Does the right ascension and declination of the star Arcturus change with the change of month or is it the same throughout the year?

Basically they stay the same, although over tens of thousands of years, they change slightly.

How much does the right ascension of Betelgeuse change from midnight to 6am?
It doesnt change. The RA is related to the mm/dd/yy by a factor of pi/6. Consider this from Oct21 to Dec21 when Orion is rising in the east. Good Luck..
Why the arrangement of the constellations doesn't change throughout the seasons?
The stars in the sky don't change, just our position under them.
How does the sun change throughout the year?
The rotation around the sun the cause a shift.
Do you see the same stars when you look out at night?
The Earth's axis always changes so you will see some stars one night but they change throughout the year
Does earth's revolution around the sun change both the right ascension and the declination of a star?
yes
What direction is the Gemini constellation?
The direction will change all the time, due to Earth's rotation. It's approximate coordinates are: right ascension = 7 h, declination = +20°. If that doesn't mean anything to you, it would probably be easiest to have a friend who knows a bit about astronomy point it out to you.
When does the Sun have declination 0 degree today but will have a negative declination tomorrow?
Declination is the angular measurement of a celestial body north or south of the "celestial equator". You can think of it as the equivalent of "celestial latitude". The "fixed stars" don't have any change in declination. (Well, they _DO_, but only very slightly and VERY slowly.) The Sun, Moon, and planets all have their own paths within the solar system, so their declinations will change on a day-to-day basis. The Sun is at a declination of zero precisely at the time of the equinox. In September, the Sun's declination is decreasing, and it goes negative immediately after the moment of the equinox. This is generally on September 21, but this can vary a day either way depending on the cycle of leap years.
The angle of difference between the geographic and magnetic poles is called the declination How does the declination change as you move north from where you live?
The angle between the geographic and magnetic poles extends more towards the east, as you move to the north. The magnetic pole is actually near Greenland.
Why is it important to know an area's magnetic declination?
It may not be important, but it IS a matter of wide interest, because it determines the length of daylight and darkness everywhere on Earth, as well as the onset of each change of seasons.

Why does the moon cross the equator twice each lunar month?
The moon crosses the equator twice each lunar month due to the moon's change of declination.
When using a compass to map an area why is it important to know an areas magnetic declination?
Unlike the geographic poles, which are always in the same place, the magnetic poles change location throughout the history of earth. So when using a compass to map or explore the Earth's surface, you need to make a correction for the difference between geographic nor and magnetic north.
What is a character that does change throughout the story?
Characters that change throughout a story are called dynamic characters.Characters that do not change throughout a story are called static characters. (think of the static on TV. it stays the same.)
