How many degrees do the stars appear to move around Polaris in 3 hours?
Stars appear to move around Polaris, the North Star, due to the Earth's rotation. In three hours, the Earth rotates approximately 45 degrees (360 degrees in 24 hours). Therefore, stars appear to move about 45 degrees around Polaris during that time.
Stars move around polaris at what degree?
15 degrees per hour.
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.
What is the temperature of Polaris in Celsius?
Polaris is a multiple star system; each of the stars that make it up has its own surface temperature. For more details, I suggest you take a look at the Wikipedia article on "Polaris".
How do the stars appear to move near Polaris?
Polaris traces out a circle with a diameter of 1.5 degrees above the North Pole. Other nearby stars trace out larger circles.
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.
What appears to revolve around Polaris due to earth's rotation?
Due to the vast distance between the earth and polaris, the earths axis of rotation essentially lines up with polaris at all times, so when the stars are visible, and viewed from the north pole, the earths rotation causes the stars to appear to rotate around polaris.
What causes the circumpolar stars to appear to move around polaris?
The apparent daily movement of the stars in the sky is a reflection of Earth's rotation. Earth rotates around its axis; as a reflection of this, the entire sky rotates around an "axis", which is simply the extension of Earth's axis. By chance, the star Polaris is almost exactly on the line of the Earth's axis, extended into space. So, as the Earth rotates the stars appear to rotate around Polaris. Circumpolar stars never go below the observer's horizon, so they just seem to go in circles around Polaris.
Which of these stars is closest to the earth Polaris Antares or Betelgeuse?
Polaris is the closest of the three stars.
Circumpolar constellations orbit what?
Beautiful question !! Circumpolar stars and constellations are stars and constellations the "go around the pole" = Circum (circle) polar (the pole) The North Star is called "Polaris" because it's directly above Earth's North Pole - in other words, if you went to the North Pole, "polaris" would be directly over your head. Because of this, all of the stars appear to pivot around Polaris as Earth rotates. Now I don't know where you live, but if you live in the United States, Polaris would NOT be overhead - it would be lower in the sky but still in the North. The lower on the globe you live, the lower Polaris appears in the sky. So, the stars and constellations that spin around Polaris but DON'T SET, are called circumpolar stars and constellations.
Why do the stars appear to rotate around Polaris?
It's an illusion caused by the actual rotation of the earth.
What is the altitude of Polaris if your latitude is 41 degrees south?
You would never see Polaris there because it would always be 41 degrees or more below the northern horizon. On the other hand you can see many fine stars and constellations that are never seen in North Europe or the north of the USA and Canada.
