Only if the corpse had been properly embalmed and entombed in a mastaba, could the dead live again in the Fields of Yalu and accompany the Sun on its daily ride.

This is because the distance between the Earth and the Sun is not fixed ( it varies between AU and AU ) and, when the Earth is closer to the Sun ( perihelion ), the Sun's gravitational field is stronger and the Earth is moving faster along its orbital path.

In Gnostic cosmology, the 7 letters spelling its name represent each of the 7 classic planets — Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn.

Once on course towards the Moon, the crew put the spacecraft into a rotisserie " barbecue " mode in which the craft rotated along its long axis three times per hour to ensure even heat distribution about the spacecraft from the Sun.

Bidwill, with plans already in the works to leave St. Louis, opted instead to sign a long term lease with Arizona State University to use its Sun Devil Stadium as the home of his soon-to-be Arizona-based NFL franchise.

It was discovered in 1725 and later explained by the third Astronomer Royal, James Bradley, who attributed it to the finite speed of light and the motion of Earth in its orbit around the Sun.

For the case of an object that is small compared with the radial distance to its axis of rotation, such as a tin can swinging from a long string or a planet orbiting in a circle around the Sun, the angular momentum can be expressed as its linear momentum,, crossed by its position from the origin, r. Thus, the angular momentum L of a particle with respect to some point of origin is

It is at least 110 times visually more luminous than the Sun, but this underestimates its strength as much of the " light " it gives off is in the infrared ; total ( bolometric ) power output is about 180 times that of the Sun.

It is moving rapidly () relative to the solar system, and is now almost at its closest point to the Sun.

It has a radius of approximately 883 times that of the Sun ; if it were placed in the center of our solar system, its outer surface would lie between the orbits of Mars and Jupiter.

Its visual luminosity is about 10, 000 times that of the Sun, but because the star radiates a considerable part of its energy in the infrared part of the spectrum, the bolometric luminosity equals roughly 65, 000 times that of the Sun.

Altair is a type-A main sequence star with approximately 1. 8 times the mass of the Sun and 11 times its luminosity.

The type of display presented by the comet depends on its composition and how close it comes to the Sun.

Because the volatility of a comet's material decreases as it gets further from the Sun, the comet becomes increasingly difficult to observe as a function of not only distance, but the progressive shrinking and eventual disappearance of its tail and the reflective elements it carries.

Novell provided desktop manager components and scalable systems technologies from UNIX System V. Sun contributed its ToolTalk application interaction framework and a port of its DeskSet productivity tools, including mail and calendar clients, from its OpenWindows environment.

Sun Yat-sen's career was at its lowest point then, with most of his old Revolutionary Alliance comrades refusing to join him in the exiled Chinese Revolutionary Party.

The CIA allegedly wanted to help Sun take control of Taiwan and declare its independence.

One of his most memorable exchanges on HIGNFY occurred when he scathingly joked to fellow guest Piers Morgan that the Daily Mirror was now, thanks to Morgan ( then its editor ), almost as good as The Sun.

In this case, the absolute magnitude is defined as the apparent magnitude that the object would have if it were one astronomical unit ( AU ) from both the Sun and the observer.

In the case of an observer on Earth, the direction of a star's velocity varies during the year as Earth revolves around the Sun ( or strictly speaking, the barycenter of the solar system ), and this in turn causes the apparent position of the star to vary.

* A solar calendar is based on perceived seasonal changes synchronized to the apparent motion of the Sun ; an example is the Persian calendar.

He argued that the apparent retrograde motion of the planets is an illusion caused by Earth's movement around the Sun, which the Copernican model placed at the centre of the Universe.

The ecliptic is the apparent path of the Sun on the celestial sphere as seen from the Earth's center, and also the plane of this path, which is coplanar with the orbit of the Earth around the Sun.

Due to the movement of the Earth around the Earth-Moon barycenter, the apparent path of the Sun wobbles slightly, with a period of about one month ; due to perturbations by the other planets of the Solar System, the Earth-Moon barycenter wobbles slightly around a mean position in a complex fashion.

The ecliptic is actually the apparent path of the Sun throughout the course of a year.

As the Earth takes one year to make a complete revolution around the Sun, the apparent position of the Sun also takes the same length of time to make a complete circuit of the ecliptic.

Periodic motions of the Moon and apparent periodic motions of the Sun ( actually of the Earth in its orbit ) cause short-term small-amplitude periodic oscillations of the axis of the Earth, and hence the celestial equator, known as nutation.

This is because Earth's apparent diameter from the viewpoint of the Moon is nearly 4 times that of the Sun.

