Where do you have to be on the Earth to see the Sun at your zenith? If you stay at one such location for a full year, on how many days will the Sun pass through the zenith?

The sun can only appear at zenith between the Tropic of Cancer (latitude 23.5 North) and the Tropic of Capricorn (latitude 23.5 South).

Between those latitudes, it will pass by zenith twice a year: once the way north and once on the way south (at noon).

At the tropics of Cancer and Capricorn, it will only reach zenith on the summer solstice (once).

Thankyou!!!!!

To see the Sun at your zenith, you need to be located directly on the equator at noon. This point is known as the equatorial line or equatorial plane. The Sun reaches this point twice a year, during the equinoxes.

The equinoxes occur around March 20th (Vernal Equinox) and September 22nd (Autumnal Equinox). On these dates, the Sun is directly overhead at noon on the equator. Therefore, if you were to stay at the equator for a full year, the Sun would pass through the zenith on these two days.

To see the Sun at your zenith, you need to be located on the Tropic of Cancer (23.5 degrees North) on the June solstice. The zenith refers to the point directly overhead, so when the Sun is at its highest point in the sky, it will appear at your zenith.

If you were to stay at this location for a full year, the Sun would pass through your zenith on two specific days. The first occurrence would be on the June solstice, around June 21st. On this day, the Sun reaches its highest point in the sky during the year. The second occurrence happens during the December solstice, around December 21st. However, during the rest of the year, the Sun will not pass through your zenith at the Tropic of Cancer.

It's important to note that although the Sun is directly overhead (at your zenith) on these two specific days, there are other days in the year when it may come close to the zenith, but not exactly reach it.
