Venus is not Earth’s closest neighbor

physicstoday.scitation.org
  • There is a new method for capturing average distance between planets - the Point-Circle Method (PCM).
  • It led to the discovery of the Whirly-Dirly Corollary: the average distance between two bodies (with coplanar, concentric, circular orbits) decreases as the radius of the inner orbit decreases.
  • The corollary proves that science popularizers have been wrong for years - Mercury, not Venus, is the closest planet to Earth.
  • A 10,000 year-long simulation of the solar system showed that PCM is much more accurate than previously used methods.
