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.
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.
To determine which planet is closest to the Sun based on their orbital periods, we can use Kepler's Third Law, which states that the square of a planet's orbital period is proportional to the cube of its average distance from the Sun. Generally, planets with shorter orbital periods are closer to the Sun. Without the specific values from the table, we cannot identify which planet (A, B, C, or D) is closest, but the one with the shortest orbital period would be the closest to the Sun.
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.
According to http://solarsystem.nasa.gov/planets/, Venus has an orbital velocity of 78,341 mph, and Neptune's is 12,253 mph...
The point when an orbiting object is closest to the central object is called periapsis. For the specific case of planets around the Sun, the term perihelion is used as well.
The ones closest to the Sun.
earth orbital speed is 30 kilometers per second!!
The planet Earth comes very near to that orbital speed at perihelion, its closest distance to the Sun, which occurs on January 3rd or 4th every year.
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.
there is no answer people sorry!!
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 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.
It depends. Which planet is closest to Earth depends on where each of the planets is in its orbit, the planets all have different orbital periods. At any given time the closest planet to Earth may be Mercury, Venus, or Mars. Of all the planets, Venus comes closest.
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.
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.
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.
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.
