Celestial mechanics. It truly is like clockwork.
Take a moon a quarter the size of it’s primary planet, put it out a quarter million miles, let angular momentum and four and a half billion years roll by, and it ends up right there tonight, headed for right THERE in twelve days and thirteen hours. Mix in an atmosphere, some haze and fog, diffraction, refraction, Reyleigh scattering, and you end up with a weird looking arc of bright orange peeking over the horizon.
Whip out that cell phone, hold really, REALLY still, and maybe you see this.
Wonders abound, all around us.
