When the Sun is at its highest point above the celestial equator it is at the?

Solution: On Earth’s equator, the celestial equator passes through the zenith. On March 21, the Sun is crossing the celestial equator, so it should be found at the zenith (90°) at noon. On June 21, the Sun is 23° N of the celestial equator, so it will be 23° away from the zenith at noon.

What is the day called when the Sun reaches a point on the celestial sphere 23.5 degrees south of the celestial equator?

The first qualitative change occurs at 23.5° latitude, where the noon sun on the June solstice passes directly overhead. This latitude is called the Tropic of Cancer. Farther south, in the so-called tropics, the noon sun will appear in the northern sky for a period of time around the June solstice.

What occurs when the Sun crosses the celestial equator?

At the equinox, the sun crosses the celestial equator to enter the sky’s Northern Hemisphere. We have an equinox twice a year – spring and fall – when the tilt of the Earth’s axis and Earth’s orbit around the sun combine in such a way that the axis is inclined neither away from nor toward the sun.

How often does the Sun cross the celestial equator?

There are two equinoxes every year: one in September and one in March. In September, the Sun crosses the equator from north to south. At the equinox, Earth’s axis is perpendicular to the Sun’s rays as the Sun is directly above the equator.

How many times each year does the Sun pass through your zenith if you live on the equator?

Once or twice each year, people who live at lower latitudes (within 23.5 degrees of the equator) can see the sun reach the zenith, an imaginary point directly overhead. (If you poked a pencil straight into the ground when the sun was at its zenith, it would make no shadow at all.)

What happen when a side of the earth is facing away the Sun?

As Earth rotates, the side of Earth facing the Sun experiences daylight, and the opposite side (facing away from the Sun) experiences darkness or nighttime. Since the Earth completes one rotation in about 24 hours, this is the time it takes to complete one day-night cycle.
