Happy New Year! Though you likely won’t be able to tell the difference, Earth is at its closest to the Sun for the year this month, January 2020. Perihelion, the point in Earth’s annual orbit where it’s closest to the Sun, occurs each year in early January. This year, perihelion occurs at 1:48 a.m. Chicago time on […]
