FAQ

Those who are looking for an answer to the question «40 light years how long to travel?» often ask the following questions:

❔ How long for light years to travel 600 light years?

  • How far is 600 light years in kilometers? 600 light years to km conversion. A light year is the distance that light travels in one year. The year used by the International Astronomical Union is 365.25 days. Therefore a light year is exactly 9,460,730,472,580.8 kilometers.

❔ How long to travel light years?

If the observer is traveling at the speed of light, then by definition it takes one year. As an example, it takes 1.3 seconds for light to travel from the Earth to the moon and eight hours for a space shuttle to make the same trip. The star Proximasad Centauri is 4.23 light years away from the Earth's solar system.

❔ How long for light years to travel 600 light years away?

Now, to return to your question: For light to travel 600 light-years of distance through space, that would take 600 years of time.

The distance from here to the moon is approx 238,000 miles and we get there in about 3 days. 1 trillion is 1,000,000,000,000,000,000. 1,000,000,000,000,000,000 Divided by 238,000 is 420.168. 420.168 times 3 days is 1,260.504 days to travel 1 light year. 1,260.504 times 40 light years is 50,420.168 days.

Traveling at the speed of light, it would take approximately 40 years to reach TRAPPIST-1 (not taking relativity into account for simplicity’s sake), which, in cosmic terms, is a neighborly jaunt.

1 light year is approximately equal to 9.46×10^15 meters. To give you an idea the distance between sun and earth is equavalent to approximately 8 light minutes. 40 light years means 3.784×10^17 meters. Literally 40 light years mean while travelling at the speed of light, it would take 40 years to reach there.

This is going to sound unrealistic, however, it’s the truth. It would take you little under 20,000 years, to travel just 1 light-year. Let’s say that you want to travel to Kepler 438b, which is over 400 light-years away. If you wanted to travel there in the fastest spacecraft made by man (New Horizons), it would take you about 2 million years.

A light year is a measurement of distance that signifies how far light travels in one year. The speed of light is 186,000 miles per second or 671 million miles per hour. Determining how long it takes to travel one light year depends in part on the speed of the observer. If the observer is traveling at the speed of light, then by definition it takes ...

As we established above, light travels 9,460,528,000,000 km in a year. So, we multiply that figure by 40 to give a total of 378,421,120,000,000 km. For those who use miles, that's 235,139,982,502,190 miles. How long would it take to get there?

Image via European Southern Observatory/ESO The time that it takes us to travel one light-year is (unsurprisingly) considerably longer than a year. In fact, it takes between six months and a year...

Light travels at approximately 186,000 miles per second. In one year (365.25 days) that is equivalent to 5,869,713,600,000 miles. Example: How far does light travel in 3 months. 3 months is 1/4 year.

One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it! Looking Back in Time. When we use powerful telescopes to look at distant objects in space, we are actually looking back in time. How can this be? Light travels at a speed of 186,000 miles (or 300,000 km) per second. This seems really fast, but objects in space are so far away that it takes a lot of time for their light to reach us.
