Definition

1. Proper noun (Astronomy):

   • The seventh major planet in order of distance from the Sun in our solar system. It is classified as an ice giant, has a distinct blue-green color due to methane in its atmosphere, and is encircled by a system of faint rings composed of ice particles and dust.
   • Example: The Voyager 2 spacecraft provided the first close-up images of Uranus and its moons.

2. Proper noun (Greek Mythology):

   • The primordial deity personifying the sky or heavens. In mythology, he is the son and consort of Gaea (Earth) and the father of the Titans, the Cyclopes, and other early beings.
   • Example: In Hesiod's *Theogony, Uranus was overthrown by his son Cronus.*

Usage Notes

• In both contexts, "Uranus" is always capitalized as it is a proper noun (the name of a specific planet or god).
• In astronomical contexts, it is commonly preceded by the definite article "the" (e.g., "the planet Uranus," "the orbit of Uranus").
• In mythological contexts, it typically stands alone as a name (e.g., "Uranus fathered the Titans").

  • Example: Scientists study Uranian magnetosphere and Uranian weather patterns.
• Mythological Analysis: The name is used in scholarly discussions of cosmogony (the origin of the universe) in Greek myth.
