In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis. In the absence...

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 Moon's axial precession is westwards - whereas Apsidal precession is in the same direction as the rotation (meaning apsidal precession is eastward)...

an axial tilt of about 23.44°. This value remains about the same relative to a stationary orbital plane throughout the cycles of axial precession. But...

In the 1920s, he hypothesized that variations in eccentricity, axial tilt, and precession combined to result in cyclical variations in the intra-annual...

plane. Nodal precession, where non-spherical objects cause orbiting objects to change their orbits. Not to be confused with: Axial precession, where the...

every 72 years from the perspective of the Earth due to the Earth's axial precession, tropical systems consider 0 degrees of Aries as always coinciding...

around the Sun. Minor variation in the direction of the axis, known as axial precession, takes place over the course of 26,000 years. As a result, over the...

Astronomical precession Axial precession or precession of the equinoxes, the precession of the Earth's axis of rotation Apsidal precession, the rotation of the...

intersection, tracing a tiny circle in the sky each sidereal day. Due to the axial precession of Earth, true north rotates in an arc with respect to the stars that...

without any awareness of axial precession. Hipparchus (c. 120 BC) is the first Greek credited with discovering axial precession roughly two hundred years after...

product of the Earth's slow precessional rotation and lasts for 2,160 years, on average (one 25,920-year period of precession, or Great Year, divided by...

eastward by 360°. The Moon's apsidal precession is distinct from the nodal precession of its orbital plane and axial precession of the moon itself. The mean inclination...

or two, for several reasons explained below. Because of the Earth's axial precession, this year is about 20 minutes shorter than the sidereal year. The...

In celestial mechanics, apsidal precession (or apsidal advance) is the precession (gradual rotation) of the line connecting the apsides (line of apsides)...

model for the body. Axial precession, or "precession of the equinoxes" for Earth Apsidal precession, another kind of orbital precession (the change in the...

the right. Minor variation in the direction of the axis, known as axial precession, takes place over the course of 26,000 years, and therefore is not...

in relation to the sun. Star years measured in this way vary due to axial precession, the movement of the Earth's axis in relation to the sun. The length...

Earth's axial tilt Jah Wobble (born 1958), British musician Milankovitch wobble, long-term change in the Earth's axial tilt, axial precession and orbital...

Every year sidereal and tropical equinoxes slide by 50 seconds due to axial precession, giving birth to Ayanamsha and causing Makara Sankranti to slide further...

J2000.0 (365.242 190 402 ephemeris days). At present, the rate of axial precession corresponds to a period of 25,772 years, so sidereal year is longer...

Sun on the northern solstice (June 21). During the first century AD, axial precession shifted it into Gemini. In 1990, the location of the Sun at the northern...
