COMMENTS
"Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that generally repeats every 243 years, with pairs of transits eight years apart separated by long gaps of 121.5 years and 105.5 years. The periodicity is a reflection of the fact that the orbital periods of Earth and Venus are close to 8:13 and 243:395 commensurabilities." - Wikipedia
a(n) is approximately 365.25 * A171467(n+46). - Charles R Greathouse IV, Jan 24 2013
