Earth will be at its closest point in its orbit around the Sun (perihelion) tonight when it is 91.4 million miles away. It will be 3.1 million miles further away on July 3, 2019. We’re closer to the Sun in (our) winter!
Why is it cold this time of year even though we are closer to the sun? Well this all has to do with the tilt of the Earth. The northern hemisphere is tilted away from the sun in January so there is less direct sunlight from the sun. During the summer, the earth, is tilted toward the sun and the more direct sunlight gives us warmer weather. You can learn more about the tilt on the video below.
