∙ 7y agoBecause the inner planets are made of rock but the outer planets are made of gas(except for Pluto).
Very simple. We have 2 asteroid belts in our Solar System that divides the inner planets and outer planets. Very well organized and place you can tell with is the inner (closet to the sun) and which is outer (farther from the sun).
they are all gas giants
The planets in the solar system can be sorted to two types: inner planets that are the four closer planets to the Sun, which are rocky and small. And outer planets which are the four other planets which are gaseous and very large.
The 4 Inner planets (mostly rocky and solid):MercuryVenusEarthMarsThe 4 Outer planets (mostly dense gaseous atmospheres):JupiterSaturnUranusNeptuneNotes:Pluto, a dwarf planet, was an outer planet before it got reclassified, but resembles the inner planets.The inner and outer planets are separated by the asteroid belt.When dwarf planets are included, Ceres counts as an inner planet and all the other dwarf planets count as outer planets.
They have in common is that they are the last planets in the solar system
The outer plants are made out of gases mostly.
they are apart of the solar system
The outer planets are primarily gaseous meaning they are basically just gargantuan masses of gas.
they al are outer planets.
The outer (major) planets of our solar system are the 4 gas giants:JupiterSaturnUranusNeptuneFurthermore, 4 out of the 5 dwarf planets are also in the outer solar system, beyond the orbit of neptune:PlutoHaumeaMakemakeEris
