What happens when the Sun crosses the Earth’s equator?

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.

What do we call the day when the Sun moves northward across the equator?

The sun crosses the equator travelling northward around March 21 and going southward on Sept. 21, in celestial events known as “equinoxes” (from the Latin for “equal night,” as day and night are of roughly equivalent length on these dates.) The exact dates vary a little bit from year to year because of leap years.

How often does the Sun cross the celestial equator?

What is solstice and equinox?

Equinox vs Solstice Equinox. Solstice. Time of the year when the sun is nearest to the equatorial plane giving equal lengths of day and night.
