` = "Orbital Velocity of the Earth"`

29784.7357

The **Orbital Velocity of the Earth** is approximately 29,784.7357 m/s m/s.

The Earth travels in a near circular orbit around the Sun. This means that the distance the Earth travels in one year is the circumference of a circle with a radius of one astronomical unit (au).

Velocity is computed as distance divide by time, in this case:

r = 1 astronomical unit

c = 2⋅π⋅r

v = c / (1 sidereal year)

convert v to meters per second

The formula to compute the Orbital Velocity of the Earth is:

v = ( 2⋅π⋅r) / sr

where:

- v = Orbital Velocity of the Earth
- r = mean radius of the Earth from the Sun (aka, 1 astronomical unit)
- sr = sidereal year
