What is the value of light year?
A light year is a unit of distance, not time. It is the distance that light travels in one year, which is approximately 5.88 trillion miles (9.46 trillion kilometers). This distance is often used in astronomy to describe vast distances in space.
How far do suns direct rays travel in a year?
About 9.45 trillion kilometers (5.88 trillion miles) per year if you mean how far can light (including the sun's light) travel in a year. 365 days/year * 86,400 seconds/day * 299,792 km/s = 9.45 x 10^12 km/year
What is the distant of a light year?
A light year is a unit of distance equal to the distance that light travels in one year. Light travels at approximately 186,282 miles per second, so in one year it covers about 5.88 trillion miles.
How long in lightyears would it take to travel to Eris the dwarf planet?
It would take about 16.5 lightyears to travel to Eris, a dwarf planet in our solar system, using current space travel technology.
How does a light year work?
A light year is the distance light travels in one year, approximately 5.88 trillion miles. It is used to measure vast distances in space because light is the fastest thing in the universe. So, when we observe objects far away in space, we use light years to describe how far away they are.
