A slow gyration of the earth's rotational axis around the pole of the ecliptic, caused by the gravitational pull of the sun, moon, and other planets on the earth's equatorial bulge.

What is precession of the perihelion?
The smaller gravitational forces due to the other planets cause the major axis to slowly rotate about the Sun, shifting the line from the Sun to the perihelion through an angle each orbit. This shift is referred to as the precession of the perihelion.
What perihelion means?
the point nearest to the sun Definition of perihelion : the point nearest to the sun in the path of an orbiting celestial body (such as a planet) — compare aphelion. Other Words from perihelion Example Sentences Learn More About perihelion.
What is the definition of the term precession?
Definition of precession : a comparatively slow gyration of the rotation axis of a spinning body about another line intersecting it so as to describe a cone.
What is perihelion and when does it occur?
In 2022, Earth was at perihelion on January 4 at 1:52 A.M. Eastern Time and will be at aphelion on July 4 at 3:10 A.M. Eastern Time. This year, Earth will be 91,406,842 miles away from the Sun at perihelion and 94,509,598 miles away from the Sun at aphelion.
What is the perihelion of Venus?

What causes orbital precession?
Precession – As Earth rotates, it wobbles slightly upon its axis, like a slightly off-center spinning toy top. This wobble is due to tidal forces caused by the gravitational influences of the Sun and Moon that cause Earth to bulge at the equator, affecting its rotation.
What is meant by perihelion and aphelion?
The Earth is closest to the Sun, or at the perihelion, about two weeks after the December solstice, when it is winter in the Northern Hemisphere. Conversely, the Earth is farthest away from the Sun, at the aphelion point, two weeks after the June solstice, when the Northern Hemisphere is enjoying warm summer months.
What is the perihelion Brainly?
The term 'Perihelion' is Earth's closest position to the sun. Any orbit of a planet, comet, and asteroid has a 'Perihelion' and 'Aphelion,' which is the largest distance of the orbit from the sun. At 'Perihelion' earth's center is approximately km away from the sun.
What is precession with example?
An example of precession is the motion of the Earth's polar axis around the normal to the plane of the ecliptic; this is the precession of the equinoxes. A fast-spinning top, with nonvertical axis, which precesses slowly around the vertical direction, is another example.
