### What is the apparent movement of a star used to measure its distance from earth?

This is called PARALLAX.

### Apparent movement of a star used to measure its distance from earth?

The absolute magnitude of a star is the amount of light received by earth?

### Is parallax a star?

The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).

### What measures star distance from the Earth?

Stellar Parallax Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. Simply put, they measure a star's apparent movement against the background of more distant stars as Earth revolves around the sun.

### What is a stars brightness as if it were a standard distance?

Theres `Absolute Magnitude` which is the brightness of a star at a set distance. Then there is `Apparent Magnitude` which is the apparent brightness from earth, regardless of distance.

### Which earth motion causes the apparent daily movement of the constellations?

The rotation of the earth around its axis.

### What does apparent magnitude depend upon?

apparent magnitude (brightness of a star when viewed from Earth) depends on the size of the star, how hot it is, and its distance from Earth

### How are absolute magnitude and apparent magnitude alike?

Absolute magnitude and apparent magnitude are the same because they are both ways on how to measure the brightness of a star. Absolute magnitude is how bright is the star if we will see it in a 32.616 light-years distance while apparent magnitude is the brightness of it that we see on Earth.

### What was the solution to the sun moving with or against people?

Not sure what you mean; the Sun has an apparent daily movement from east to west. Actually this apparent movement is caused mainly by Earth's rotation.

### What is used when astronomers measure the distance from the sun to the earth?

Parallax is the method that astronomers use to measure the distance from the sun to the earth.

### What is apparent movement of sun?

It appears to move from east to west because of the earth's rotation.

### Why does the ecliptic show?

The ecliptic is the apparent path of the sun's movement in space, as viewed from the earth.
