a harvest moon appears that night but nothing happens to the sun.
winter
The first day of autumn in 1974, also known as the autumnal equinox, occurred on September 23. During this day, day and night are approximately equal in length as the sun crosses the equator. This phenomenon marks the official start of the fall season in the Northern Hemisphere.
In the northern hemisphere, the autumnal equinox marks the first day of fall. An equinox happens twice a year, when the sun shines directly on the equator and the length of day and night is nearly equal.
Fall, and then Winter. Depending on your latitude, it may get cold. Or VERY cold.
From around 20 March to around 22 September, the sun is directly over the northern hemisphere. From around 22 September to around 20 March, the sun is directly over the southern hemisphere.
First you get day, then you get night.
In the northern hemisphere, the autumnal equinox marks the first day of fall. An equinox happens twice a year, when the sun shines directly on the equator and the length of day and night is nearly equal.
The planets will fall into the sun and get destroyed.

It will fall into the black hole. The same happens if something gets too close the Sun, for example - it will fall into the Sun.
The first day of fall is formally known as the Autumnal Equinox, and the word equinox means equal night; it is a day that is exactly the same length as the night. This is (in a sense) an extraterrestrial event in that it involves not just the planet Earth, but also the sun. It concerns the specific time at which the sun rises and sets.
Meteorologists don't choose the first day of fall. It is the point during the Earth's revolution around the sun at which the equator is perpendicular to the sun. Neither the Northern nor Southern hemispheres are tilted toward the sun. Astronomers determine when this is.
When the sun rises to begin the new day, night fall ceases.
sunny day
This happens twice a year at on of the "equinox" (the spring equinox or the fall equinox) At noon if you are on the equator at thet oment the Sun is at the "Zenith".
The Earth Begins To Tilt Away From The Sun & The Days Are Shorter & Colder.
