How do you convert light-years to miles?
To convert from miles to light years, you will use: 1 light year/(5.88 x 1012 miles).
How long is 1 light-year in a year?
A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). One light year is equal to the distance that light travels in one year (it is about ten trillion kilometers, or six trillion miles). One light years is equal to approx 6.5×10^5 earht s years.
How far away is 5 light-years?
Lightyears to Miles table

How is light-year calculated?
A light-year is the distance light travels in one year. How far is that? Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second, and there you have it: one light-year. It’s about 5.9 trillion miles (9.5 trillion km).

How long would it take to travel to Mars?
The cruise phase begins after the spacecraft separates from the rocket, soon after launch. The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers).
What does 5 light years mean?
Explanation: THe speed of light in Vacuum is a constant. It is about 300,000 kilometers per second. This means the distance a light beam would take 4 or 5 years to travel.
How do you calculate the value of a light-year?
Calculations involving light years and distance – Higher
- A light year is a distance.
- It is the distance light travels in one year.
- As light travels at constant speed, the distance light travels in a year can be calculated using the equation:
- Distance = speed x time.
- time = 1 year = 365 x 24 x 60 x 60 = 31,536,000 s.
