## Lense-Thirring Frame Dragging
A rotating massive body drags the surrounding spacetime, causing gyroscopes to precess.
### Formula
**Omega_LT = 2GJ / (c^2 r^3)**
- *G* = gravitational constant
- *J* = angular momentum of the central body
- *c* = speed of light
- *r* = orbital radius
This effect was confirmed by Gravity Probe B to within about 19% of the predicted value for Earth.

Satellite at 630 km altitude around Earth (r = 7e6 m, J_Earth = 7.07e33 kg m2/s).
- Omega = 2 * 6.674e-11 * 7.07e33 / (8.988e16 * 3.43e20)
- = 9.437e23 / 3.083e37
- = 3.061e-14 rad/s
- In mas/yr: about 39 mas/yr
