Astrological Sign
  • Uranus was the son and mate of Gaia, the father of Cronus (Saturn) and of the Cyclopes, and of the Titans (predecessors of the Olympian gods).
  • Careful pronunciation may be necessary to avoid embarrassment. Say: YOOR uh nuhs or yoo RAY nuhs.
  • Pluto was the god of the lower world in Greek mythology whose name meant riches or wealth.

    • A few scientific facts about Uranus:

  • Uranus, the first planet discovered in modern times, was discovered by William Herschel while systematically searching the sky with his telescope on March 13, 1781.
  • It had actually been seen many times before but ignored as simply another star (the earliest recorded sighting was in 1690 when John Flamsteed cataloged it as 34 Tauri).
  • Herschel named it “the Georgium Sidus” (the Georgian Planet) in honor of his patron, the infamous (to Americans) King George III of England; others called it “Herschel”.
  • The name Uranus was first proposed by Johann Elert Bode (1747-1826, German astronomer) in conformity with the other planetary names from classical mythology but it didn't come into common use until 1850.
  • Herschel developed and improved a reflecting telescope and used it to discover the planet Uranus (March 13, 1781) and the moons of Uranus and of Saturn.
  • Uranus is the third of the Gas Giant planets, and the first planet discovered in “modern” times (1781).
  • It is barely visible from the Earth without a telescope, which explains why it was not known as a planet to the ancients, and why it had been observed various times after the telescope had been invented without the observers realizing that it was a planet and not a star.
  • Uranus has five large moons: Miranda, Ariel, Umbriel, Titania, and Oberon.
  • There are ten small satellites and at least nine rings.
  • As with most of the planets, Uranus, too, has a very unique feature.
  • It is the only planet that does not rotate perpendicularly to the ecliptic plane.
  • This is to say that Uranus lies on its side, or tipped over, and its north pole points almost directly toward the sun for a half Uranian year, and its south pole points toward the Sun during the other half.
  • This strange axis tilt produces some extreme seasonal effects.
  • No one knows why Uranus is tilted in this way.
  • Some have speculated that another planet-sized body might have altered the planet’s spin axis, but there is no direct evidence for such an occurrence.
  • Until the Voyager made its probe in space Uranus was known to have five moons.
  • These moons are Miranda, Oberon, Titania, Umbriel and Ariel; but, ten small new moons were discovered within the orbit of Miranda.
  • Uranus moons were named from Shakespeare plays and a poem written by Alexander Pope.
  • All five are approximately 50% denser than water showing that some type of ice is present.
  • This ice is believed to be either methane, ammonia, frozen water, or other types of compounds.
  • All of the moons are dark gray in color which leads scientists to believe they could be covered with carbon soot or graphite.
