they appear blue due to the flame
Stars and constellations appear to move in the night sky because the Earth is rotating, while the stars and constellations stay there.
because those stars have high luminosities.
The color of a star comes from its temperature. The coolest stars appear red, while the hottest stars are blue. And for a star, the only thing that defines the temperature of a star is its mass. Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it's going to appear blue to our eyes. An example of a blue star is the familiar Rigel, the brightest star in the constellation Orion and the 6th brightest star in the sky. Astronomers calculate that Rigel is approximately 700 and 900 light-years away, and yet it appears almost as bright as a star like Sirius which is only 8.3 light-years away. The temperature of Rigel is approximately 11,000 Kelvin; it's this high temperature that accounts for Rigel's color. Rigel puts out about 40,000 times the energy of the Sun.
When the sun sets, you can watch the sky as the stars and moon appear.
because of earths rotation
blue or white
Stars in the sky appear at night time. If it is cloudy outside, stars will not be able to be seen by the naked eye. The moon also appears at night time.

Stars appear different from the sun because the sun is closer to the earth and the other stars are further away from the earth so that's why the appear differently when you look at them in the sky!!!!!
