What causes the stars to appear to make one complete circle around polaris every 24 hours?
The stars all rotate about an imaginary axis line that goes through the poles of the earth. From our veiw point, the fixed stars will move across the sky, corresponding to this spin. The polaris star is almost on this imaginary axis line - if you were to carry on extending it out to this star.
How many degrees of longitude does the sun appear to move each hour if it move 360 in 24 hours?
The sun appears to move 15 degrees of longitude each hour if it moves 360 degrees in 24 hours. This is because there are 24 hours in a day, so dividing 360 degrees by 24 hours gives us 15 degrees per hour.
Which star always appears in the same spot every night?
No, because the world is always spinning. Polaris (north star) appears in the same location (omitting precession, nutation, and polar motion) and the other stars appear to rotate counter clockwise around it. Alternately, stars appear to rotate clockwise around the south pole's celestial zenith (no "south star"). The stars will appear in almost the exact same spot each night as they were before at the same time. Because the earth rotates and tilts and revolves around the sun the stars will over the course of a year vary from where they appear at different times of year. _________________________________ We generally think of "one day" as being exactly 24 hours, but that's a "solar" day, with reference to the Sun. Because the Earth is moving in its orbit around the Sun, the Earth actually has to spin about 361 degrees for the Sun to appear in the same spot each day. The "sidereal" day, with reference to the fixed stars, is only 23 hours 56 minutes; that's how long it takes for the Earth to spin exactly 360 degrees, or one full circle. So the stars appear to rise about 4 minutes earlier each day.
Polaris declination and right ascension on Feb 5th?
On February 5th, Polaris has a declination of approximately +89 degrees 15 minutes and a right ascension of about 2 hours 31 minutes. These values may vary slightly depending on the year and time of observation.
How many degrees does the sun move in four hours?
The sun appears to move about 60 degrees in four hours. Of course, the sun is not moving, the earth is rotating making it appear to ancient people the sun is moving.
How many degrees do the stars move around polaris in 3 hours?
45 degrees

How many degrees do the stars move around Polaris at night?
The answer depends on how long the night is. With respect to distant stars the earth rotates once in every 23 hours 56 minutes and 4 seconds. Over that period, the stars will move through 360 degrees.
How far does the sun appear to move in four hours?
Through an angle of 60 degrees.
What is the duration of Fly Me to Polaris?
The duration of Fly Me to Polaris is 1.6 hours.
How many degrees of longitude does the sun appear to move each hour if it move 360 in 24 hours?
The sun appears to move 15 degrees of longitude each hour if it moves 360 degrees in 24 hours. This is because there are 24 hours in a day, so dividing 360 degrees by 24 hours gives us 15 degrees per hour.
How many credit hours are required for bachelor's degrees?
Bachelor's degrees typically require around 120 credit hours to complete.

What are the coordinates of the star Polaris?
In the celestial coordinate system Polaris is located at the following coordinates: Right Ascension: 02 Hours 48.2 Minutes (measured from 0-24 Hour format) Declination: +89 Degrees 19 Minutes (measured from +90 to -90 Degree format)
How many degrees of longitude does the sun appear to move each hour if it moves 370 degrees in 24 hours?
Any number you like. Since the predicate statement: "the sun appears to move 370 degrees in 24 hours" is FALSE, then the "conclusion" can be any statement you like. The sun appears to move 360 degrees in 24 hours and so 360/24 = 15 deg each hour.
