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.
