What is The apparent change in position of an object with respect with respect to a distant background is called?
Parallax id the apparent shift in position of an object with respect to the background due to a shift in view point.
The planet that moves through the background of stars most slowly is?
The planet that moves through the background of stars most slowly is Mercury. This is because Mercury is the closest planet to the Sun and has a shorter orbit period than the other planets, resulting in a slower apparent motion against the background of stars as seen from Earth.
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".
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 is a stars level of brightness as viewed by the unaided eye called?
Apparent magnitude.

What is the unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is the standard unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
How do you distinguish between a star and a planet?
Stars in the night sky appear fixed, since they are much further away than planets. The planets can be identified through their apparent brightness and their movement among the background stars over time.
What is an instrument for simulating the apparent motions of the sun moon and other celestial bodies against a background of stars?
Solar System models, especially mechanical models are called orreries.
What is the background song for summer of stars Disney?
its called summer of stars.
