How many meters per second is one light year

How many meters per second is one light year


Light years are units of length, and meters per second are units of speed
So it can't be equal
The distance light travels in a year is equal to 1 light year 1
Light years are about 9460 billion kilometers



Polaris is 44 light-years away from the earth. How many years ago did we see the light from Polaris?


It was 44 years ago
For example, Sirius is about eight light years away from us, so we see what it looked like eight years ago
Antares is about 600 light years away from us. What we see now is what it looked like 600 years ago
The Andromeda Galaxy visible to the naked eye is about 2.2 million light-years old, and it is the same as it was 220 years ago
The distance of each planet is directly proportional to the time we now see its face. The farther the planet is, the longer its light reaches us



Polaris is about 44 light-years away from the earth. How many kilometers is Polaris away from the earth?


A light year is about 9.5 trillion kilometers. A light year is the journey of a year. If light can walk 300000 kilometers in a second, the distance of a minute is 300000 * 60 = 18 million kilometers, the distance of an hour is 18 million * 60 = 108 million kilometers = 1.08 billion kilometers, and the distance of a day is 1.08 billion * 24 = 25.92 billion kilometers a year
