Question

What is the orbital velocity of the planet?

Answer 1

Orbital velocity or average velocity :

1. The speed at which a body revolves around another is known as orbital velocity.
2. The following formula is used to compute the orbital velocity:$=\sqrt{\frac{GM}{R}}$ Where $G$ is the gravitational constant with the value$6.673\times {10}^{-11}{\mathrm{Nm}}^2/{\mathrm{kg}}^2$ where $\mathrm{M}$ is the mass of the body at the center and $R$ is the radius of the orbit.
3. In the solar system, Mercury has the fastest orbital speed and Neptune has the lowest orbital speed.
4. The orbital velocity of the earth is $29.78\mathrm{km}/\mathrm{s}$
