Why is the unit light year invented?

A light-year is a unit of distance, not a unit of time.

Light year is a unit of distance. It is the distance light travels in a year.

A light-year is a unit of length, or distance. It is the distance light travels in a year. (People sometimes confuse this, believing a light-year to be a unit of time.) A light-year is approximately 9.5 trillion kilometers.

The answer is Distance. A light-year is a unit of distance.

A light-year is a unit of distance. It is not a unit of time. 365 light days, unless it is a light leap year.

A light year is a unit of distance, It is the Distance Which light will Travel in an year This is the largest unit of Distance. 1 light year = 9.4605284 × 1015 meters !!

False the light year is not a unit of time it is a unit of distance true.

A light year is not a unit of time, it is a unit of distance. It is the distance light travels in one year in a vacuum.

A light-year is a unit of DISTANCE, not a unit of TIME. A light-year is the DISTANCE travelled by light in one year.

A light year is larger than an astronomical unit.

No. One light year is about 63,200 AU. An astronomical unit is about 8 light-minutes.

"Light-year" is a unit of distance. It's the distance that light travels through vacuum in one year. Roughly 5,878,700,000,000 miles.

This is impossible to answer: a month is a unit of time. A light year is a unit of distance. There is no conversion.

"Light-year" is NOT a unit of time. It is a unit of length or distance - the distance light travels in a year.

This is an impossible conversion to make. A hour is a unit of time. A light year is a unit of distance, specifically, it is the distance light travels in a year.

A light year is bigger

The "light year" is a unit of distance defined as the distance that light travels through vacuum in one year. The "astronomical unit" is a unit of distance defined in terms of the Earth's distance from the Sun. One light-year is equivalent to roughly 63 thousand astronomical units.

It doesn't make sense to convert that. A light-year is a unit of distance, not a unit of time. A light-year is the distance light travels in a year.

One Light-year is 63,024 Astronomical units.

A light year is about 63,000 times greater than an astronomical unit.

The unit of measurement is the "light year".

A light year is a unit of length equal to just under 10 trillion kilometres.

An astronomical unit is not larger than a light year. A light years is considered to be approximately 62,000 times larger than an astronomical unit.

The light-year is the distance light travels in a year. Since this sometimes causes confusion, please note that a light-year is a unit of distance; NOT a unit of time. A light-year is approximately 9.5 x 1012 kilometers. (A light-year is defined to be exactly 9,460,730,472,580,800 metres.)

No. A light year is a unit of distance, not time. It is the distance light travels in a year.

This may give you some idea how much longer a light year is than an Astronomical Unit: 1 AU = about 500 light seconds.

A light year is the distance light travels in one year. Note that it is a unit of DISTANCE

The distance light travels in one year is called a light-year. To get the number 9,470,000,000,000, the unit used is the kilometer.

Joseph Swan invented light bulb in 1879

A light-year is a unit of distance - the distance travelled by light in a year. Light travels 300,000 km in a second, so a light-year is about 9.5 x 1012 (9.5 million million) kilometers.

A light-year is not a unit of time. It is a unit of distance - the distance light travels in a year, about 9.5 x 1012 km.

Because in space things could go on for miles and miles, and it would be to big of a number. A light year is specifically how much light goes in a year, and light is fast. Making a long distance and you don't read a humungoes number even if it was estimated it would be 6.35 times 10 to the power of 300!

Both contain the word "year," but are otherwise unrelated. A light year is a unit of distance, while a leap year is a correction to a unit of time.

At 150000 miles per hour, it would take 39.2 million years to travel one light year.

kilometer, AU (astronomical unit), light year, parsec.

"light-year"

A light-year. One astronomical unit is the distance Earth-Sun; it takes light a bit more than 8 minutes to travel that distance. A light-year, of course, is the distance light travels in a year.

A light year is a unit of measure for distance - the distance light can travel in one year in vacuum.

The distance that light travels in one year

A light year.

a light year is a unit of length, not velocity.

A light-year is a unit of distance, not a unit of time.

The light bulb was invented by Thomas Alva Edison in 1879.

Fundamental unit all examples

A light year is much larger. 1 light year = 63,240 Astronomical Units

A light year is the distance that light (travelling at approximately 300,000 km/second in a vacuum) goes in one year. It's about 9.46 trillion kilometers. The light year is a convenient unit for distance in outer space because stars are extremely far apart in relation to any measurement on our planet. For example, the nearest star other than our sun is about 4.34 light years, or about 41,000,000,000,000 kilometers. It is important to remember that…

yes it is distance

Light year is a unit of distance not of velocity.

The astronomical unit is the average distance from the earth to the sun, and is 149 598 000 kilometres. A light year is the distance light will travel in a year, the speed of light is just under 300 000 kilometres per second, so light travels one astronomical unit in just over eight minutes. A light year is 9.46x1012 kilometres, or 63239.67 astronomical units.

A light year is a unit of measure applied to the great distances between objects in space. A light year is the distance that light travels in one year (in a vacuum).
