The word you're fishing for is "equinox", but I know for a fact that it is not the position
that the sun reaches. I've been unclear on whether it's the place in the Earth's orbit
where the axis is not inclined toward or away from the sun, or the point in time when
the Earth reaches that place. In order to answer your question with some confidence,
I went off elsewhere and immersed myself in literally minutes of concentrated research
on the topic. I have learned that the equinox is the point in time.
Its is cooler because of earths tilt the sun's ultraviolet rays hit most directly on the equator so it is hotter by the equator so the farther from the equator the cooler.
Climates farther from the equator receive less direct sunlight due to the curvature of the Earth, resulting in cooler temperatures. Additionally, the angle at which sunlight reaches the Earth's surface at higher latitudes leads to less heat being absorbed, contributing to cooler temperatures in these regions.
Celestial Equator
If you are right at the Equator, you will not be able to see Polaris. If you could, it would be right on the horizon, but ground haze and obstructions would almost certainly hide it from view.

Summer and winter
Because the sunlight it receives is almost directly overhead all year round. the Equator receives the most solar energy.

Many countries do not cross the equator.

The tilt of earths axis makes the equator appear to be sideways.
The equator goes though South Africa, Africa and new Guinea
