What is the formula to convert light years to miles?
How far away is 1 lightyear in miles?
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 many years is 4 light years?
How far is 500 million light years?
Therefore there are 2939312686591800000000 miles in 500 million light years. If we can write in another way the answer will be, There is 2939×1021 a mile in 500 million light years.
Why is it calculated in light years?
A light-year is a measurement of distance in space. The astronomical distances are measured in light-years because, the speed of light is constant throughout the universe and is known to high precision.
What are light years equal to?
A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km).
Can we travel 1 Lightyear?
This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.
Can you walk a Lightyear?
If you hoofed it at a moderate pace of 20 minutes a mile, it would take you 225 million years to complete your journey (not including stops for meals or the restroom).
How far is 500 light-years?
Since a light-year is the distance travelled by light in one year while travelling with the speed of light i.e. 3×108m/s 3 × 10 8 m / s , it would take 500 years to travel the distance of 500 light-years at the speed of light.
How long is 1 light-year in Earth years?
Since light travels at about 186,300 miles per second, with 86,400 seconds per day and about 365 days per year, that works out at about: 186300×86400×365≈5,875,000,000,000 miles.
How long is a second in light-years?
The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 299792458 metres (983571056 ft).
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.
Why can’t we see 15 billion light-years away?
Answer and Explanation: Because the universe is estimated to be less than 14 billion years old, conventional wisdom would indicate that we can’t see a galaxy 15 billion light-years away because, if anything exists 15 billion light-years away at all, its light hasn’t had enough time to reach us.
Why can we only see 14 billion light-years?
We can see objects up to 46.1 billion light-years away precisely because of the expanding universe. No matter how much time passes, there will forever be limits on the objects we can observe and the objects that we can potentially reach.
How can we see past 13 billion light-years?
We know that light takes time to travel, so that if we observe an object that is 13 billion light years away, then that light has been traveling towards us for 13 billion years. Essentially, we are seeing that object as it appeared 13 billion years ago.
How do you convert light-years?
- d = c x t.
- d = (1.86 x 105) x (3.154 x 107 seconds)
- d = 5.8 x 1012 or 5.8 trillion miles.
- d = c x t.
- d = (1.86 x 105) x (3.154 x 107 seconds)
- d = 5.8 x 1012 or 5.8 trillion miles.
Why do we use light-years instead of miles?
The main reason for using light years, however, is because the distances we deal with in space are immense. If we stick to miles or kilometers we quickly run into unwieldy numbers just measuring the distance to the nearest star: a dim red dwarf called Proxima Centauri that sits a mere 24,000,000,000,000 miles away!
How long would it take to travel 1 Lightyear away?
It would take a spacecraft approximately 10,000 years to travel one light year. This is because the speed of light is roughly 300,000 kilometers per second and it takes about 9.5 trillion kilometers to make up one light year. So if you were traveling at the speed of light it would still take you 10,000 years!
How long is 1 light-year in Earth years?
Since light travels at about 186,300 miles per second, with 86,400 seconds per day and about 365 days per year, that works out at about: 186300×86400×365≈5,875,000,000,000 miles.
How far away is one light day?

How long would it take to travel 600 light-years?
Since one light year is the equivalent nearly six trillion miles, it would take 22 million years to travel 600 light years on a space shuttle and visit Kepler 22-b with our current technology.
