Jun 20, 2023 · Solstices happen twice per year, at the points in Earth’s orbit where this tilt is most pronounced. These days are the longest (in the summer hemisphere) and shortest (in the winter hemisphere) of the year, and mark the change of seasons to summer and winter, respectively.
Sep 22, 2023 · Tomorrow’s September equinox signals the change of season, from summer to fall in the Northern Hemisphere and from winter to spring in the Southern Hemisphere. But why do Earth’s seasons change?

There are only two times of the year when the Earth's axis is tilted neither toward nor away from the sun, resulting in a "nearly" equal amount of daylight and darkness at all latitudes. These events are referred to as Equinoxes. The word equinox is derived from two Latin words - aequus (equal) and nox(night). At the equator, the sun is directly ov...
The summer solstice occurs at the moment the earth's tilt toward/from the sun is at a maximum. Therefore, on the day of the summer solstice, the sun appears at its highest elevation with a noontime position that changes very little for several days before and after the summer solstice. The summer solstice occurs when the sun is directly over the Tr...
We all know that the Earth makes a complete revolution around the sun once every 365 days, following an orbit that is elliptical in shape. This means that the distance between the Earth and Sun, which is 93 million miles on average, varies throughout the year. During the first week in January, the Earth is about 1.6 million miles closer to the sun....
There is a lag between the longest day of the year and the warmest average temperatures for most mid and high-latitude locations. In northern OH/Northwest PA, the maximum daily temperature occurs nearly 3 weeks later in mid-July. Just as the warmest part of the day usually occurs several hours following noon, when the sun is highest in the sky, so ...
Oct 10, 2023 · If you live in Earth's middle latitudes, you're accustomed to experiencing four traditional seasons: winter, spring, summer and fall. That existence in the two bands stretching across the planet from 30 to 60 degrees both north and south of the tropics offers a lot more variety, weather-wise, than on the equator, where there's basically a hot ...
Nov 12, 2023 · Uranus has unusual seasons, in contrast to Earth and the other major known planets. It’s because Uranus’ spin axis lies nearly sideways with respect to the plane of its orbit around the sun.