More precisely, a full moon occurs when the geocentric apparent ( ecliptic ) longitudes of the Sun and Moon differ by 180 degrees ; the Moon is then in opposition with the Sun .< ref >

The error in the position of the Moon itself is only maybe 0. 5 "/ cy < sup > 2 </ sup >, or ( because the apparent mean angular velocity of the Moon is about 0. 5 "/ s ), 1 s / cy < sup > 2 </ sup > in the time of conjunction with the Sun.

First, the parallax ( the small change in apparent position over the course of a year caused by the Earth moving from one side of its orbit around the Sun to the other ) of stars in close open clusters can be measured, like other individual stars.

To reduce the chances that a faster-moving ( and thus closer ) object be mistaken for the new planet, Tombaugh imaged each region near its opposition point, 180 degrees from the Sun, where the apparent retrograde motion for objects beyond Earth's orbit is at its strongest.

Using a common-view measurement method based on the received signals from radio station WWV, they determined the orbital motion of the Moon about the Earth, from which the apparent motion of the Sun could be inferred, in terms of time as measured by an atomic clock.

The absolute magnitude of the Sun is 4. 8, so, at a distance of, the Sun would have an apparent magnitude: .</ ref >

In both astrology and historical astronomy, the zodiac ( Greek: ζῳδιακός, zōidiakos ) is a circle of twelve 30 ° divisions of celestial longitude that are centered upon the ecliptic: the apparent path of the Sun across the celestial sphere over the course of the year.

A symbolic geometric construction around 15 to 18 degrees wide, it is divided into 12 signs, each of 30 degrees longitude ( making 360 degrees in all ), with the ecliptic, the apparent path of the Sun, as its middle line.

Apparent solar time (' apparent ' is often used in English-language sources, but ' true ' in French astronomical literature ) is based on the solar day, which is the period between one solar noon ( passage of the real Sun across the meridian ) and the next.

As with sources already successfully modeled by X-ray astrophysics, striving to understand the generation of X-rays by the apparent source helps to understand the Sun, the universe as a whole, and how these affect us on Earth.

In his Rudolphine Tables ( 1627 ), Johannes Kepler used a prototype of year zero which he labeled Christi ( Christ ) between years labeled Ante Christum ( Before Christ ) and Post Christum ( After Christ ) on the mean motion tables for the Sun, Moon, Saturn, Jupiter, Mars, Venus and Mercury.

On the Reckoning of Time ( De temporum ratione ) included an introduction to the traditional ancient and medieval view of the cosmos, including an explanation of how the spherical earth influenced the changing length of daylight, of how the seasonal motion of the Sun and Moon influenced the changing appearance of the New Moon at evening twilight, and a quantitative relation between the changes of the Tides at a given place and the daily motion of the moon.

Since the focus of his book was calculation, Bede gave instructions for computing the date of Easter and the related time of the Easter Full Moon, for calculating the motion of the Sun and Moon through the zodiac, and for many other calculations related to the calendar.

The discovery of Ceres led Gauss to his work on a theory of the motion of planetoids disturbed by large planets, eventually published in 1809 as Theoria motus corporum coelestium in sectionibus conicis solem ambientum ( Theory of motion of the celestial bodies moving in conic sections around the Sun ).

Alpha Centauri, one of the closest stars to the Sun, has a high proper motion ; it will be a mere half-degree from Beta Centauri in approximately 4000 years.

The dipole anisotropy and others due to Earth's annual motion relative to the Sun and numerous microwave sources in the galactic plane and elsewhere must be subtracted out to reveal the extremely tiny variations characterizing the fine-scale structure of the CMBR background.

The path of the Sun is not normally noticeable from the Earth's surface because the Earth rotates, carrying the observer through the cycle of sunrise and sunset, obscuring the small motion of the Sun against the background stars.

Ephemeris time was defined in principle by the orbital motion of the Earth around the Sun, ( but its practical implementation was usually achieved in another way, see below ).

Although ephemeris time was defined in principle by the orbital motion of the Earth around the Sun, it was usually measured in practice by the orbital motion of the Moon around the Earth.

These measurements can be considered as secondary realizations ( in a metrological sense ) of the primary definition of ET in terms of the solar motion, after a calibration of the mean motion of the Moon with respect to the mean motion of the Sun.

The fictitious mean sun is the annual average of this nonuniform motion of the true Sun, necessitating the inclusion of mean in Greenwich Mean Time.

He was the first whose quantitative and accurate models for the motion of the Sun and Moon survive.

Having made the assumption that the Sun was at the center of the universe, Copernicus realized that calculating tables of planetary motion ( mathematical charts that describe the movements of planets ) was much easier and more accurate.

Kepler supposed that the motive power ( or motive species ) radiated by the Sun weakens with distance, causing faster or slower motion as planets move closer or farther from it.

Based on measurements of the aphelion and perihelion of the Earth and Mars, he created a formula in which a planet's rate of motion is inversely proportional to its distance from the Sun.
