Perihelion Day!

Today is the day when Earth makes its closest approach to the Sun, around 2pm EST (New York time). If you live in the northern hemisphere, you might find it surprising that the Earth is closer to the Sun during winter than during summer, but it is. The difference in distance is "small," astronomically speaking, a bit under 5 million kilometers. Our most distant point from the Sun will happen on July 4th.
