Equinox – National Geographic Society
19 oct. 2023An equinox is an event in which a planet’s subsolar point passes through its Equator. The equinoxes are the only time when both the Northern and Southern Hemispheres experience roughly equal amounts of daytime and nighttime. Learn about the science, the causes, and the cultural significance of the equinoxes on and other planets.

Learn how Earth’s position in its orbit relative to the Sun defines the solstices and equinoxes, and why they are called so. The equinoxes occur when the Sun is directly overhead at the Equator, and the solstices when the north or south pole points towards the Sun.

28 déc. 2023The Sun’s vertical rays strike the Earth at the equator (0°) on the March equinox (March 20) and the September equinox (September 21). The March equinox is known as spring in the northern hemisphere and fall in the southern hemisphere, while the September equinox is known as fall in the northern hemisphere and spring in the southern hemisphere.

Climate and Past Weather Local Programs The Equinox (Vernal & Autumnal) 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.

What Is the Equinox? And What Is the Solstice? – timeanddate.com
Equinoxes and solstices are a result of two things: Earth’s tilt and its orbit around the Sun. Earth, like nearly all the planets, orbits the Sun in a tilted fashion. Earth spins once a day on its axis of rotation, an imaginary line running through the North and South Poles. The spinning Earth orbits the Sun once a year, tracing out an …

Equinox – Wikipedia
A solar equinox is a moment in time when the Sun crosses the Earth’s equator, which is to say, appears directly above the equator, rather than north or south of the equator. On the day of the equinox, the Sun appears to rise due east and set due west. This occurs twice each year, around 20 March and 23 September.. More precisely, an is traditionally defined as the time when the …

The celestial equator is 0° DEC, and the poles are +90° and -90°. Right ascension (RA) is the celestial equivalent of longitude. RA can be expressed in degrees, but it is more common to specify it in hours, minutes, and seconds of time: the sky appears to turn 360° in 24 hours, or 15° in one hour. So an hour of RA equals 15° of sky rotation.

Solstice – National Geographic Society
19 oct. 2023A solstice is an event in which a planet ‘s poles are most extremely inclined toward or away from the star it orbits. On our planet, solstices are defined by solar declination —the latitude of Earth where the sun is directly overhead at noon. On Earth, solstices are twice-yearly phenomena in which solar declination reaches the Tropic of …
