Common Misconceptions

  • Pluto is a planet: Pluto was reclassified as a dwarf planet in 2006 due to its inability to clear its orbital neighborhood.
  • The Solar System is static: Planetary orbits and positions change over time due to gravitational interactions.
  • All planets have similar environments: Each planet has unique atmospheric, geological, and magnetic properties.
  • Asteroids are only found in the asteroid belt: Near-Earth objects (NEOs) frequently cross Earth’s orbit.
  • Solar System ends at Pluto: The Solar System extends far beyond Pluto, including the Kuiper Belt and Oort Cloud.
  • Solar storms only affect space: Powerful solar events can disrupt terrestrial technologies and power grids.
