The evidence was compiled by W de Sitter ( 1927 ) who wrote " If we accept this hypothesis, then the ' astronomical time ', given by the earth's rotation, and used in all practical astronomical computations, differs from the ' uniform ' or ' Newtonian ' time, which is defined as the independent variable of the equations of celestial mechanics ".

In particular, astral magic, involving invoking and praising the powers of celestial bodies into talismans and amulets was introduced to significant effect.

As a result of improvements Galileo Galilei made to the telescope, with a magnifying capability of 20 ×, he was able to see celestial bodies more distinctly than was ever possible before.

More importantly, the discovery of celestial bodies orbiting something other than the Earth dealt a blow to the then-accepted Ptolemaic world system, which held that the Earth was at the center of the universe and all other celestial bodies revolved around it.

In his view, the Milky Way was celestial.

Its first depiction in a celestial atlas was in Johann Bayer's Uranometria of 1603.

Celestial objects were described as moving in circles, because perfect circular motion was considered an innate property of objects that existed in the uncorrupted realm of the celestial spheres.

Shen's contemporary Su Song ( 1020 – 1101 ) was also a polymath and astronomer responsible for the creation of celestial atlas of star maps, as well for writing a pharmaceutical treatise with related subjects of botany, zoology, mineralogy, and metallurgy.

In a more general usage in celestial mechanics, the expression ' tidal force ' can refer to a situation in which a body or material ( for example, tidal water, or the Moon ) is mainly under the gravitational influence of a second body ( for example, the Earth ), but is also perturbed by the gravitational effects of a third body ( for example, by the Moon in the case of tidal water, or by the Sun in the case of the Moon ).

The term " zodiac " may also refer to the region of the celestial sphere encompassing the paths of the planets corresponding to the band of about eight arc degrees above and below the ecliptic.

A celestial sphere can also refer to a physical model of the celestial sphere or celestial globe.

They also refer to plural marriage generically as " the Principle ", " celestial marriage ", " the New and Everlasting Covenant ", or " the Priesthood Work ".

Nevertheless, it is correct and can be demonstrated that " celestial marriage " was often used to refer to plural marriage.

" Swedenborg does not use " celestial marriage " to refer to the marriage of husband and wife, although he says that the marriage of husband and wife has its origin in the heavenly or celestial marriage of goodness and truth.

Qutb can refer to celestial movements and used as an astronomical term or a spiritual symbol.

By convention, sunrise and sunset refer to times at which the Sun ’ s upper limb appears on or disappears from the horizon ; the standard value for the Sun ’ s true altitude is − 50 ′: − 34 ′ for the refraction and − 16 ′ for the Sun ’ s semidiameter ( the altitude of a celestial body is normally given for the centre of the body ’ s disc ).

The cats also use ways of measuring time and distance more related to the natural world: sunhigh and moonhigh refer to the positions of celestial bodies as an indication of time.

) For example, " the morning star " and " the evening star " both refer to the object Venus, but they present it to us in different ways: the former as the brightest celestial body visible in the morning, the latter as the brightest celestial body visible in the evening.
