Just as the regression of the nodes of the lunar orbit is connected with the periodicity in the eclipse phenomenon, the advance of perigee is connected with the periodicity in the fluctuations of Moon's synodic period. From the data for 495 synodic months it is found that the gross ...
Full supermoons occur when the orbit of the moon is at perigee - the closest point to Earth in its orbit, which makes the Moon appear bigger and brighter in the night sky. FromBBC A supermoon occurs when the full Moon coincides with when the moon is at its closest point to earth in...
from Late Greekperegeion, used by Ptolemy as a noun, properly neuter of adjectiveperigeios"near the earth," fromperi ges, fromperi"near" (seeperi-) +ges, genitive ofgē"earth" (seeGaia). Now only of the moon, formerly used also for the corresponding point in the orbit of any celesti...
7. The probe entered the earth-moon transfer orbit as scheduled, with a perigee of 200 kilometers and apogee of 380,000 kilometers. 1. 当满月出现在其绕地球轨道最近的一个点,即近地点时,这种现象被通俗地称为"超级月亮"。 2. 月球的距离在其轨...
The Moon's actual distances at apogee and perigee can vary by several percent due to the gravitaional perturbations of the Sun on the Moon's eccentric orbit. Over the 5000-year period from -1999 to 3000 (2000 BCE to 3000 CE), the distance of the Moon's perigee varies from 356,355 ...
The Moon's orbit around Earth is elliptical. The point of the orbit closest to Earth is called perigee, while the point farthest from Earth is known as apogee. The difference between apogee and perigee. timeanddate.com Your Moon guide for February 2025 Elliptical Orbit The Moon's orbit arou...
in astronomy, a value—orbital element—that determines the orientation of the orbit of a celestial body (the moon, artificial earth satellite, planet, comet, and so on) in the plane of the orbit; it is the angle between the nodal line and the direction of the perigee (perihelion) (see...
1. An anomalistic month refers to successive returns to perigee, a period of 27. 55455 days. 一个近点月指的是返回到近地点相继的时间,为27。55455天。 2. The rocket which was designed to take photographs of the moon was launched as the moon approached its perigee. 火箭的目的是拍摄月球...
Moon at Perigee and Apogee: 2001 to 2100 Greenwich Mean Time Introduction The Moon revolves around Earth in an elliptical orbit with a mean eccentricity of 0.0549. As a result, the Moon's distance from Earth (center-to-center) varies with mean values of 363,396 km at perigee (closest) ...
