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.
Which of these terms means a complete circle around the sun?
The planets revolve around the sun. The planets rotate on their own axis.
What is the number of degrees the earth takes to revolve around the sun each day?
Every complete circle is 360o.
Which of these combined with the prime meridian makes a complete circle around the earth?
The International Date Line combined with the Prime Meridian makes a complete circle around the Earth. The Prime Meridian is at 0 degrees longitude, and the International Date Line is opposite it at 180 degrees longitude.
What is polaris a name for?
Polaris is the name of the north pole star. It isn't EXACTLY above the North Pole, but pretty close; only about one-half a degree off. If you were to watch Polaris through the night, you wouldn't notice any movement, but in a long-time-exposure photo, you can see that Polaris makes a TINY circle around the perfect North.
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 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 is the largest circle that you can draw around Polaris without running into the horizon?
It's the circle whose radius is the same as your north latitude. (That means it depends on where you are, and if you're south of the equator, Polaris is below your horizon anyway and there is no such circle.)
Constellations that circle polaris and are visible year around are called?
These are called circumpolar constellations.
Does the big dipper circle the pole star?
Because of the special position of the pole star Polaris in our sky, _ALL_ of the stars appear to rise in the east and set in the west, or to circle Polaris. Stars close to Polaris in the sky, including the stars that make up the Big Dipper, do seem to circle Polaris. In reality, of course, it is the Earth itself which is spinning and taking us along for the ride. From the perspective of an observer elsewhere in the solar system, all of the stars including Polaris appear to be fixed in space and unchanging. Over the course of thousands of years, the constellations that we know will be distorted and become broken, as each star follows its own path through the Galaxy.
A rainbow viewed from an airplane may form a complete circle where will the shadow of the airplane appear?
The shadow of the airplane will appear at the center of the complete circle formed by the rainbow. This is because the shadow is always cast opposite to the direction of the sunlight, and the sunlight is directly behind the airplane when a complete circle rainbow is seen.
Constellations that circle Polaris are circumpolar?
Yes, they are.
Explain why polaris does not appear to move relative to the northern horizon during the year?
Because the Earth's axis of rotation currently points very near the star Polaris. This is a coincidence of timing; if we were living several thousand years ago, then it would be Vega that appeared to be fixed in the night sky (the Earth actually wobbles very slowly as it spins, taking about 23,000 years to make a complete circle).
Does a rainbow look circular from space?
Yes, a rainbow would appear as a full circle when observed from space because it forms a complete circle around the antisolar point, which is directly opposite the sun. This phenomenon is called a "full-circle rainbow" or a "360-degree rainbow."
Constellations that circle polaris are?
These are called circumpolar constellations.
Why does the number of circumpolar constellations depend on latitude?
Circumpolar Constellations are those that appear to circle the North Star, Polaris. Polaris' place in the sky changes based on the viewers latitude. The closer you get to the North Pole, the higher in the sky Polaris appears, and therefore the more constellations appear to spin around Polaris.
In which city is polaris highest in the sky?
the north pole, but the closest city would be around the arctic circle, you'll have to find that on your own.
