Yes, the Earth is closest to sun on January 2/3 for this entire year, but don’t expect to feel it.

It certainly will not feel any warmer where I am (actually it’s colder than yesterday and tomorrow is even colder). This perihelion will happen at night (10:35 p.m. EST) for me and it will be quite cold then. (It happens on the morning of January 3 5:35 UTC in Europe and Africa.) Perihelion, from the Greek roots peri (near) and helios (sun), will bring us within 91,401,983 miles (147,097,233 km) of the Sun. Though we won’t feel any hotter, Earth is about 3 million miles (5 million km) closer to the sun in early January than it is in early July. This happens every year in early January. And we will be farthest away (aphelion) from the sun in early July. Seems counterintuitive to us in the Northern Hemisphere.

The difference in distance between perihelion and aphelion isn’t that much because Earth’s orbit is very nearly circular. That is why the tilt of our world’s axis is what creates winter and summer on Earth. My Northern Hemisphere is tilted away from the sun now, so it is winter.  The day of maximum tilt toward or away from the sun is the December or June solstice, but even that won’t make for the hottest or coldest days of the year. This tilting may make seasons, but atmospheric conditions make our weather change. I blame those Arctic blasts for my car’s dead battery this morning.

It’s quite hot on this summer day here in Paradelle, but the Earth is just reaching its most distant point from the sun for 2015 as I type this line.

July 6, at 19:41 Universal Time or 3:41 p.m. Eastern Daylight Time in Paradelle is when our home planet is farthest from the sun. This happens every year in early July.

But it’s a hot day as I walked outside today to get lunch.  We may be at our furthest distance (called aphelion) now, but, like most things, it is temporary.

Our journey around that precious star is not quite circular, so we are farther away from the sun in early July than at other times of the year. It’s five million kilometers farther from the sun than we will be in January but in the numbers of space and time that’s not a lot.

Look up at the ball of fire. It is 94,506,507 miles away (that’s 152,093,480 kilometers to most Earthlings) away.  Not so far away; not too close. A nice cosmic distance.


We have circled the Sun once again.

Today we’re as far away as possible.

Apo – away – from Helios, Greek Sun god.

A summer-hot day, an imperfect circular journey.

Aphelion and 3,000,000 miles doesn’t matter much.

We believed we would live together forever. When frozen lakes break Skating down there... Winter is quite democratizing when it comes to trees. This little deer 🦌 is a local all year but what is the next critter doing here?  Shouldn’t he being hibernating somewhere? 🐻 Stream of consciousness 2: calming the turbulence.
