Mars years
42 ≈ 79
Calculated
Forty-two Mars sidereal years in seventy-nine Earth sidereal years
Seventy-nine Earth sidereal years contain very nearly forty-two Mars years · about two days of drift over the whole span.
What it supports
A reproducible ratio of published orbital periods. 79 × 365.256 ÷ 686.980 ≈ 42.00. Recovered on Redworld’s clock, not invented here.
What it does not
Not a property of the rust, and not a reason 42 was waiting on Mars. Other integer pairs approximate the same year-ratio.
