1 500 million kilometers a few light years 5

A light-year is a unit of length that is generally used in astronomy. 1 light year represents the distance traveled by light in a vacuum for 1 year (365 days).

1 light year, 365 days, 24 hours, 60 minutes, 60 seconds, 299792458 meters, 9,454.3 billion kilometers.

Thus, 100 million kilometers light years. In astronomy, 100 million kilometers represents the average distance between the Sun and the Earth, so astronomy records 100 million kilometers as 1 astronomical unit. It is more appropriate to use astronomical units within the solar system.

And at larger scales, such as the Milky Way, people use light-years to express it. Of course, there is also a larger unit of scale, the parsec. 1 parsec = light year = 206265 astronomical unit = 308568 billion kilometers.

Light is 300,000 kilometers per second.

A light-year is about a trillion kilometers, and 100 million kilometers is equal to.

It's about light years.

Light, walking about 300,000 kilometers per second, 100 million kilometers of light only need to walk 500 seconds, that is, 8 minutes and 20 seconds, and the year is too far away, so this "small" distance, you still don't need light years! It seems that there is no such thing as a "light second", if there is a unit, it is 500 light seconds!

1 light year is the distance that light travels in a year, light, about 300,000 kilometers per second, every year = seconds, then 1 light year = kilometers, and the rest will be calculated by yourself.

One light-year equals trillions of kilometers.

One light-year is 9,460'7304'7258'0800 meters, which is equivalent to a trillion kilometers. Therefore, a light year is equal to the multiplication of time and the speed of light, the speed of light is 299792458m s, and there are 31,536,000 seconds in a year.

Light-years are generally used to measure the distance before a celestial body, for example, we will say that the distance between the solar system and Proxima Centauri is 100 million light-years, because the distance in the universe is too far to be measured in the units of the earth, so a larger unit needs to be invented. As the name suggests, light-year means that light can travel a year's distance in a straight line in the universe.

Light-year development history:

Ole Romer was a Danish astronomer whose greatest achievement in his life was the discovery of the speed of light. While working at the Paris Observatory in France, he discovered four moons of Jupiter, and then he tried to calculate the orbital period of Europa. It could be calculated based on the degree of occultation between Europa and Jupiter, but he was surprised to find that the results were different for each measurement, and there was a time difference in between.

After thinking about it, he realized that the reason for this difference was that the movement of light takes time. So he measured the speed of light, but the error was still relatively large.

1 light-year (ly) = 9460730472581 kilometers (km), which is a trillion kilometers.

So 100 million billion kilometers is 10,000 trillion kilometers, which is about 1,057 light years.

A light-year, a unit of length, is generally used to measure the distance between celestial bodies, literally 9,460'7304'7258'0800 meters in a straight line in a cosmic vacuum. Because the astronomical data is so large, larger units are needed for a rough description.

100 million kilometres is equivalent to about 1057 light years.

100 million billion kilometers = 1000000000 * 100000000 kilometers. One light-year is equal to 9460730472580800 meters, which is approximately equal to kilometers, so 100 million billion kilometers = 100,000,000,000 * 10,000,000,000 kilometers kilometers = 1,057 light years.

One light-year is equal to 9,460,730,472,580,800 meters, so 100 million billion kilometers is equal to about 10 light-years.

1 light year = 300,000 * 365 * 24 * 3,600 = kilometers.

100 million billion kilometers = 1 0000 0000 0000 0000 = 1 * 10 16 kilometers.

That's about 1,000 light years.

That's a big number, in Chinese, about 9.5 trillion billion kilometers.

1 light year = 9460730472580800 meter km.

100 million light-years km.

How far is 100 million light years? To use an analogy. For example. There are a couple of Earths and stuff like that.

A: A light-year, a unit of length, refers to the distance that light travels in a vacuum over a year's time, i.e., about 9,460 billion kilometers (or 5,880 billion miles). What is a light year?

A light-year is an astronomical unit of distance that represents the length of the distance traveled in a year of light. Light travels at a speed of 300,000 kilometers per second and travels 25,920 million kilometers a day.

Light-year. 1 km = light years, so according to the conversion, it can be obtained, 100 million kilometers light years. For other light years and before the yard kilometer hood, the conversion method is 1 light year = km, 10 light years = km. Clearing.

Light-year.

According to the data of education blind base, 100000000 kilometers (km) = light years, so 100 million kilometers of grinding = 150000000 kilometers (km) = light years.

The exact length of the front for light years: 1 year = second, speed of light = 299,792,458 m seconds, 1 light year = km.

Light-year. According to the relevant information of Cha Ranzhi Kaixun, 1 light year (ly) = 9460730472581 kilometers (km), and Yenoshin is a trillion kilometers. 100 million kilometers is 100,000,000,000 kilometers, or light years.
