Orbital motion in general depends on the mass of the two objects interacting, and the distance between them.

Mathematically, the force of gravitational attraction between two masses is proportional to the product of the two masses, divided by the square of the distance between them, times the gravitational constant (G = 6.67428 x10-11 (m/kg)2):

F = G (m1m2/r2)

"Force equals gravitational constant times the quantity of mass 1 times mass 2 divided by radius squared".

The speed of a planet moving in its orbit is basically a case of circular motion. Planetary orbits are not perfectly circular, but if they were, uniform circular motion and its speed is described mathematically:

V = r (Δθ/Δt)

or

V = rω

Where V is velocity (speed and direction), r is radius (in meters), θ (Greek theta) is the angle swept by the arc, and t is time (in seconds). For the second formula, ω (Greek omega) is angular rate of rotation. Δ (Greek delta) basically means "change".

So you can read the first formula as "velocity equals radius times the quantity of change in angle divided by change in time".

In actual astronomy, since the orbits are not perfect circles, the math is somewhat more complicated. But this is the essence.

How Do Planets Travel Around The Sun?

Planets travel around the Sun in elliptical orbits due to the gravitational pull of the Sun. This gravitational force keeps the planets in their respective paths, causing them to move in a continuous loop around the Sun. The speed at which a planet travels around the Sun depends on its distance from the Sun and the mass of the Sun.


The speed of a planet in its orbit around the Sun depends primarily on the planet's?

The speed of a planet in its orbit around the Sun primarily depends on the planet's distance from the Sun. Planets closer to the Sun move faster in their orbits compared to planets farther away due to the gravitational pull of the Sun. The mass of the planet also plays a minor role in determining its orbital speed.


How are all of the planets kept in orbit around the sun?

all the planets stay in orbit around the sun because of the sun's gravitational pull. The high orbital speed that keeps the planets from falling all the way into the sun and since there is no friction in the vacuum of space , that speed dosen't slow down.


Do the planets travel at the same speed?

No, planets do not all travel at the same speed. The speed at which a planet moves in its orbit around the Sun depends on its distance from the Sun and its mass. Closer planets tend to move faster than those further away.


The planets revolution from the sun?

Each planet in our solar system revolves around the sun in an elliptical orbit. The time it takes for a planet to complete one revolution around the sun is known as its orbital period. This period varies for each planet based on its distance from 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.


Do all the planets travel around the sun at the same speed yes or no?

no they do not


Which of the following planets revolves around the sun with the greatest speed?

Mercury revolves around the sun with the greatest speed among the planets in our solar system. It completes an orbit around the sun in about 88 Earth days, traveling at an average speed of about 107,000 miles per hour.

Why are the planets going in different speed?

The speed that an object travels in its orbit depends on its distance from the sun. That's how gravity works.


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.


Why do the planets differ in their speed of revolution around the sun?

Plantes differ in there speed around the sun because they are all different distances from the sun. The closest planet to the sun in our solar system takes much less time then the farthest because it has much less distance to go.


What is the speed of planets?

The speed of planets will vary as they travel at different speeds. Mercury is the fastest planet while Pluto is the slowest. The speed of the planets is influenced by how close they are to the sun.
