The "outer planets" refers to the four farthest planets from the Sun (the four largest planets, all gas giants) : Jupiter, Saturn, Uranus and Neptune. Pluto, once considered the ninth planet, is currently classed as a dwarf planet.
Memory Aid
The mnemonic "My Very Excited Mother Just Served Us Nachos" can provide the names and order for all of the planets : "Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune".
Jupiter, Saturn, Uranus, Neptune.
The inner planets, which are closest to the Sun, are:MercuryVenusEarthMarsThe outer planets, which are farther away from the sun are:JupiterSaturnUranusNeptune
The order of the outer planets, from closet to the sun to furthest away from the sun, is Jupiter, Saturn, Uranus, then Neptune.
The outer planets generate their own heat and the inner planets are warmed by the sun.
Inner planets travel faster than outer planets
The outer planets take longer.
The inner planets, which are closest to the Sun, are:MercuryVenusEarthMarsThe outer planets, which are farther away from the sun are:JupiterSaturnUranusNeptune
The outer planets take longer to orbit the Sun, because they are farther away from the Sun. It make its gravitational pull weaker to the farther planets. That means that the outer planets take longer to orbit the Sun.
The inner planets are hotter because they are the closest to the sun the outer planets are the coldest because they are the farthest planets from the sun
The order of the outer planets, from closet to the sun to furthest away from the sun, is Jupiter, Saturn, Uranus, then Neptune.
Outer planets are gas planets and they are outside the astroid belt and are further away from the sun.
They are similar in that both the inner and outer planets all orbit the sun.
the inner planets are closest to the sun and the outer planets are farthest from the sun { Answered by a grade 4 student}
Inner planets travel faster than outer planets
The outer planets generate their own heat and the inner planets are warmed by the sun.
They follow orbital paths which, like those of the inner planets, are centered on the sun, but the outer planets, without exception, are farther from the sun than any of the inner planets is.
The outer planets take longer.
