i am asking about the solar system i need some help. what is the timescale of darkness at the poles?

Answer 1

Define darkness.

Right at the poles, of course, you have six months of "day" and six months of "night." That said, it takes weeks before it is truely dark out...that is, no twilight on the horizon.

The true darkness of polar night only lasts a for two or three months.

Answer 2

I really have no idea what you mean by the "timescale of darkness at the poles", so, I'll guess at a translation into sensible english, and then answer that question:

"How long are days and nights at the north and south poles of the earth?"

Now, given that question: due to the tilt of the earth relative to its orbital plane (the earth's rotation axis is tilted 23.4 deg away from vertical), the exact north and south poles of the planet do not experience normal, 24 hour days. Rather, at the north pole, the sun drops below the horizon on the day of the autumnal equinox (Sep 22 or 23), and does not appear above the horizon again until 6 months later, on the day of the vernal equinox (Mar 20 or 21). The south pole experiences just the opposite: sunset on the Mar 20 and sunrise on the Sep 22.

Answer 3

If you are exactly at the pole, then it is half the year in darkness and half the year in daylight. The Sun rises in the spring, stays up all summer, sets in the fall and stays down all winter.
