Earth is located in the Milky Way galaxy, which is a spiral galaxy that contains billions of stars, including our sun. Specifically, Earth is located in one of the spiral arms of the Milky Way, called the Orion Arm or Orion-Cygnus Arm. The Milky Way is vast, measuring about 100,000 light-years in diameter, and Earth is situated approximately 27,000 light-years from the center of the galaxy. Despite being just one of billions of planets in the Milky Way, Earth holds a special significance for us as it is our home.
