So close, yet so far. Earth at Perihelion

We've reached perihelion! Two weeks after winter solstice, the Earth's orbit is closer to the Sun than at any other time of year - a result of the Earth’s elliptical orbit. You may think: 'If we’re so close to the Sun, why can’t I feel the heat?' Well, that's because we're only receiving about 7% more solar energy than normal, which doesn’t really have much impact on the weather.
