WebThe present-day value of the longitude of the perihelion is ϖ = 102.04°, which gives a climatic precession of e sin ϖ = 0.01636. In this situation the Earth is at the closest distance to the Sun in early January (Berger and Loutre, 1994).Therefore the mean solar irradiance received during the southern summer in the Southern Hemisphere is larger than the mean … In astronomy, precession refers to any of several gravity-induced, slow and continuous changes in an astronomical body's rotational axis or orbital path. Precession of the equinoxes, perihelion precession, changes in the tilt of Earth's axis to its orbit, and the eccentricity of its orbit over tens of thousands … See more Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. … See more • Larmor precession • Nutation • Polar motion • Precession (mechanical) See more • Media related to Precession at Wikimedia Commons • Explanation and derivation of formula for precession of a top See more Torque-free precession implies that no external moment (torque) is applied to the body. In torque-free precession, the angular momentum is a constant, but the angular velocity vector … See more Torque-induced precession (gyroscopic precession) is the phenomenon in which the axis of a spinning object (e.g., a gyroscope) describes a cone in space when an external torque is applied to it. The phenomenon is commonly seen in a spinning toy top, … See more

WebJul 21, 2005 · The precession of the perihelion of Mercury’s orbit is calculated using the Laplace–Runge–Lenz vector. An approximate calculation that assumes the orbits of the perturbing planets are circular and coplanar with Mercury’s orbit is within 4.4% of the correct value.
