The subsolar pointon a planet is the point at which its sun is perceived to be directly overhead (at the zenith); that is, where the sun's rays strike the planet exactly perpendicular to its surface.

What day has 12 hours of daylight and 12 hours of darkness? Autumnal equinox: Date in the fall of the year when Earth experiences 12 hours of daylight and 12 hours of darkness, usually around September 23. Summer solstice: Date on which the Sun is highest in the sky at noon in theNorthern Hemisphere, usually around June 22.

Why is Vernal Equinox important? According to Space, though, the Vernal Equinox is even bigger than that: it's the mostimportant astronomical event of the year. That's because it marks the beginning of the astronomical year.

Why is September 22 the first day of fall? As the year elapses, the days slowly get shorter and cooler as summer gives way to autumn. On September 21 or22, the sun's direct light has reached the equator. Days and night reach parity, and because the sun is hitting the whole world head-on, every latitude experiences this simultaneously.

Why is it called vernal equinox? In the Northern Hemisphere, the March equinox is called the vernal equinox, because it signals the beginning of spring (vernal means fresh or new like the spring). The September equinox is called the autumnal equinox, because it marks the first day of fall (autumn).
