What is Orbital Speed Calculator?

The Orbital Speed Calculator is a tool that calculates the speed of an object in orbit around a central body, such as a planet or a satellite. The calculator uses the formula for orbital speed, which takes into account the gravitational force between two objects and the distance between them.

Formula:

The formula for calculating the orbital speed is:

OrbitalSpeed=SQRT(G∗m/r)

Where:

  • G is the gravitational constant (6.67430e-11 m^3/(kg*s^2))
  • m is the mass of the central body (in kilograms)
  • r is the distance from the center of the central body to the object in orbit (in meters)

Calculation:

To use the Orbital Speed Calculator, you need to enter the value of the orbital radius in meters in the input field provided. Once you click the calculate button, the calculator will use the formula to calculate the orbital speed in m/s. The result will be displayed in the output field.

Example:

Suppose we want to calculate the orbital speed of a satellite orbiting the Earth at a distance of 400 km from the Earth’s center. The mass of the Earth is approximately 5.972e24 kg. Using the formula, we get:

OrbitalSpeed=SQRT(G∗m/r) OrbitalSpeed=SQRT(6.67430e-11*5.972e24/(400000+6371000)) OrbitalSpeed=7668.62 m/s

Therefore, the orbital speed of the satellite is approximately 7668.62 m/s.

FAQs:
