CROP CIRCLE - June 25 2012 (Mercury's Solar Orbit)

Mercury turns relatively slow. One rotation (spin) is equal to about 58.65 Earth days. 

From our perspective It orbits the Sun once every 88 Earth days. or 1.5 Mercury days per year (rotations per revolution). 

This is not a coincidence, but the result of gravitational interactions with the Sun, and gives Mercury 3 spins for every 2 orbits. or 3 mercury days for every 2 mercury years 

With the planet rotating in the same direction as it orbits, the "apparent solar day" (sunrise to sunrise) is actually two of its years, about 176 Earth days. 

An observer on the planet would see the Sun come up, move across the sky, then hover or even back up in its motion, and then finally set after 88 days of daylight. Some locations would see it rise, reverse back below the horizon, and then rise again. The stars would still move across the sky at a slow but steady pace.
