The artwork above looks like Earth with a Saturn-like ring, i.e. our planet without its moon.
So: what would our world be without its moon (other than un-romantic)?
"Life would be: Migratory and on shorter day-night cycles, if existent at all. Huge tides generated by the moon — which orbited much closer to Earth when it formed — washed the chemical building blocks for life from land into the oceans and helped "stir up the primordial soup," said Neil Comins, a professor of physics at the University of Maine.
"The moon's gravity has helped slow Earth's rotation from an initial six-hour day to our current 24-hour day, while also stabilizing the tilt of our planet's axis, and thereby moderating the seasons."
