A Prograde Gravitational Capture Model for a Sizeable Volcanoid Planetoid (or Asteroid) for Mars
In this chapter we explore the consequences of capturing a 0.1 moon-mass (~0.01 mars-mass) planetoid from a mars-like heliocentric orbit into a stable prograde orbit of large major axis and high eccentricity. One of the major paradoxes of the gravitationa

Pictogram illustrating a Mars-like planet in a prograde (counter clockwise) Mars-like heliocentric orbit with a moderately large satellite, about 1/100 the mass of Mars, in a prograde orbit around the Mars-like planet rotating in the prograde direction. The general theme of the book is that regular tidal action (i.e., both rock and ocean tides) operating over geologic time (in this case marologic time) keeps a planet “alive” by aiding the processes that cycle and recycle planetary resources. Note also that a satellite helps to stabilize the obliquity (tilt angle) of a planet over multithousand-year cycles. The obliquity for this illustration is 30 degrees. The initial obliquity could be more or less than this value but the main point is that it is stable over long periods of time. This stability of obliquity results in a seasonal cycle that is very consistent from year to year, decade to decade, and century to century. This stability of the seasonal cycle, along with other factors such as the presence of liquid water on the surface of a planet, is very conducive to the origin and evolution of life
