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.
The apparent westward movement of a planet is known as?
retrograde motion
What is the apparent backward motion of a planet seen from earth called?
That is called 'apparent retrograde motion'.See the related link listed belowfor more information.
What happens during the apparent retrogate motion of a planet?
When that happens, the planet moves from east to west, from our point of view. This should not be confused with the daily motion of all stars + planets due to Earth's rotation; rather, to the planet's movement against the background of the stars.
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).
In what direction is the apparent daily motion of the sun?
It is westwards.
Which earth motion causes the apparent daily movement of the constellations?
The rotation of the earth around its axis.
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.)
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.
What is a star's apparent shift in motion called?
Motion parallax.
What is Mercury's apparent motion?
mercurys motion can be like any other planets motion
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 are two types of star motions?
Actual motion and apparent motion.
How does apparent force affect the motion of an object?
Accelerates the motion of an object.
What is a stars apparent shift in position?
Motion
The apparent westward movement of a planet is known as?
retrograde motion
What is the apparent backward motion of a planet seen from earth called?
That is called 'apparent retrograde motion'.See the related link listed belowfor more information.
