How many degrees do the stars move around polaris in 3 hours?
45 degrees
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.
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.
Why doesn't Polaris seem to move?
The apparent "movement" of the stars through the night sky is due to the rotation of the Earth. The observer on Earth is going around in a big circle every day. The center of that circle is the axis of rotation of the Earth. (The longer term movement due to the orbit around the Sun every year does not affect the apparent position of the stars because they are so far away.) Polaris is (almost) in line with the Earth's axis of rotation. At night, as the Earth rotates, Polaris appears to stay at one point in the sky as the sky rotates around it. That point is the North Celestial Pole. Polaris is used for simple navigation because it is at a height in degrees above the horizon equal to your North latitude. (At the North Pole it would be straight up, so 90 degrees. In London, for instance, that number is 51½ degrees.)
Why do the constellations appear to rotate around Polaris?
The constellations appear to rotate around Polaris due to the Earth's axial rotation. As the Earth spins on its axis from west to east, the stars in the night sky seem to move in circular paths around Polaris, which is located nearly at the North Celestial Pole. This motion is a result of our perspective from the Earth's surface, creating the illusion of a rotating sky while the stars themselves are actually stationary relative to each other.
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.
How can one locate Polaris in the night sky?
To locate Polaris in the night sky, find the Big Dipper constellation and follow the two outer stars in the bowl of the dipper to locate Polaris, which is the brightest star in the Little Dipper constellation. Polaris is also known as the North Star and is located almost directly above the North Pole.
If you went out at night and every star in the sky rose and set except for Polaris where could you be?
If every star in the sky rose and set except for Polaris, you would be at the North Pole. Polaris, also known as the North Star, is located almost directly above the North Pole, making it appear stationary in the night sky while other stars appear to rotate around it.
