Today is the #WinterSolstice in the northern half of the planet. It will occur in just over an hour’s time at 09:20Z, marking the start of #Winter, accompanied by the #LongestNight. Meanwhile, the other side of the #Earth is half a year out of phase and will mark the start of #Summer on their #SummerSolstice and the #LongestDay. By coincidence, the Earth is near #Perigee at this time of year, being its closest to the #Sun. in its very slightly #EllipticalOrbit. Actual pergee will occur on 4 January 2025.
