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.

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 a stars apparent shift in position?
Motion
The apparent motion of stars is due to movement of?
The rotation of the Earth makes the stars appear to move in the sky.
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).
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
How does a geocentric model explain the apparent motion of the stars?
All the stars are fixed to a sphere, which rotates once in 24 hours.
What is stellar motion?
the actual movement of the stars through the backdrop of other stars is one answer
Why do modern astronomers continue to use the celestial sphere when they know that stars are not all at the same distance?
For some purposes, especially explaining the apparent motion of the stars, the actual distances are not relevant, so the celestial sphere is still a useful model in such cases.
When does a planet is said to be in retrograde motion?
A planet is said to be in retrograde motion when its apparent motion - the motion as seen by us, against the background stars - is from east to west.Planets spend more time in prograde motion, from west to east. The apparent movement of Sun and Moon against the background stars is also from west to east. Not to be confused with the daily motion, due to Earth's rotation.
The apparent shift in the position of nearby stars when compared to distant stars is?
Doug Fany answer: Parallax
If two stars have the same apparent magnitude are they the same distance from Earth?
No. Brighter distant stars can have the same apparent magnitude as fainter stars that are closer.(Absolute magnitude does not refer to actual brightness, but rather to what the brightness of a star would likely be at an arbitrary distance of 10 parsecs, rather than its actual distance.)
