-- If different parts of the Earth revolved around the sun at different speeds,

then the Earth would have to come apart in pieces. They don't, and it doesn't.

-- The tropical year is the same duration everywhere on Earth.

Why do the outer planets revolve around the sun slower?

The outer planets revolve around the sun slower because they are farther away from the sun, which means they have a greater distance to travel in their orbits. According to Kepler's laws of planetary motion, planets that are farther from the sun have longer orbital periods.


How does the distance from the sun effect planets orbit?

In general, the planets that are farther from the Sun move slower, and take longer to go around the Sun. The quantitative relationship (i.e., exactly how much slower) is expressed by Kepler's Third Law.


When Neptune orbits around the Sun is it faster or slower than earth?

Neptune moves more slowly than Earth. The farther a planet is from the Sun, the longer its orbit. But the lesser gravity of the Sun at longer distances means that the planets also do not need to move as rapidly in their orbits. A planet farther from the Sun moves more slowly than one closer to the Sun.


Is a year on mars longer or shorter on earth?

Mars orbits farther from the sun,tthan Earth does, meand its orbital circumference is longer. Additionally, the farther out an orbiting object is, the slower it travels. So, to complete one orbit, Mars has to travel farther than Earth does and at a slower speed.


Why do the planets further the sun have longer years?

The farther a planet is from the sun, the farther it has to go on its way around.Also . . . the way gravity works, a planet farther from the sun will move slower in its orbit.So when you add it up . . . moving slower plus a longer way to go . . . the farther ones take longer for each revolution.


Which planet has the slower orbital speed Saturn or Jupiter?

Saturn is slower because it is farther from the sun. The farther away a planet is from the sun, the slower its orbital speed.


Why Saturn year bigger?

Because it takes longer and slower to go around the sun therefor making it a longer year.


Why do planets orbit the sun longer than other planets do?

Planets that are farther from the sun have longer orbital periods due to the influence of gravity. The gravitational force between the sun and a planet decreases with distance, so planets farther out experience weaker gravitational pulls, resulting in slower orbital speeds. This explains why outer planets like Neptune have longer orbital periods compared to inner planets like Mercury.


Is it true that the farther away from Earth a galaxy is the slower it is moving?

incorrect. The farther away from earth a galaxy is, the faster it is moving.


What planet moves around sun the slowest?

Neptune would move the slowest. The orbit speed is related to the distant the planets are to the sun. Farther the planet, slower the pace. Remember, Pluto is no longer a planet.


Why does the position of the planet from the sun affect the amount of time it takes for it to revolve around the sun?

The strength of the sun's gravitational field falls off as the square of the distance from the sun. The speed you need to stay in orbit is proportional to the force of attraction. Thus the farther out a planet is, the slower it needs to go to stay in orbit. Note: Mars is only 40% farther from the sun than we are, but it takes 2 whole years to go around the sun once. Its orbit is longer AND its velocity is lower.


Why do planets further from the sun take longer to orbit?

Planets further from the sun have larger orbits, which means they have to travel a greater distance in their orbit. Since they are farther away, the gravitational force from the sun is weaker, causing them to move slower in their orbit. This combination of a greater distance to travel and slower speed results in longer orbital periods for these planets.
