What does rising and setting of stars mean?
The rising and setting points of celestial bodies (sun, moon, stars, and planets) are determined by their positions on the celestial sphere. The sphere appears to be rotating from east to west every twenty-four hours, so celestial bodies appear to rise in the east and set in the west.
What do you call the rising and setting of the sun?

Between the equator and the poles … you’ll see some circumpolar stars and some stars that rise and set daily.
What is meant by diurnal motion?
Diurnal motion, apparent daily motion of the heavens from east to west in which celestial objects seem to rise and set, a phenomenon that results from the Earth’s rotation from west to east. The axis of this apparent motion coincides with the Earth’s axis of rotation.
What is Acronychal rising?

They are now called, respectively, declination and right ascension. Directly out from the Earth’s equator, 0° latitude, is the celestial equator, 0° declination.
Why do we say sunrise and sunset?
We can’t say that the Earth is moving (It’s not like saying Earth is not round :p). For us Earthlings, Sun is moving and going from east to west everyday just to make you enjoy a romantic eve with your better half seeing the sunset. (See how good the sun is 🙂 ). So that’s why we say it’s SUNSET and SUNRISE.
Why is the rising sun red?
During sunrise and sunset the sun is low in the sky, and it transmits light through the thickest part of the atmosphere. We see the red, because red wavelengths (the longest in the color spectrum) are breaking through the atmosphere. The shorter wavelengths, such as blue, are scattered and broken up.
Where do stars set?
As Earth spins, the stars appear to move across our night sky from east to west, for the same reason that our Sun appears to “rise” in the east and “set” in the west. Stars close to the celestial poles, the imaginary points where Earth’s north and south axes point in space, have a very small circle of spin.
What color represents the hottest star?
The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K. Stars are fuelled by the nuclear fusion reactions at their core.
