Word of the day: aphelion

This is the point at which the Earth is furthest from the sun. It occurs because the earth’s orbit is not circular but mildly elliptical.

The precise moment of its occurrence this year is 23.27 BST today 5 July. At this point, we will be 5M kilometres further from the sun than in early January when we were at the nearest point called the perihelion.

Enjoy the moment.
