A minor G1-class geomagnetic storm will hit Earth right as our planet reaches perihelion, its closest point to the sun.
On Jan. 4, Earth will reach its closest point to the sun all year in an annual event called perihelion. The precise distance varies from year to year, but perihelion 2023 will see our planet orbiting 91.4 million miles from the sun — or roughly 3 million miles closer than Earth's aphelion, its farthest point from the sun, which will occur on July 6.
However, this weak-ranking storm is not likely to have any lasting impacts on our planet or its inhabitants — so enjoy the cosmic light show if you can. The actual date of perihelion is always shifting, changing by about two days every century due to small quirks in our planet's orbit. In the year 1246, perihelion and the winter solstice actually occurred on the same day. Thousands of years from now, in the year 6430, perihelion will line up perfectly with the spring equinox on March 20, according to Live Science's sister site Space.com .
