  There is no real logic behind Swift's choice of two moons for Mars – although it has been suggested that since Venus has no moons, Earth has one, then logically Mars should have two. But by this same logic we are presumably led to the conclusion that Mercury should have minus-one moons! Clearly, the number chosen by Swift was immaterial to his narrative, and it just happened to be the right number with respect to reality.
  Just for fun, however, let us continue the theme set in motion by Swift, and upon the basis that even a stopped clock (a mechanical analog one, that is) tells the correct time twice a day, let us briefly review, for future posterity, how many planets and moons have been invoked within a (small) sample of science fiction works for the stars of α Centauri.
  The number of Centaurian planets and associated moons as described in a small sample of science-fiction works, movies and video-games published between 1932 and 2009. HZ indicates that the planet was deemed to be in a habitable region of the star system. (i) Number not specified. (ii) Brackett appears to be unaware that α Centauri is not a single star. (iv) One of the planets is an Earth-sized waterworld developed and maintained through terraforming. (v) Several of the moons have atmospheres and liquid water upon their surfaces. The two outermost moons have retrograde orbits suggestive of being capture asteroids/Kuiper Belt like objects. The second Jovian planet has 2 planetoid companions at the L4 and L5 Lagrange points
  Somewhat surprisingly the number and types of planets suggested as possible companions to Proxima Centauri has varied more than those invoked for α Cen A or B – indeed, for Proxima the number of planets has varied between zero and eight. Again, surprisingly, for all of the contemporary astronomical facts and snippets that Mader drops, Jules Verne-like, into his Distant Worlds narrative, no mention of Proxima is even made.
  Other imagined planets set in motion around Proxima are described as being dwarf planets or asteroids, like Ceres in our own planetary system; some of the planets are deemed to be habitable, and some have at least one moon.

conversations.value: The evolution of α Cen A and B will be contrasted against that of the Sun in the section below. In the meantime, however, the catastrophic influences of an aging Sun on the rest of the Solar System and specifically its habitability zone will be considered.
  The evolutionary changes that will take place in the Sun will have three direct effects on the rest of the Solar System. First, the Sun's increasing luminosity will drive planetary temperatures higher; second its radius will expand to beyond the orbits presently occupied by the inner most terrestrial planets; and third, its loss of mass will cause all planetary orbits to change. All three of these effects will combine to destroy any and all of the life-forms that presently exist within the Solar System's habitability zone.
  In deriving Eq. 3.2 it is assumed that the planet has a sufficiently rapid period of rotation that its entire surface is uniformly heated and radiates energy back into space. In the slower rotation case, where only one hemisphere is heated and radiates energy back into space, the 278 numerical term is multiplied by a factor of 2¼ ≈ 1.2. Additionally, it is worth noting that the temperature of a planet does not depend on its physical size but only on its orbital distance from the Sun, along with its albedo and emissivity characteristics. For Earth, typical albedo and emissivity average values are A = 0.3, and ε = 0.6; for the Moon they are typically taken as A = 0.1 and ε = 0.9.
  Substituting values appropriate to Earth at the present time, with L = 1 L⊙, Eq. 3.2 indicates that T(Earth) = 288 K, which is indeed the characteristic global average temperature for Earth. The result just derived is partly a cheat in that Eq. 3.2, through the introduction of the albedo and emissivity terms, has been adjusted to include a greenhouse heating effect. This effect relates to the manner in which the atmosphere modifies the surface re-radiation process. The solar energy that initially warms the surface of Earth penetrates the atmosphere at wavelengths corresponding to visible light.

  Technically six parameters are required to determine a star's future trajectory through space: these are its galactic (x, y, z) position coordinates and its galactic (Vx, Vy, Vz) velocity components. Once these parameters are specified at one specific epoch then, adopting some specific model for the gravitational potential of the Milky Way galaxy (technically including the central bulge, the disk, as well as the halo), the equations of motion can be numerically integrated forwards (or backwards) in time. An example of such calculations is presented by Juan Jiménez-Torres et al., in the research article "Effect of different stellar galactic environments on stellar discs – I: The solar neighborhood and the birth cloud of the Sun", published in The Monthly Notices of the Royal Astronomical Society ( 418 , 1272, 2011).
  A detailed review of Keplerian orbits and dynamics, and specifically the solution to Kepler's problem, is provided by C. D. Murray and A. C. M. Correia – see arXiv:1009.1738v1.
