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.
The orbital speed of Venus' and Neptune?
According to http://solarsystem.nasa.gov/planets/, Venus has an orbital velocity of 78,341 mph, and Neptune's is 12,253 mph...
What keeps the planets from being pulled to the sun's surface by gravity?
The orbital speed of the planets prevent this. The planet's ARE all failing towards the Sun but their horizontal speed means they always miss.
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.
What is the orbital speed of Titan?
average orbital speed of 9.69km/s
What planets orbital speed is about 30 kilometers per second?
earth orbital speed is 30 kilometers per second!!
Which planets orbital speed is thirty kilometers per second?
venus

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.
How does the Earth probably compare in orbital speed to the other planets?
The Earth moves faster than the planets that are farther from the Sun.
The orbital speed of Venus' and Neptune?
According to http://solarsystem.nasa.gov/planets/, Venus has an orbital velocity of 78,341 mph, and Neptune's is 12,253 mph...
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.
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.
Which planets have an orbital speed of less than 18 km per second?
Jupiter, and planets further away from the Sun than Jupiter.
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.
What keeps the planets from being pulled to the sun surface by gravity?
The orbital speed of the planets prevent this. The planet's ARE all failing towards the Sun but their horizontal speed means they always miss.
