You Could Fit All The Planets In Our Solar System Between Earth And The Moon

Picture of moon in space

At apogee, when the Moon is farthest from the Earth, it's about 398,000 km surface-to-surface.

If we align the planets through their polar axes, they add up to a total distance of 364,799 km.

    Saturn's Moon Titan Is The Only Known Place In Our Solar System Other Than Earth That Has A "Liquid Cycle"

    Picture of moon Titan with liquid cycle

    It is the sole other place in the Solar System known to have an earthlike cycle of liquids raining from clouds, flowing across its surface, filling lakes and seas, and evaporating back into the sky (akin to Earth’s water cycle).

    Unfortunately, this reverses when you return to full gravity. And, apparently, the shrinking process hurts.

    The Sun Is Predicted To Be A Little Less Than A Half Through Its Lifespan

    Picture of sun

    The Sun will eventually run out of energy, like all stars do.

    When it starts to die, the Sun will expand into a red giant star, becoming so large that it will engulf Mercury and Venus, and possibly Earth as well.
