What is the difference between a light year and a year?
A light year is actually a measure of distance. it's the distance that light travels in one earth-year. A year is a measurement of time equal to the amount of time that it takes the earth to go around the sun once.
How do astronomers measure light years in space?
Astronomers measure light years in space by calculating the distance that light travels in one year. They use the speed of light, which is about 186,282 miles per second, to determine how far light can travel in a year. This distance is equivalent to one light year. By observing the time it takes for light to reach Earth from distant objects in space, astronomers can estimate their distance in light years.
What do light years measure in astronomy?
Light years measure distance in astronomy. It is the distance that light travels in one year, which is about 9.46 trillion kilometers.
How much time would pass on Earth if I traveled at the speed of light for a year?
If you were to travel at the speed of light for a year, no time would pass for you, but approximately one year would pass on Earth.
What does a light year measure in terms of distance?
A light year measures the distance that light travels in one year, which is about 5.88 trillion miles or 9.46 trillion kilometers.
What is the speed of light year kilometer per hour?
"Light-year" is not a speed, it is a distance - the distance light travels in a year.The speed of light is 300,000 kilometers per second. If you multiply that by 3600 (seconds/hour), you get the speed in km/hour.
Who is the scientist use the light year to measure the speed of light?
It doesn't work that way. The light-year is not used to measure the speed of light. It works the other way round: First, the speed of light is determined through other methods, then the distance called a light-year is calculated based on that measurements.
How many kilometers in one lightyear per hour?
A light year is the distance that light will travel in a vacuum in a year. Nothing can travel that distance in an hour so a lightyear per hour is a meaningless concept of speed. Though impossible to attain, it is a measure of speed while a kilometre is a measure of distance. There is no direct relationship between the two.
What is use by scientist to measure the distance light travel in one year?
Scientists don't measure the distance light travels in one year. They calculate it by measuring the speed of light. The speed is 300,000,000 meters/sec. and can be measured in the laboratory with a rotating mirror apparatus. To get the distance traveled by light in one year you multiply the speed (above) by the number of seconds in a year. The answer will come out in meters and is also called one light year.
How fair does light travel through space in 1 hour?
1 light hour like how a light year is how far light travels in a year.
What is the speed of a light year?
# The distance that light travels in a vacuum in one year, approximately 9.46 trillion (9.46 × 1012) kilometers or 5.88 trillion (5.88 × 1012) miles.
What is light year and what speed does light travel?
A "Light Year" is a measure of distance. It equals approximately 9.5 trillion kilometers or 5.9 trillion miles. The Speed of Light (C) is: 299,792,458 meters per second 17,987,547,480 meters per minute 1,079,252,848,800 meters per hour 186,282 miles per second (~ 71/2 times around the Earth in one second) 11,176,920 miles per minute 670,615,200 miles per hour
How long would it take to go one light year?
Depends on your speed. A light year is the distance light travels in a year. If you traveled slower it would take longer.Depends on the speed you are going.At the speed of light one year.See related question for details of a light yearJust like any other distance, it depends on the speed of travel.-- At the speed of light, radio, x-rays, etc., it takes 1 year.-- At 1 million miles per hour, it takes about 671 years.-- At 60 miles per hour, it takes about 11.2 million years.A light year is the distance that light will travel in one year in a vacuum. The speed of light is 186,000 miles per second. So, light will travel about 5.8 trillion miles in one year. Now, to answer the question. The answer depends on how fast you are traveling. If you were in a space ship travelling 99.9999% the speed of light, it would take you about a year to travel a light year. Now, there is currently no human-made space craft, that we know of, that can travel that fast. The space shuttle travels at about 17,500 miles per hour. In order for the space shuttle to travel one light year, it would take about 38,262 years.
What is the difference between a light year and a year?
A light year is actually a measure of distance. it's the distance that light travels in one earth-year. A year is a measurement of time equal to the amount of time that it takes the earth to go around the sun once.
When do light years become greater?
A light year is the distance covered by light in a year. So a light year is greatest when the speed of light is greatest: that is, in vacuum. However, since much of outer space is near vacuum, a light year is near enough a constant measure.
Are light years a measure of distanse or time?
Light years is actually a measure of distance expressed in time. For example, a galaxy is 1 light year long, which means it will take 1 year to reach that galaxy with the speed of light(c). This implies that the galaxy is c(m/year)*1 meters long.
Speed of light in miles per hour?
We don't know what "hour second" means, and have a nagging suspicion that it's quite meaningless. In vacuum, the speed of light is roughly -- 186,282 miles per second -- 670,615,200 miles per hour -- 16,094,764,800 miles per day -- 112,663,353,600 miles per week -- 5,878,715,206,000 miles per year.
