"This book explains how it came to be that Venus and Earth,℗ℓwhile 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℗ℓaccounted for℗ℓby 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 ℓ́ℓfatal attraction scenarioℓ́ℓ with its satellite (Adonis). ℗ℓEarth, 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."@en . . . . . . . . . . . . . .
