Redditor jb2386 created this mind-blowing image which shows what Jupiter would look like if it was the same distance away from the Earth as the moon. He figured it out by taking a source picture that had the moon in it, used the correct scale of the Moon to Jupiter and then placed the readjusted size of Jupiter in the image. Because of the planet's enormous size, we are only seeing about a quarter of Jupiter in the frame! Unfortunately, as cool as it looks, it appears we'd be goners if this actually happened in real life.
