Applied to orbits, this effect causes the Laplace-Runge-Lenz [lah- PLASS RUN-jee LENZ] vector to rotate, and types of it include Larmor, De Sitter, and Lense-Thirring.
This effect resulted in erroneous ordering of Flamsteed designations for some stars. Menelaus of Alexandria also made some measurements of this effect among stars, and the Poinsot [pwan SAHT] ellip- soid can be used to visualize this. Applied to orbits, this effect causes the Laplace-Runge-Lenz [lah- PLASS RUN-jee LENZ] vector to rotate, and types of it include Larmor, De Sitter, and Lense-Thirring. Mercury's is observable and was explained by Albert Einstein. On Earth, the torque-induced type applies to gyroscopes, and it can also be torque-free. Identify this effect by which rotating objects have their axis direction changed, often applied to spinning tops.
