Happy Perihelion Day!

A friend whose business is to know these things assures me that at 3 PM today, the earth will have its closest approach to the sun. This may appear as little more than a cruel joke to areas of the planet currently under several feet of snow, but it's an excuse for a party. Break out the tropical hats, bermuda shorts and froo-froo umbrella drinkies!

And start planning for Aphelion Day, July 7!

hmm how much closer are we now compared to July 7th?

The difference is about 5 million kilometers, about a 3% variation.

In the present epoch the eccentricity of Earth's orbit is approximately

e=0.017

...to be snooty and mathy about it :-)

At this point in time, I'm just grateful in the fact that the days are getting longer. That extra 30 seconds - minute certainly makes a difference to me, especially on the North Coast.

Oh! My eyes... the glare... so... bright...

Oh, wait a minute, it's cloudy here.

It's supposed to hit the low fifties today in my area.

I'm wearing shorts.

Golly, I had always thought "perihelion" was another name for a pouty, rosy man-bud. Thanks for the heads-up!

Aren't you glad you learned different here instead of, say, your next office party?

And don't forget to mark your calendar on Sunday (7 January) as the latest sunrise of the year in the DC area!
