Orders of magnitude (angular frequency) (aka angular speed or angular velocity or angular rate).
Value (radian per second [rad/s]) | Item | |
---|---|---|
8.849×10 | Sun’s orbit around the center of the Milky Way, assuming an orbital period (galactic year) of 225 million years.[1] | |
8.03×10 | Pluto’s orbit, orbital period 247.94 Earth years (average angular speed; actual angular speed varies because Pluto's orbit is eccentric). See Plutino. | |
1.991×10 | Earth's orbit around the Sun (1 year). | |
2.66×10 | Moon’s orbit around Earth, assuming a period of 27.32 days (a sidereal month, i.e. orbital period with respect to deep space). See Orbit of the Moon. | |
7.272×10 | Earth's rotation (1 day). | |
1.745×10 | Something that rotates once per hour: 2π/3600 rad/s. | |
0.1047 | Something that rotates once per minute: 2π/60 rad/s. | |
6.283 | 1 hertz: 2π rad/s. | |
4500 | Rotation of PSR J1748−2446ad, the fastest-spinning known pulsar: 716 hertz.[2] |
