What is a stars apparent shift in position?
Motion
What is a stars shift in position called?
Motion
The apparent shift in the position of nearby stars when compared to distant stars is?
Doug Fany answer: Parallax
Why there are seasons and the apparent motion of the stars and sun?
The seasons are due to axial tilts of planets and the apparent motion of stars and sun on the celestial sphere is due to diurnal motion.
What is the apparent shift of stars as earth orbits the sun?
parallax :)
Compare the apparent motion of star to the actual motion of stars?
The actual motion of stars is very hard to see because stars are very far away.
The apparent motion of stars is due to movement of?
The rotation of the Earth makes the stars appear to move in the sky.
When esimating the distance of the stars from earth astronomers use the fact that nearby stars shift in position as observed from earth which is called?
Nearby stars appear to change their position against the distant background in an annual cycle, because of the Earth's changing position 'across' its orbit. This apparent shift is called the star's "parallax".
In what direction is the sun's annual motion relative to the fixed stars?
The Sun's apparent motion among the stars is from West to East - just like the motion of the Moon, and the predominant motion of the planets (planets sometimes go from East to West, too - in this case they are said to be retrograde).
The apparent westward movement of a planet against the background of stars is called?
"Parallax shift". We can't SEE the difference in position of any star as seen from the Earth 6 months later or earlier, but by measuring the very tiny differences in the positions of the more distant stars, we can observe the "parallax" of a star and thus calculate its distance. This only works for stars less than about 300 light years from Earth.
What causes the apparant movement of stars in the sky?
The real motion of stars is hardly noticeable even over a period of many years. It's the Earth's daily rotation the is the main cause of their apparent motion. (Stars are so far away that the Earth's revolution around the Sun hardly cases any apparent motion.)
The apparent westward drift of the planet compared to the background stars is occultation?
no its retrograde motion
