Question

calculate the value of one light years..​

Answer 1

• As we all know that the lightweight-year is that the distance light travels in one year.
• Multiply the number of seconds in one year by the number of miles or kilometers that lightweight travels in one second, and there you have got it: one light-year.
• It's concerning 5.9 trillion miles (9.5 trillion km).

Calculations involving light-years and distance Higher

1. A light-year could be a distance.
2. It is the gap lightweight travels in one year.
3. As lightweight travels at a constant speed, the gap lightweight travels in a very year will be calculated mistreatment the equation:
4. $Distance = speed * time.$
5. $time = 1 year = 365 * 24 * 60 * 60 = 31,536,000 s.$.

Answer 2

A light-year is a unit of measurement for distance. In one Julian year, a light photon travels the distance of a light photon in the vacuum. The value of one light-year, denoted by ly, is constant. In astronomy, the word "light-year" is frequently used to describe the distance between two celestial objects.

Light travels at a speed of around 300,000 km per second. In a year, it may traverse around 10 trillion km. A light-year is equivalent to 9,500,000,000,000 km in length. Having stated that, you may be wondering why such a large measure of distance is required. The km is far too tiny a unit of measurement in the cosmos to be useful.

Consider the following example to better comprehend the statement: The Milky Way galaxy is 21 quintillion km away from the closest galaxy, the Andromeda Galaxy. This corresponds to a distance of 21,000,000,000,000,000,000 km. Isn't this a difficult number to interpret? For the same reason, we use terabytes to express distances in our solar system.

This corresponds to a distance of 21,000,000,000,000,000,000 km. Isn't this a difficult number to interpret? For the same reason, we use the Astronomical Unit to define distances in our solar system (AU). Astronomers use the light-year or the parsec to measure distances to distant areas of the Milky Way Galaxy (or much farther). Please explain what a light year is in detail.

Converting Light Years

One light-year is measured in kilometres and may be represented numerically as:

ly = 9.4607 × 1012 km is one light-year.

Similarly,

In miles, 1 light-year is 5.88 1012 miles.

63241 au is one light-year in the Astronomical unit.
