they are not. smaller planet can be farther..
Initially the sun was surrounded by a disk of gas, it was probably denser towards the middle. The planets formed from this gas. A small fraction of the gas could condense to form rock and metal, which then sank to the centre of the gas planets. The inner planets have had their gas blown away by the solar wind, leaving only the rocky core, perhaps with a thin atmosphere. The Middle planets (Jupiter and Saturn) have kept all their gas and so are much larger. The Outer planets (Uranus, Neptune) formed from part of the original disk that was thinner and so they are somewhat smaller than Jupiter.
Beyond Neptune their are only icy remenants, In that region was beyond the main disk that formed the solar system there are only very small (dwarf) planets there.

Why does it take the outer planets so long to orbit the Sun?
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.
What happens to the length of the planet year as you move away from the sun?
I would define a "planetary year" as the time it takes to make one complete orbit around the sun. The farther from the sun you go the farther the distance one orbit is (larger radius = larger circumference). The length of the planetary year depends upon the distance from the sun and the orbital speed of the planet. This website has some handy information about the planets in our solar system. http:/wwwzperiodzenchantedlearningzperiodzcom/subjects/astronomy/planets -------------------------------------------------------------------------------------- It should be noted however that some farther away planets have shorter planetary years than earth and some closer planets have longer planetary years (due to orbital speed).
What are the two closest planets to Jupiter?
The two closest planets are Mars and Saturn. Mars is closer to the sun, Saturn is farther from the sun.
Why do gas giants generally lhave lower average temperaturers than the terrestrial planets?
they are farther from the sun
Do more massive planets take longer to orbit the sun?
The length of time it takes for a planet to orbit the sun is based on its distance from the sun, not its mass. The farther a planet is from the sun, the larger its orbital path, and the longer it takes to complete an orbit.
How do planets farther from the sun differ from that planets that are closer to the sun?
The four outer planets are gas giants - they are much larger than the four inner planets, and they consist mainly of gas - they don't have a surface on which you can stand.
Do planets tend to have more earth days the further they are from the sun?
Yes, planets that are farther from the sun have larger orbits and it takes then longer to revolve around the sun. Therefore, they have more earth days.
Is Pluto closer to the sun?
Pluto is farther from the sun than any of the 8 major planets. There are other dwarf planets farther from the sun than Pluto though.
How do the planets farther from the Sun differ from the planets that are closer to the Sun?
The farther away from the sun, the farther apart the orbits of the planets become (the planets farther away from the sun are more spaced out). The average distance between Mercury and Venus, the two closest planets to the sun, is about 0.779 au. The average distance from Mars to Jupiter, the two planets in the middle, is about 5.32 as. The average distance from Uranus to Neptune, the two planets farthest from the sun, is about 33.2 au.
Why does it take the pouter planets so long to orbit the sun?
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.
Can you differentiate the outer planets from the inner planets?
The inner planets, which are closest to the Sun, are:MercuryVenusEarthMarsThe outer planets, which are farther away from the sun are:JupiterSaturnUranusNeptune
Are the planets moving farther from the sun over time?
No.
Are gas planets closest or farthest from the sun?
farther
Why does it take the outer planets so long to orbit the Sun?
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.
Why is one planets air pressure greater than another planets?
It is because some of the planets are farther from the sun
Do the speed of the planets decrease when they are far from the sun?
They are going faster so they are farther from the sun.
How do the massive outer planets differ from the inner terrestrial planets?
#1 they are further away , by proportion , from the Sun. #2 they are composed of gases. (No hard surface)' #3 they are larger than the inner terrestial (rocky) planets (NB Jupiter is about 1,000 times larger than the Earth). #4 they take longer to orbit the Sun
