The Twin Sister Planets Venus and Earth: Why are They So Different?

  • A comprehensive model for the evolution the planet Earth and Venus over Geologic Time
  • Offers a new approach to the intact capture model
  • Contains proposed tests of the models presented
  • Has many significant implications for the argument that habitable planets may be fairly rare in a large region of space

About this book

The Twin Sister Planets Venus and Earth explains how it came to be that Venus and Earth, while very similar in chemical composition, zonation, size and heliocentric distance from the Sun, are very different in surface environmental conditions. It is argued here that these differences can be accounted for by planetoid capture processes and the subsequent evolution of the planet-satellite system. Venus captured a one-half moon-mass planetoid early in its history in the retrograde direction and underwent its "fatal attraction scenario" with its satellite (Adonis). Earth, on the other hand, captured a moon-mass planetoid (Luna) early in its history in prograde orbit and underwent a benign estrangement scenario with its captured satellite.
