Happy aphelion!


Today the Sun is at its furthest away from the Earth (SpaceWeather).

Today the Sun appears 1.7% smaller than average.

OK, and it's the middle of the summer, so that doesn't seem to make sense to us in the northern hemisphere. But of course it makes perfect sense to the people in the southern hemisphere today, in the dead of winter.

But did you know that southern hemisphere summers are not as warm as northern hemisphere summers? Even though the Earth is closest to the Sun during their summer? Read the article to find out why.

And if you believe the Sun goes around the Earth, well, it's up to you to come up with your own explanation.
