.
