About 9.45 trillion kilometers (5.88 trillion miles) per year if you mean how far can light (including the sun's light) travel in a year.
365 days/year * 86,400 seconds/day * 299,792 km/s = 9.45 x 10^12 km/year
solstice
The tropic of Cancer is 23° North of the Equator. It represents the point where the Sun can be directly overhead. If you are any further north, the Sun can not be overhead. The corresponding feature in the southern hemisphere is the Tropic of Capricorn. As to the Sun's direct rays, they can be anywhere from the South Pole to the North Pole. Those two points and everything in between receives the Sun's direct rays at some time during the year.
The distribution of incoming solar radiation during the course of a year is exactly equal at both poles, and neither of them ever receives any 'direct' rays.
Yes - for half the year.
They get the most direct rays from the sun.
December 21 or 22, coinciding with the Winter Solstice in the northern hemisphere.

The Equator is the point around the earth where the distance the suns rays have to travel through the atmosphere to reach the Earth is the shortest. At that point it shines almost directly down all year around.

The sun's rays shine most directly at locations near the equator. These areas receive more direct sunlight throughout the year, leading to warmer temperatures and more consistent daylight hours.
Equator.
Twice.
There's no place where the angle of the sun's rays doesn't change. But the place thataverages the most direct rays for the longest time in the course of a year is the equator.That's zero latitude.That's probably why it's so warm there.
Temperature changes from month to month due to variations in the angle of sunlight, Earth's tilt, and distance from the sun. These factors affect the amount of heat and light received at different times of the year, leading to the fluctuation in temperatures.

It depends on how much atmosphere it has to go through, the further away FM the equator you are the more the earth curves so the suns rays enter at an angle, meaning that it has to go through more atmosphere. Whereas on the equator the suns rays travel strait so there is less atmosphere to go though, make the suns rays more intense
