The distance to nearby stars can be measured by using?
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.
What is used to determine the distance to nearby stars?
They use trigonometry to determine the distance to nearby stars. They measure the star's positions at one point in time, and again six months later, calibrating against the backdrop of the far distant stars. The nearby stars will show a parallax shift in position, so they calculate a triangle, with the Earth at two points, and the base 186 million miles long. The star is the third point on the triangle, and it is simple trigonometry from there to figure out the distance.
What is one way scientist use to calculate the age of the universe?
Measure the distance from Earth to nearby stars.
Why must a star's parallax be known before you can find the luminosity?
What must be known is the distance. And the most accurate method to measure the distance of nearby stars is the parallax - but this method won't work for stars that are far away.
What can distances to nearby stars determined by?
Stellar parallax
What are the steps when examining distance determination?
The answer depends on what distance is being determined: the distance to stars using parallax, the distance to aircraft using radar, the distance from one city to another partway around the earth, the distance between two nearby objects.

What ways can you measure th distance to nearby stars?
You can measure it by using absolute magnitude.

Can the distances to nearby stars be measured by color?
That is one of the things scientists use to help them measure a stars distance but it isn't just based on the color.

How do astonomers measure the distance to nearby stars?
Astronomers use the unit of measure "Light Years" to calculate the distance between pretty much anything in the Universe.
