    The moon is approximately 384,400 km from the Earth, which isn't that far, in astronomical terms.

    But what if it was a whole lot closer?

    Check out the video above, which shows what the moon would look like if it was only 400 km away.

    Having a moon just a hop, skip and a jump away would do more than change the look of the sky.

    According to the video's creator,  the close proximity would cause the moon to rise in the west and set in the east.

    In normal conditions, the moon's orbit is slower than Earth's, making the moon rise in the east and set in the west. But at the distance depicted in the film, its orbit would become faster than Earth's, causing it to rise in the west and set in the east.

    But in reality, there's no way the moon could ever get that close to our planet.

    Having a moon only 400 km away would evoke fierce tidal forces that would alter the look of our land. 

    And, as Yahoo News points out, the Moon needs to stay a minimum of 9,500 km away, lest it be torn to shreds and the Earth destroyed.
