Happy Perihelion Day!!

Welcome Sun!   Right now it is -1F on my back porch, but that doesn't matter, because it is Perihelion Day!

That's right - today is the day (at 7am EST) that the Earth is closer to the Sun than at any other time during the year!  We are 5 million kilometers closer than we are in July.

The Sun even looks larger (don't look at the Sun).

So for all those who think that the seasons are caused by how close we are to the Sun, neener, neener, neener!



It is the tilt of the Earth's axis that causes the seasons.
