On January 5, 2020, the Earth will be the closest it will ever get to the Sun in the 21st century, at a nice and cozy distance of 91,398,199 miles. The pair will be about a million and a half miles nearer to each other than they are on average, which is over six times the distance from the Earth to the Moon. Since it’s in vogue to call large full Moons “supermoons”, I would like to dub this event the “supersun”. Of course, there’s a lot to the hows and whys and what it means other than “it’s big and close”, so I wanted to spend some time talking about it.
