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.
Where do you get your beautiful photos in your headers. Do you take them yourself? I loved this one – so appropriate. Cheers and happy New Year. B

Some are my photos but a bunch of them are actually taken from Google Earth aerial photos.
