CHE SIGNIFICA MEAN SUN IN INGLESE
Tempo solare
L'ora solare è un calcolo del passaggio del tempo sulla base della posizione del Sole nel cielo. L'unità fondamentale del tempo solare è la giornata. Due tipi di tempo solare sono il tempo solare apparente e il tempo solare medio.
definizione di mean sun nel dizionario inglese
La definizione di sole medio nel dizionario è un sole immaginario che si muove lungo l'equatore celeste a una velocità costante e completa il suo corso annuale nello stesso tempo in cui il sole impiega a muoversi intorno all'eclittica a velocità variabile. È usato nella misurazione del tempo solare medio.

Orbital Motion, Fourth Edition
(i) A fictitious body called the dynamical mean sun is introduced which starts off
from perigee with the Sun, moves with the mean angular velocity (mean motion)
of the Sun and returns to perigee at the same time as the Sun. It also moves in

Mean Solar Time Since our modern clocks and chronometers cannot record the
variable apparent solar time, a fictitious sun called the mean sun is imagined to

An Elementary Treatise on Plane and Spherical Trigonometry: ...
To avoid the irregularity of time arising from the want of uniformity of the sun's
motion, a fictitious sun, called a mean sun, is supposed to move uniformly in the
ecliptic, at such a rate as to return to the perigee at the same time with the true
sun.
Since the sun has a movement relative to the celestial sphere and since it is not
uniform, it becomes necessary to assume a mean sun, a point travelling the
celestial equator at a uniform rate so as to make solar days of uniform length.
