Do inner planets orbit the sun at higher speeds than outer planets?

They don't...
An inner planet such as Mercury has an orbital speed of 107,00 MPH when compared to the outer most "planet" Pluto which rotates at 10,500 MPH. The gravitational restraints of the sun is greater on the inner planets than the outer allowing them to rotate faster without flying off into space. It's simple physics, the concepts of Centrifugal Force.

∙ 14y agoThe outer planets all rotate faster than the inner planets. Each of them has a rotational period shorter than an Earth Day. All of the inner planets have rotational periods greater than one Earth day.

∙ 12y agoYes, all the planets in the Solar System orbit the Sun. If they didn't, they would drift out of the Solar System and would eventually become attracted towards the gravitational pull of another Star.

Mercury is 57.9 million km (36 million miles) from the Sun (0.38 AU)
Venus is 108.2 million km (67.2 million miles) from the Sun (0.72 AU )
Earth is 149.6 million km (93 million miles) from the Sun (1 AU)
Mars is 227.9 million km (141.6 million miles) from the Sun (1.52 AU)
OUTER PLANETS:
Jupiter is 778.4 million km (483.6 million miles) from the Sun (5.2 AU)
Saturn is 1.4 billion km (870 million miles) from the Sun (9.5 AU)
Uranus is 2.87 billion km (1.78 billion miles) from the Sun (19.2 AU)
Neptune is 4.5 billion km (2.8 billion miles) from the Sun (30 AU)

Looked at another way, if they were at that distance but not going fast enough, they would just fall into the Sun, so only the fast movers have survived.

∙ 9y agoThe inner planets are also called the stoney or rocky planets. The outer planets are called gas giants. Don't confuse density with mass. A ton of feathers has a greater mass than half ton of iron. So the inner planets are more dense than the outer planets, but the huge outer planets have more mass.
Wiki User
∙ 9y agoAlthough the average density of the four inner planets is more than four times the average density of the four outer planets, because the outer planets are so huge compared to the inner planets, the average mass of the outer planets is about 225 times the average mass of the inner planets.

∙ 11y agothe outer planets move more slower bbecause the orbits are bigger

What distinguish the inner and outer planets?
This is a very basic answer, but maybe it's what you're looking for. The inner planets are rocky, have no rings, and are smaller. The outer planets are large, gaseous, and have rings.
What is the main difference between the orbits of the inner outer planets?
the inner orbit faster
Why planets orbit the sun in different speeds?
it is different because the size.
What takes long to orbit the sun inner or outer planets?
The outer planets take longer.
Name of planets orbit closest to the sun?
The Inner Planets: Mercury, Venus, Earth and Mars
What distinguishes inner planets and outer planets?
Inner planets have a radius orbit shorter than the orbit of Jupiter. Outer planets are all the other planets of the solar system.
How are outer planets similar to inner planets?
They are similar in that both the inner and outer planets all orbit the sun.
How is Pluto not like the 4 inner planets?
Pluto is different from the inner planets in that it has not cleared it's orbit from asteroids.
What distinguish the inner and outer planets?
This is a very basic answer, but maybe it's what you're looking for. The inner planets are rocky, have no rings, and are smaller. The outer planets are large, gaseous, and have rings.
How are inner and outer planets the same?
The inner planets are Mercury, Venus, Earth and Mars, while the outer planets are Jupiter, Saturn, Uranus and Neptune. They are the same in that they are spherical, the orbit the Sun in the same direction and they have an elliptical orbit.
What is the main difference between the orbits of the inner outer planets?
the inner orbit faster
Why planets orbit the sun in different speeds?
it is different because the size.
What are two similarities about the inner and outer planets?
The inner planets, otherwise known as the terrestrial planets all are: -rocky/more dense (unlike the gaseous outer planets) -closest to the sun -smallest planets
What are inner and outer planets What is the difference?
In our solar system; Inner planets are planets that have an orbit which lies within the asteroid belt. Outer planets are planets which have an orbit which lies outside the orbit of the asteroid belt. The asteroid belt lies between Mars and Jupiter. Therefore the inner planets would be in order away form the sun, Mercury, Venus, Earth and Mars. The outer planets in the same order are; Jupiter, Saturn, Uranus and Neptune.
Do the inner planets have direct or in direct orbit?
All the planets have direct orbits round the Sun.
Do inner planets move?
Yes. All planets move in orbit around their host star.
How are inner planets and gas giants similar?
they orbit the sun and are the first four outer planets
