Milky Way

The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Galaxia Kyklos), sometimes referred to simply as "the Galaxy", is a barred spiral galaxy which forms part of the Local Group. Although the Milky Way is but one of millions of galaxies in the universe, the Galaxy has special significance to humanity as it is the home of the solar system, which is located near the Orion Arm. Democritus (460 BC - 370 BC) was the first known person to claim that Milky Way consists of distant stars.

The Milky Way is orbited by a number of dwarf galaxies in the Local Group. The largest of these is the Large Magellanic Cloud with a diameter of 20,000 light years. The smallest, Carina Dwarf, Draco Dwarf, and Leo II Dwarf are only 500 light years in diameter. The other dwarfs orbiting our galaxy are the Small Magellanic Cloud; Canis Major Dwarf, the closest; Sagittarius Dwarf Elliptical Galaxy, previously thought to be the closest; Ursa Minor Dwarf; Sculptor Dwarf, Sextans Dwarf, Fornax Dwarf, and Leo I Dwarf.
