The name Varuna may be Indo-European, identifiable, some believe, with the Greek ofpavos (Uranus), and ultimately referable to a root var, " to cover," Varuna thus meaning "the Encompasser."
This is true not only of the major planets Mercury, Venus, the Earth, Mars, Jupiter, Saturn, Uranus and Neptune; it is also true of the host of more than five hundred minor planets.
Discarding those of Uranus, in which the orbits of the satellites are highly inclined to the ecliptic, and in which manifestly some exceptional influences have been at work, we find that the satellites revolve around the primaries also in the same direction (Exceptions are Saturn ix.
Uranus (Astronomy) >>
The outer group of major planets comprises: Jupiter, 24,24, with seven satellites; Saturn, T?, with ten satellites; Uranus, a or 1, with four satellites; Neptune, with one satellite.
Exceptions occur in the case of the satellites of Uranus, which are nearly perpendicular to the plane of the orbit.
The system of Algol, according to this view, is triple; it includes a large, obscure primary, round which the eclipsing pair revolves in an orbit somewhat smaller than that of Uranus, very slightly elliptical, and inclined 20° to the line of sight, the periodic time being 118 years.
1 33, 337-37 o) the son of Uranus and Gaea, the husband of Tethys, father of 3000 streams and 4000 ocean nymphs.
Here Delambre observed and computed almost uninterruptedly, and in 17 9 0 obtained for his Tables of Uranus the prize offered by the academy of sciences, of which body he was elected a member two years later.
His researches into the perturbations of Uranus and Neptune (Proc. Amer.
URANUS (Heaven), in Greek mythology, the husband of Gaea (Earth), and father of Cronus (Saturn) and other deities.
Uranus and other Greek gods anterior to Zeus were probably deities worshipped by earlier barbarous inhabitants of the land.
He was the son of Poseidon (or Uranus) and Gaea.
Among his contributions to astronomy may be noted his eleven zonecatalogues of 34,674 stars, his measurements, in 1836-1837, of nebulae and clusters, and his determination of the mass of Uranus from observations of its satellites (Mena.
The discovery of Neptune (1846), due to the influence of this planet on the motion of Uranus, may be mentioned as its most dramatic achievement.
In Hesiod (Theogony, 264) they are the three sons of Uranus and Gaea - Brontes, Steropes and Arges, - storm-gods belonging to the family of the Titans, who furnished Zeus with thunder and lightning out of gratitude for his having released them from Tartarus.
Equatorial at the United States Naval Observatory, Newcomb devoted it almost exclusively for the first two years to observations of the satellites of Uranus and Neptune, being of opinion that it was better to do one thing well than many things indifferently.
The results of these skilfully conducted observations were published in a memoir on The Uranian and Neptunian Systems. 3 From this research it appears that the orbits of all four satellites of Uranus are sensibly circular, and although no special search was made, he concludes that none of Sir William Herschel's supposed outer satellites can have any real existence.
From the motion of the satellites he finds that the mass of Uranus is - T - A o o th of that of the sun, while for the planet Neptune he finds a mass equal to 19 Toth of the sun, agreeing with the value previously found by him from the perturbations of Uranus within o th of its amount.
185) they were the daughters of Earth, and sprang from the blood of the mutilated Uranus; in Aeschylus (Eum.
Thus, in the Hesiodic account of her birth, she is represented as sprung from the foam which gathered round the mutilated member of Uranus, and her name has been explained by reference to this.
According to Plato (Symposium, 180), there are two Aphrodites, " the elder, having no mother, who is called the heavenly Aphrodite - she is the daughter of Uranus; the younger, who is the daughter of Zeus and Dione - her we call common."
RHEA, a goddess of the Greeks known in mythology as the daughter of Uranus and Gaia, the sister and consort of Kronos, and the mother of Zeus.
While still an undergraduate he happened to read of certain unexplained irregularities in the motion of the planet Uranus, and determined to investigate them as soon as possible, with a view to ascertaining whether they might not be due to the action of a remote undiscovered planet.
Meanwhile, Leverrier, on the 10th of November 1845, presented to the French Academy a memoir on Uranus, showing that the existing theory failed to account for its motion.
As the indisputable facts became known, the world recognized that the two astronomers had independently solved the problem of Uranus, and ascribed to each equal glory.
