- Planetary Conjunctions
This little tool calculates how long any two bodies in orbit about the sun will take to reach their current angular positions again relative to each other. The defaults are Mercury and Earth. Mercury's "year" is just about 88 days, but because the Earth is moving, getting into the same alignment takes about 116 days.
