Because you are looking through several miles of atmosphere and the air currents cause the stars to twinkle.
That is the result of atmospheric turbulence.
Earth's movement around the sun bends the light.
Earth's movement around the sun bends the light.
Stars are not twinkling really. It is because of the atmosphere of the earth due to which they appear twinkling. However if they are seen from above the atmosphere of earth then they appear stationary.
Both twinkle - even the sun does. However the relative size, as seen from Earth, means that the amount of "twinkle" is far more apparent for a star than for a planet. there is an apparent change in position of stars , so they seem to twinkle
No. Stars twinkle on Earth because the light beams have to enter the atmosphere, altering the brightness of the star by the second. Since the moon really doesn't have a atmosphere, stars seen from there wouldn't twinkle.
Because the sun is closer to earth than other stars
No. A constellation is a group of stars that appear to be in a pattern as seen from Earth. The sun is just one star.
Because it is the closest star to the earth and it can be seen so easily.
That`s because of small disturbances in the earths atmosphere. Planets don`t twinkle because their light is stronger, whereas the light of stars is weak enough to have their light slightly bent by the moving atmosphere.
The light emited by stars can take thousands of years to reach the Earth, because the stars can be located thousands of light years away. Stars viewed from Earth can only be seen at night because the light from the sun creates a glear on the atmosphere.
a stars brightness as seen from Earth
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.
