Planets with elliptical orbits are affected by the difference in the strength of the Sun's gravity as they move closer to, or farther away from, the Sun. The only other major effect on planets are the gravity of other planets, notably Jupiter and Neptune.
Except for Mars, Ceres, Pluto, and trans-Neptunian planets, the effect is extremely small -- it has resulted in stable orbital resonances between several small outer planets and the planet Neptune.

Why do planets differ in their orbital speed?
Because according to Kepler's laws the orbital speed of a planet is proportional to the square root of the reciprocal of the distance: v = d-½.
Do planets revolve around the sun at the same speed?
No, planets do not revolve around the sun at the same speed. Their orbital speeds depend on their distance from the sun - planets closer to the sun have shorter orbital periods and faster speeds, while those further away have longer orbital periods and slower speeds.
The orbital speed of Venus' and Neptune?
The orbital speed of Venus is around 35.0 km/s while the orbital speed of Neptune is approximately 5.4 km/s. Venus orbits much closer to the Sun than Neptune, leading to its higher orbital speed.
Which planets are closest in orbital speed?
The orbital speeds are higher when closer to the sun, but slower and more similar as you move out. The two that are closest in speed are Uranus and Neptune. Uranus at 6.8352 km/sec and Neptune at 5.4778 km/sec.
Which term refers to the speed at which a planet travel in its orbit?
Orbital velocity refers to the speed at which a planet travels in its orbit.
What planets orbital speed is about 30 kilometers per second?
Mercury has an orbital speed of around 47.87 km/s, which is the closest to 30 km/s among the planets in our solar system.
Why do planets differ in their orbital speed?

This planets orbital speed is about 30 kilometers per second?
there is no answer people sorry!!
Which planets have fastest orbital speed in our solar system?
The ones closest to the Sun.
Do planets revolve around the sun at the same speed?
No, planets do not revolve around the sun at the same speed. Their orbital speeds depend on their distance from the sun - planets closer to the sun have shorter orbital periods and faster speeds, while those further away have longer orbital periods and slower speeds.
Which planets orbital speed is thirty kilometers per second?
The planet with an orbital speed of around 30 kilometers per second is Earth. Its average orbital speed around the Sun is approximately 29.78 kilometers per second.
How does the Earth probably compare in orbital speed to the other planets?
The Earth's orbital speed is relatively high compared to the other planets in our solar system due to its closer proximity to the Sun. Mercury has the fastest orbital speed, followed by Venus and Earth. The gas and ice giants like Jupiter, Saturn, Uranus, and Neptune have much slower orbital speeds due to their larger orbits and distances from the Sun.
What is the orbital speed of planets in miles per second?
It varies: The planets closer to the Sun move faster (Kepler's Third Law). Mercury is fastest; according to Wikipedia, its average orbital speed is 47.87 km/s. Multiply that by 0.6 to get the approximate speed in miles per second.
Which planet moves the most slowly in its orbit?
Of the major planets, Neptune. The speed of planets in their orbits is directly related to their distance from the sun. The farther a planet is from the Sun, the slower its orbital speed.
How are the speeds and orbit times of the planets affected by it?
As it increases, the orbital speed increases, and the period (time to complete an orbit) decreases, which is why Mercury has the shortest year, and Neptune the slowest orbital speed.
The orbital speed of Venus' and Neptune?
The orbital speed of Venus is around 35.0 km/s while the orbital speed of Neptune is approximately 5.4 km/s. Venus orbits much closer to the Sun than Neptune, leading to its higher orbital speed.
Which planets have an orbital speed of less than 18 km per second?
Jupiter, and planets further away from the Sun than Jupiter.
