Mars takes longer to make one orbit of the sun. Its slower, and it also has further to go. Planets orbiting speeds get slower the further you go out.
Most asteroids orbit around stars and move faster than them.
That is because the Moon's orbit is not exactly circular. Any orbit of one object around another is an ellipse; in this case, when the Moon is closer to Earth, it moves faster; when it is farther away, it moves slower.
Neptune is the slowest and mercury is the fastest
Gravity keeps satellites in orbit. The closer you are to the Earth, the faster you have to go to maintain your orbit. At low Earth orbit, the altitude of the Space Station, you make an orbit every 90 minutes. At the Moon's distance you need over 27 days to go around the Earth. In-between there is an altitude which matches the rate of the Earth's rotation. Many satellites orbit at this altitude.
As discovered by Johannes Kepler, the closer a planet is to the sun, the faster it's orbit becomes. As you might expect Mercury completes it's orbit (year) in the fastest time, and each outer planet does so progressively slower.
Slower or faster than what? - When the Earth is nearer the Sun (periapsis), it moves faster than when it is farther away from the Sun (apapsis).
Most asteroids orbit around stars and move faster than them.
The Earth's orbit is an ellipse with the Sun at one focus of the ellipse. But it isn't very eccentric; the orbit is almost circular, but not quite.If the Earth's orbit was circular, it would travel at about 67,000 miles per hour. At perihelion (in January) the Earth is moving a little faster than that, while at aphelion (in July) it is moving just a little slower.

The curved path is called the orbit. Each planet has its own orbit. Some are faster and some are slower. They are caused by the gravity of the planet and the sun
Since the gravitational effect of the Sun decreases with distance from it, the planets farther from the Sun do not have to move as rapidly to remain in orbit. (In fact, the speed is what establishes the orbit, not the other way around.) So the outer planets, in addition to having much farther to travel in their orbits, are also moving more slowly. This combination means that outer planets take very much longer to orbit the Sun than do the inner planets such as Earth. By comparison, the length of time it takes (in Earth years) for each of the outer planets to make one complete revolution around the Sun: Jupiter - 11.9 Earth years Saturn - 29.5 Earth years Uranus - 84 Earth years Neptune - 165 Earth years

The average speed of the earth in orbit is around 30 km/sec or 108,000 km/h. The planet moves faster when it's closer to the sun and slower when it's further away, sweeping out equal areas in equal time.

When there is slow rotation and orbit around the sun , day and night in earth is affected not only that but due to slow rotation seasons in earth also changes slowly .As there is sloe season change in directly affects on agriculture on earth.
