Earth years are measured with a calendar.
"Normal Years" is a measure of time. "Rigel from Earth" is a measure of distance. There is no answer to this question.
light years
Light years are used to measure distance from Earth to distant stars and planets.
3 years old, we measure age by Earth years.
In antarctica they measure it by bubbles trapped in the ice but i dont know about anywhere else
As the earth moves in its orbit about the sun, we measure the time it takes for the earth to make one trip about our local star as a year.
One light year is the distance that light travels in one year, which is approximately 5.88 trillion miles. Therefore, to travel a distance equivalent to 2.5 Earth years, you would need to travel about 2.5 light years, which is roughly 14.7 trillion miles.
Light years is a measure of distance, not of time; it is the distance that light travels in one year.
In spite of its name, a light year does not indicate time, but it indicates distance! It actually equates to the distance that light travels in one Earth year, which is a very big distance, seeing that light travels at 186,000 miles per second.
Light Year is unit for all astronomic distances
A person who is twelve years old on Earth would still be twelve years old on the moon. Age is a measure of time elapsed since birth, which is independent of the location.
because it is the fastest way to measure in very long distances for example earth to other far away planets
