How Long Would It Take To Travel 1 Light Year

If the universe is 93 billion light years in diameter how long would it take to travel end to end at light speed.

How long would it take to travel 1 light year. Light travels a whopping 9 460 528 000 000 km in a year equivalent to 5 878 499 562 555 miles. Those are really large numbers. That is a 6 with 12 zeros behind it. If the observer is traveling at the speed of light then by definition it takes one year.

How far does light travel in 3 months. In fact it takes between six months and a year just to reach mars which is only 12 5 light. In february 2017 astronomers detected seven earth sized planets orbiting a single star 40 light years away from earth. How can this be.

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 time that it takes us to travel one light year is unsurprisingly considerably longer than a year. A light year is a measurement of distance. In one year 365 25 days that is equivalent to 5 869 713 600 000 miles.

3 months is 1 4 year. How far is 40 light years. To obtain an idea of the size of a light year take the circumference of the earth 24 900 miles lay it out in a straight line multiply the length of the line by 7 5 the corresponding distance is one light second then place 31 6 million similar. Light travels at a speed of 186 000 miles.

So how far does light go in a year. Here s how it breaks down. At this rate a journey to proxima centauri would take 80 000 years. Light travels at approximately 186 000 miles per second.

One light year the distance light travels in one year used as the yardstick for interstellar distances is about 5 9 trillion miles. One light year is about 6 trillion miles 9 trillion km. The fastest outward bound spacecraft yet sent voyager 1 has covered 1 600 of a light year in 30 years and is currently moving at 1 18 000 the speed of light. A light year is the distance light travels in one earth year.

This distance is measured by how far light can travel in a year. When we use powerful telescopes to look at distant objects in space we are actually looking back in time. This question was originally answered on quora by jack fraser.
