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".

How do astronomers measure the distance to nearby stars?
Astronomers use a method called parallax to measure the distance to nearby stars. Astronomers can measure parallax by measuring the position of a nearby star with respect to the distant stars behind it. Then, they measure the same stars again six months later when the Earth is on the opposite side of its orbit.
Does the position of earth and the moon cause Moon's phase?
No, the position of the Moon and the Sun as OBSERVED from the Earth.
Does the constellation observed from the northeastern US differ from the constellation observed when earth is position C because the earth moves in its orbit?
Yes
How do astronomers measure the distance to stars that are less than 1000 light-years from the earth?
Because the angle of shift is very small and extremely difficult to measure, scientists usually use photography to measure the shift. The star is photographed at the beginning and end of a six-month period, and its position in relation to other stars is studied each time.
Why do astronomers use Declination and Right Ascension?
These are coordinates that define the position of an object in the sky (on the "celestial sphere"). They are used in a similar way to how latitude and longitude are used, on the Earth's surface.
How do astronomers create three dimensional maps of the universe?
by using the position on the sky and the redshift to determine a distance along the line of sight

How does the micros cope change the position of the object being observed?
by changing the position of the object being observed
Is motion observed from stationary or relative positions?
motion can be observed from any position
Can you determine earth s position?
No , I can't , it is job of astrologist and astronomers !
The distance between the final position and the starting position is the?

Does the position of earth and the moon cause Moon's phase?
No, the position of the Moon and the Sun as OBSERVED from the Earth.
What is his position at 1 second if distance 2 is -1 and distance 1 is -4?
Distance 1 is -4 so the position is -4!
Does the constellation observed from the northeastern US differ from the constellation observed when earth is position C because the earth moves in its orbit?
Yes
What does a stage do in the microscope?
Supports the specimen to be observed in the correct position in the light path.
How is maths used in astronomy through simple method?
Kepler used math to show that the orbits of planets were ellipses, that the period of revolution was proportional to distance, that areas swept out during equal time intervals were equal. Astronomers use math to calculate distance to stars, predict the position of stars in the sky from one year to the next.
