THE TWIN SISTER PLANETS VENUS AND EARTH - ROBER...

This book 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.
