Name of country where the sun shines directly over the equator on 21st March?
The Sun is directly over the equator on both the Vernal and Autumnal equinoxes. The Autumnal equinox is usually on the 21st or 22nd of September but can occur as late as the 23rd. On both equinoxes however all of the countries along the equator will have the sun pass directly overhead. It will rise due East, be directly overhead at noon and set due West.
Does The celestial equator always pass directly overhead?
No, the celestial equator does not always pass directly overhead. The position of the celestial equator in the sky is determined by the observer's latitude on Earth. If the observer is located at the equator, the celestial equator will pass directly overhead. However, for observers at different latitudes, the celestial equator will appear at an angle to the horizon.
At what latitude is the noon sun at zenith?
That may happen - at different times of the year - in any latitude between the tropics - that is, between 23.5 degrees north, and 23.5 degrees south. Note that this angle is precisely the tilt of Earth's axis.
Can you see earth by head up from moon?
I imagine so, near the lunar equator the Earth will pass close to directly overhead.
Why sun appears oval at sunrise and sunset but appears circular at noon?
At sunrise and sunset the sun is near the horizon. The rays of light from upper & lower part of the periphery of the sun bend unequally on travelling through earth's atmosphere. That is why sun appear oval or flattened at sunrise and sunset. At noon sun is overhead. The rays of light from the sun enter earth's atmosphere normally. Therefore they suffer no refraction or bending on passing through. Hence the sun appears circular at noon.
How many days a year does the sun pass directly overhead at 25 degrees latitude?
452,4000000
How often does the sun pass directly overhead when observed from Lagos Nigeria between November 1st and December 31st each year?

Why is the overhead pass or set important in volleyball?
The overhead pass is an important skill for passing a ball and making a set to attackers
What started the system of the standard time that we use today?
The railroads. When railroading started, time was based on the position of the sun: when it is directly overhead, it's "noon." Or, on a clock, 12:00. The problem with that is, what is "noon" in Chicago is not noon in Detroit or Milwaukee. This makes it hard to calculate timetables--if it takes an hour to go from Alphaville to Bravoville, you then have to work in a time correction factor. Worse: if a train leaves Alphaville going to Bravoville at noon, and a train leaves Bravoville going to Alphaville at noon, they're going to reach their destinations at different times. So, they came up with a "standard time" deal. They divided the nation into four sections, because it takes four hours for the sun to pass across the US. Then they decided noon would be when the sun got to the middle of each section. Now, if a train leaves Bravoville for Alphaville at noon and one leaves Alphaville for Bravoville at noon, they'll both reach their destinations at the same time.
What are all the different Basketball passes?
Chest pass, overhead pass, bounce pass, baseball pass
What does overhead pass mean?
An overhead pass is a pass thrown overhead. This is done by grabbing the ball with both hands and bringing it behind your head. After that, just chuck the ball forwards. That is an overhead pass.
Do both the Earth and Sun pass directly overhead when viewed from the lunar equator when observed from the moon?
No. The moon actually splits in two and thats how the eye percieves it as one.
