Supermoon

Supermoon, where you stand.

You stand at the middle of your horizon. The dots are the moon’s path tonight, the moon lit as it is; the stage opens three hours after sunset. Slide through the night, or drag the sky to turn it.

How Sol measures it.

The orbit's distance runs from about 356,000 to 407,000 kilometres. The nearest full moons of a year are the ones called super; the farthest are sometimes called micro. Sol draws each of the year's full moons at its apparent size, so the difference can be seen rather than believed.

Words beside it.
