The unit used is usually the Astronomical Unit (AU), which is the average distance from the earth to the sun, and is approx 150 million km.

How can astronomers tell whether there is a second unseen star in a system?
Because of perturbations within the observed star.
How do astronomers label some stars within constellations?
Astronomers label the stars within constellations according to apparent magnitude.
What is the most useful unit for measuring distances within the solar system?

What is the basic unit of distance within the solar system?
AU - Astronomical Unit, but miles and kilometers are used for distances
Light Year and when do use an Astronomical Unit?
Use "Astronomical UNit" or AU when discussing distances within the solar system. Use "light year" when talking about the distances between stars.
What do you use to measure the distance to far away stars?
Light years, parsecs, and kiloparsecs. Light years and parsecs are used to measure distances between neighbouring star system's, kiloparsecs are used to measure distances within a galaxy.
What is Measure of distance in space?
A "light year" is probably the best known measure. That's how far light travels through space in a year. Professional astronomers also use a measure called a "parsec". Of course, for relatively small distances miles and kilometers are used. Another unit used within our solar system is the astronomical unit (AU), which is equal to the average distance between Earth and the sun (about 93 million miles or about 150 gigameters).
What is used to describe distances within the solar system?
light years
Why do astronomers use light-years to measure distance in space?
Astronomers use light-years (ly) to measure distances in space because space is simply so large. Light travels very fast, so it can easily be used to measure distances without resorting to large scientific notation numbers. Inside the solar system, they use the astronomical unit or AU. It is The distance from the Earth to the sun or 93 million miles. Simply put: D. The distances are too great to measure in Earth units. For example, 1 AU = 149,598,000 kilometers = 92,955,887.6 miles 1 ly = 9.4605284 × 1012 kilometers = 5.87849981 × 1012 miles
Why was the term light year in invented?
Distances to other planets, other stars and other galaxies are very large, making measurements in meters or kilometers difficult to handle (although scientific notation can be used). As a result, astronomers have gotten accustomed to measure distance within the Solar System in astronomical units, and to other stars and galaxies, either in light-years or in parsecs.
How can astronomers tell whether there is a unseen second star In a system?
Because of perturbations within the observed star.

Do distances within the solar system have to be measured by light-years?
Any distance can be measured by any unit. It doesn't make a lot of sense to measure distances in light years, when it only takes light a few hours to make the journey within our solar system. Light goes from the Sun to Pluto in about 5.5 hours. Which is 0.00062 years, the assoicated distance being 0.00062 light years.
Are kilometers the most useful unit of measure when discussing objects in our solar sysytem?
You can use kilometers if you like. On the other hand, distances within the Solar System are often quoted in AU (astronomical units), where 1 astronomical unit is the distance from Sun to Earth. Such distances are easier to visualize.
