Celebrate Perihelion

Today, the Earth will be at a point in its orbit around the Sun called perihelion; the point in its orbit about which it is closest to the Sun. Until early July, we’ll be getting further and further away from the Sun, after which point we start getting closer again.

The overall change in distance is quite small, comparatively. Today, we’re approximately 3.1 million miles (just shy of 5 million kilometers) closer to the Sun than we will be in July, at aphelion. When you compare that to an average distance of around 93 miles, you’ll realize why the change in distance is virtually unnoticed by us Earthlings (unless we’re scientists specifically studying the Sun).


That distance has a negligible impact on the temperatures on Earth. It’s the amount of direct sunlight we receive, based on the Earth’s axial tilt, that gives us our seasons and varying temperatures.
