Why Do Constellations Change?

Earth orbits the sun over one year. Different parts of the sky face away from the sun at different times, making different constellations visible each season.

  • Winter: Orion is high in the sky
  • Spring: Leo rises in the east
  • Summer: Cygnus and Scorpius shine
  • Fall: Pegasus and Cassiopeia are prominent

Year-Round Constellations

Some constellations near the North Pole are visible all year from the Northern Hemisphere because they never set below the horizon.

  • Big Dipper (Ursa Major)
  • Cassiopeia
  • Polaris (North Star) marks true north
