Define light year and explain its value in astronomy?
A light-year is the distance light travels in a year - equivalent to almos 10 million million (or 1013) kilometers. In popular astronomy, distances to stars or galaxies are often stated in light-years; although astronomers often prefer another measure, the parsec, equivalent to about 3.26 light-years.A light-year is the distance light travels in a year - equivalent to almos 10 million million (or 1013) kilometers.

What unit do astronomers usually use to measure distances in the solar system and how is it abbreviated?
Distances within the solar system are usually reported in kilometers or AUs.1 AU = average distance of Earth from the Sun, about 150 million kilometers (149,597,871 km).Nearby . . . miles or kilometersOut past that . . .

What year was the first ruler made?
devices for measuring distances have been around for almost as long as the human race has existed.
How many human years are in a cats life?
wonder how many years are in one human year it is...7 and there you have it that's your answer 7 is dogs. around 9 to 15 but it depends on the breed.
What biome is hot and humid all year long?
Your mom is hot and humid all year long.
What is the order of increasing length of astronomical unit parsec kilometer and light year?
kilometer, AU (astronomical unit), light year, parsec.
How many light year in parsec?
1 Parsec = 3.26163626 light years
What is light year A parsec?
"Light-year" and "parsec" are two units of length used in astronomy - for distant objects. 1 parsec = 3.26 light-years. A light-year is defined as the distance that light travels in a year. A parsec is defined as the distance at which an object would have to be to have a parallax of one arc-second.
What is a light parsec?
"Light-year" and "parsec" are two units of length used in Astronomy - for distant objects. 1 parsec = 3.26 light-years. A light-year is defined as the distance that light travels in a year. A parsec is defined as the distance at which an object would have to be to have a parallax of one arc-second.
What are the distances represented by a light year an astronomical unit and parsec?
A light year is the distance that light will travel in one year. A parsec is short for parallax second, which is also a measure of distance.Answer 1 Parsec = 3.26163626 light years 1 light year = 0.30659458 Parsecs
How many parsec make up a light year?
It's the other way around - how many light yearsmake up a parsec? The answer is: 3.26 light years make up one parsec.
What are the conversions of a light year?
There are three and a quarter light years in a parsec.
What units express stellar distances?
Light-year, or Parsec.
How to convert km per seconds to parsec per year?
To convert km per second to parsec per year, you can use the following formula: 1 kilometer per second is approximately equal to 1.042x10^-13 parsecs per year. So, to convert, you multiply the value in km/s by this conversion factor to obtain the value in parsecs per year.
When is a parsec used?
Parsecs are used as units of measurement for the enormous distances in space. One parsec is roughly 3.3 times greater in distance than one light year. A light year is the distance light travels in one year in a vacuum.
Which unit of measurement represents the distance light travels in one year light-year or parsec?
"light-year"
One parsec is equivalent to how many trillion miles?
No. The distance light travels in a year is called a light-year. A parsec is the distance at which a star (or other object) would have a yearly parallax of 1 arc-second, and it is equal to about 3.26 light-years.
