For small distances, e.g. Earth to Moon, scientists use miles of kilometers. For larger distances, e.g. the orbit diameter of Jupiter, they use the "AU" or Astronomical Unit, which is the distance from the Sun to Earth. For enormous distances, astronomers use the lightyear, which, although it sounds like a time unit, is truly a distance unit. A lightyear is the distance light travels in one year, or 5.87849981 × 1012 miles. Another unit for large distances is the Parsec, which is 3.26 lightyears.

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.
How do astronomers rate the magnitude of a stars?
Many astronomers use a common method known as terenateral. This is when they record the height of the corona on the star and use a unit of measurment known as hypengeroly.
Why do astronomers depend on technology?
Back in the older times astronomers didn't have our current instruments, but as time went on technology advanced and made it easier for astronomers to do what they do. But to answer your question astronomers depend on Technology because they want accurate observations and plus like i said earlier it is easier to use technology.
What conclusion do astronomers make based on the red shift?
use your brain to answer it its ok for your answer.
How is a parallax helpful to astronomers?
Parallax is the apparent change in postion of an object when looked at from two different places. Astronomers use parallax to find how far away nearby stars are.
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 used to find a planet's distance from the sun?
When exploring space, astronomers use astronomical units, (AU) to measure the distance from one object to another. Since every distance from one object in our solar system to another object in our solar system, the distance of a planet from the sun would be measured in astronomical units
What do astronomer usually measure distance to stars with what units?
Light years. Strictly speaking, professional astronomers use "parsecs". However they also use light years, which are better known to most people.
What is used to measure space?
Units of volume are. For big distances, astronomers use "light years" and "parsecs". A light year is the distance that light travels through space in one year.
How do astronomers measure the distance of planet?
They use complicated trigonometry and mathematics.
How do astronomers use trigonometry?
One example of an astronomer's use of trigonometry is determining the distance to a star by triangulation.
What is the unit that astronomers use to measure the differences between stars and other galaxies?
They do not use units: they use the fact that stars are not galaxies. For example, you don't use units to measure the difference between children and countries.
How far is 31.95 astronomical units?
The distance from the Sun to the Earth is 93,000,000 miles. When discussing distances within the solar system, it is often convenient to use this distance as a comparison. So astronomers use the distance from the Sun to the Earth as 1 "Astronomical Unit", or AU. So 31.95 AU is 31.95 times 93,000,000 miles, or a little more than the distance from the Sun to the planet Neptune.
What do astronomers use to measure distance to stars?
If you refer to the units, both the light-year and the parsec are often used. A light-year is the distance light travels in a year; about 9.5 x 1012 kilometers (9.5 million million kilometers). A parsec is about 3.26 light-years.
What unit of distance do astronomers use to measure distances to stars?
Usually light-years, or parsecs.
What metric units do you use to measure distance?
Miles.
What unit do astronomers usually use to measure the distance to a star?
They use light years, the distance light can travel in 1 year. It's equivalent to 5878499810000 miles.
