The distance light travels in one year is called a light year.
It is approximately 6 trillion miles.
9.4605284 x 1015 metres
Light year is the distance traveled by light in one year. we just cannot imagine this. Because light travels 3*108 m/s. so just think how much it will travel in one minute, one day, one week, one month & one year.
Exactly 9,460,730,472,580.8 (just under 9.46*1012) kilometers.

What term is used to describe the actual amount of light given off by a star at a standard distance?
The term used to describe the actual amount of light given off by a star at a standard distance is "absolute magnitude." This measurement helps astronomers compare the true brightness of stars by standardizing it for a set distance of 32.6 light-years.
Why do astronomers say that looking at constellations is looking into the past?
Because of the speed of light. A light year is a term of measurement of distance, not time - i.e. the distance that light can travel in one year. Light travels at 299,792,458 metres per second - almost 3 million kilometres a second - therefore in one year it would travel a collosal distance - near 94 million million kilometres. When astronomers say a planet is 400,000 light years away, what we see of this planet happened 400,000 years ago since the light is only reaching us now. It would be another 400,000 years before we see that planet as it is today.
What is earths distance from gamma?
Gamma is a general term that typically refers to electromagnetic radiation produced during radioactive decay. It is not a specific entity or location, so it does not have a defined distance from Earth.
Can light travel in outer space?
A good question. Light can not exactly move an object into space but once an object is in space the light from the sun can be used to move it, and I don't mean solar panels harnessing electricity. A probe can actually have a "sail" like panel protruting from it that can harness radiation being given off by the sun and use it like a sail boat does to harness energy for movement. You might have heard the term solar wind which is basically the same idea. Believe it or not, space probes and other vehicals can obtain pretty fast speeds just by using solar wind. Hope this information was helpful.
When was the light year discovered?
what is the name of make electricity? =========================== The light-year was not 'discovered'. It's a definition that was 'invented' when scientists began to work with distances that were too great to be described with the units of length that were previously available. For example, when the distance to the nearest star was measured, a paper had to be published to report the finding, but it would have been pretty awkward to report that the nearest star is about 24,635,900,000,000 miles from us. The 'light-year' was adopted in order to discuss 'astronomical' distances, being the distance that light will travel in a year. Using this unit, the nearest star is about 4.2 light-years from us, which is a lot easier to talk about. Today, scientists are routinely observing things that are billions of light-years distant from us, and the light-year itself is becoming too small and inconvenient, and other, larger units have been defined. Like the 'Parsec', which is about 32 light-years, or about 188,300,000,000,000 miles. And the 'Megaparsec', which is a million parsecs, or about 32 million light-years, or about 188,300,000,000,000,000,000 miles. You get the idea.
What term indicate through which light does not really travel?
A vacuum is the term that indicates through which light does not really travel.
What is the term for the distance light can travel in a billionth of a second?
Light second
What does astronomical term LY mean?
LY stands for light year, which is a unit of distance in astronomy. It represents the distance that light travels in one year in a vacuum, approximately 9.461 trillion kilometers. It is commonly used to describe vast distances in the universe.
What term is used to describe the collection that includes gamma rays x-rays ultraviolet light visible light infrared radiation and radio waves?
All travel at the same speed through a vacuum
What is the astonomical term for the distance light travels in a year?
A light year.
Which these is a term for measuring distance in space?
light-year(:
What is the term that describes a wave that does not need a medium I am order to travels?
The term is "electromagnetic wave." These waves can travel through a vacuum because they consist of oscillating electric and magnetic fields, and do not require a medium for propagation. Examples include light waves and radio waves.
What kind of wave is light considered?
Light a general term for a specific range of wavelengths in the electromagnetic spectrum, is not strictly just a wave, it shows particle and wave like properties, hence it being able to travel in a vacuum without a medium. However as a wave light is considered to be a transverse wave.
How many years are in 25000 light years?
Light years is a term that actually measures distance.
How does the speed of visible light compare with the speed of gamma ray?
Both visible light and gamma rays travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (or about 186,282 miles per second). Thus, there is no difference in the speed at which visible light and gamma rays travel.
What is the term for an image through which light does not really travel?
The term for an image through which light does not really travel is "virtual image." These images are formed by the apparent intersection of light rays that appear to come from a point behind a mirror or lens, but do not actually pass through.
How fast is a sunlight?
In general light travels at an incredible speed ie 300,000 km per second. This is the speed of light in vacuum and in denser medium it will be a little bit reduced. In glass medium it will become 200,000 km per second. Any way in between sun and the earth the major part of the distance between them will be vacuum and the remaining is occupied by less dense air. So the speed of sun's light would be the same as 300,000 km per second. The amount of time it takes for sunlight to travel from the sun to earth is 8 minutes hense the term faster than the speed of light Sorry friend, it does not mean that light travels at faster rate. The distance between the earth and sun will be that quantity which would be covered in 500 seconds by the light with speed of 300,000 km per second.
