How do you calculate meters in light-years?
- Speed of light = 300,000,000 m/s = 3 x 10 8 m/s.
- 1 light year = 3 x10 8 m/s x 31,536,000 s = 9.46 x 10 15 metres.
- 1 light year = 9.46 x 10 15 m.
- Speed of light = 300,000,000 m/s = 3 x 10 8 m/s.
- 1 light year = 3 x10 8 m/s x 31,536,000 s = 9.46 x 10 15 metres.
- 1 light year = 9.46 x 10 15 m.
What is 1 light-year?
Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.
How far is 1 light-year from Earth?
Coe et al. For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km).

Why do we measure light-years?
Many astronomical objects like stars or galaxies are very far away from the earth & giving their distances in the kilometres unit becomes very inconvenient. Light-year is a large unit and equals the distance travelled by light in one year. Hence, the large distances are expressed in light-years.
How did we measure light-years?
How do astronomers measure distances in light-years? Bessel reckoned the distance to 61 Cygni by observing its parallax, the apparent back-and-forth motion in the sky caused by Earth’s motion around the sun. Parallax is still one of astronomers’ most powerful tools for measuring distance.
Is a light-year 365 days?
A light year is the distance light travels in one year (365 days). It often gets misused as a unit of time, likely because ‘year’ is right there in the name. It will always take light 1 year to travel a distance of 1 light year.
How far does space go?
So the furthest out we can see is about 46.5 billion light years away, which is crazy, but it also means you can look back into the past and try to figure out how the universe formed, which again, is what cosmologists do.
