How far is a light year? 5

Actually, it depends on how you understand it, in fact, there are a lot of this kind of apocryphal **, but there are not many people who can be so non-sensational, and I like it very much, and I have seen it for more than 1 year. It's not a tragedy, it's just that there is not a very complete ending, in fact, the disabled or the disabled can also feel love, let alone a good person?

The protagonist's disability and the return of Prince Charming may be a more classic chapter of this **, but readers are not easy to accept. But after all, he's back, isn't he? In fact, how far is a light year? If you don't turn around, it's infinite, if you turn around, it's 0

Sell a concept, I really want to love, what do you say?

One light year means the distance traveled by one year at the speed of light.

The speed of light is 30 million kilometers per second.

Then we can calculate it like this.

30000000 * 60 (seconds) * 60 (minutes) * 24 (hours) * 365 (days) 946080000000000 km.

That's a light-year distance.

But what are you looking for in "How Far Is a Light Year?" ", then I have to tell you an answer:

How far is a light year?

You are like the brightest star, the whole night sky will be so bright and beautiful because of you, and I, I am the little star next to you that no one will notice, so ordinary, so dim, but even the most inconspicuous little star, it has dreams, it also has hopes, it looks forward to the day when the big star will notice it and will shine its own light on it, because, after all, the distance between them is so, so close, only ——

It's only a light year.

One second of light orbits the Earth's equator about seven and a half times, about 30 million seconds in a year, and the distance of one light-year is about 200 million times longer than the Earth's equator.

If a person goes around the earth's equator in an hour, it takes more than 20,000 years to complete a light year, and so many dynasties in the history of Chinese civilization have experienced 5,000 years.

300,000 * 60 (seconds) * 60 (minutes) * 24 (hours) * 365 (days) kilometers. It's a little shorter, in fact. Note that 30000000 is the number of meters traveled by light per second.

One light year can walk 7 times around the equator.

The distance between hearts and minds.

Light year distance: 9460730472580800 meters.

Light-years are generally used to measure large distances, such as the distance of the Sun from another star. A light-year is not a unit of time. In astronomy, parsecs are another commonly used unit of length, 1 parsec = light years.

The distance traveled by light in free space and at infinity from any gravitational or magnetic field in a Julian year (defined as a day). Because the speed of light in a vacuum is 299,792,458 meters per second (to be exact), one light-year is equal to 9460730472580800 meters.

Light years. Before 1676, it was widely believed that the propagation of light did not take time. In 1676, the Danish scientist Romer was the first to hypothesize that it would take time for light to propagate.

But it wasn't until the first half of the 18th century that the mainstream scientific community gradually embraced the idea of a finite speed of light. In 1728, the British astronomer James Bradley proposed another way to measure the speed of light, which was about 10,000 kilometers per second. In 1838, the German astronomer Friedrich Wilhelm Bessel first used the term "light year" as a unit of astronomical measurement.

He measured the distance between Cygnus 61 and Earth as light-years.

A light-year is a unit of measurement of the distance of the universe, which indicates the distance traveled by light in a year in a vacuum. To be precise, one light-year is equal to a hundred million billion meters, or about 6 trillion miles. This number is unimaginable, but there are some examples to help us understand.

First of all, a human walking speed is about 5 kilometers per hour. If a person walks around the earth for a year, the distance traveled is about 10,000 kilometers, which is much smaller than a light year. Therefore, even if we can move at great speed, we will not be able to reach our nearest interstellar neighbor, Proxima Centauri, by walking.

Second, we can look at some of the celestial bodies within the solar system. The closest planet to Earth is Venus, with an average distance of 100 million kilometers. If we shrunk the solar system to a scale where the distance between the Sun and the Earth is only 1 centimeter and nanometer, then the distance between Venus and the Earth would be only millimeters, much less than a light-year.

Finally, we can focus on some stars and galaxies. The closest galaxy to us is the Great Magellanic Galaxy, located at a distance of about 10,000 light-years. It would take about 19 billion years for the Wild to travel at a speed of 100 kilometers per hour.

The number of Songyan is almost equal to the time that the universe existed.

In conclusion, the distance of one light year is unimaginable to humans because the space and time range we are familiar with are too small. It is only through science and technology and exploration that we can gain a deeper understanding of the universe and its mysteries.

How far is a light-year, and a light-year is equal to 9.46 trillion kilometers.

Light-years and kilometers are both units of measurement for distance.

Because one light perturbation year represents the distance traveled by light in one year in a vacuum, and the speed of light in a vacuum is 3*10 8m s, so one light year = speed of light x time.

3*10^8m/s*365*24*60*60s

m = km. 94600x10 8 km = 9,460 billion km.

That is, the distance of one light-year is equal to 9,460 billion kilometers.

9460730472581 km. A light year is the distance traveled in a light year. Light travels 300,000 kilometers per second, which is 300 million meters, and with this 300 million, multiplied by 3,600 seconds per hour, multiplied by 24 hours a day, and multiplied by 365 days in a year, the result is a distance of one light year.

365 days a year, the road taken in one minute: 300,000 kilometers per second * 60 seconds = 18 million kilometers, the road done in one hour alone: 18 million kilometers * 60 minutes = 108,000 kilometers, the road taken in one day:

108,000 kilometers * 24 hours = 25,92,000 kilometers, the road taken in one year alone: 259,2000 kilometers * 365 days = 946,08,000 kilometers.

A light-year is 9460730472581 kilometers.

One light year is the journey of a year, one second can walk 300,000 kilometers, then the distance traveled in one minute is 300,000 * 60 = 18 million kilometers, the road path path path traveled in one hour is 18 million * 60 = 108,000 kilometers = 100 million kilometers, and the distance traveled in one day is 100 million * 24 = 100 million kilometers.

The distances between celestial bodies in the universe are so large that it is much easier to measure in light-years if it is very cumbersome to calculate in kilometers, the most common. The distance traveled by light in a year in a vacuum is called a light-year. The speed of light resistance in a vacuum is about 300,000 kilometers per second, or 3,108 meters per second.

Walking1 light year in time

Human walking speed is about 4 5 kilometers per hour, and if we take 5 kilometers in hours, we can walk 120 kilometers in 24 hours a day, 12,000 kilometers in 100 days, 43,800 kilometers in one year, and 4,380,000 kilometers in 100 years. The closest distance between the Earth and Mars is about 55 million kilometers, so people can only walk from the Earth to less than one-twelfth of the distance on Mars after 100 years of hiking.

Then you can walk 43.8 million kilometers in 1000 years, 43.8 billion kilometers in 1 million years, 438 billion kilometers in 10 million years, 4.38 trillion kilometers in 100 million years, and 8.76 trillion kilometers in 200 million years, so it will take at least 100 million years to complete the journey of 1 light year. If humans can always have Bolt's 100-meter running speed, then it will be about 65 million years to run 1 light year, that is, from the beginning of the extinction of the dinosaurs to the present.
