Source: https://www.livescience.com/perihelion-solar-storm-2023 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 (147 million kilometers) from the sun — or roughly 3 million miles (4.8 million km) closer than Earth's aphelion, its farthest point from the sun, which will occur on July 6. . . .

Hmm Tax Day, Flag Day, Some Day, and Christmas. Coincidence? What Is the Equation of Time? On average, the Sun crosses the meridian in Greenwich at precisely 12:00 GMT. In reality, this only happens on four days of the year, around the following dates. (We’ve used Greenwich as an illustration, but the equation of time applies to all locations across the world.) Date Time of solar noon in Greenwich April 15 12:00 GMT June 14 12:00 GMT September 1 12:00 GMT December 25 12:00 GMT This is when solar noon and clock noon are equal.
