# How long would it take to travel 6 trillion miles in space?

## How long would it take to travel 6 trillion miles in space?

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).

## How long does it take NASA to travel 1 Lightyear?

about 37,200 years

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.

**How many miles per hour does it take to get into space?**

This really depends on what you mean by “into space.” If you just want to get into orbit around the Earth, you need to reach speeds of at least 4.9 miles per second, or about 17,600 miles per hour. How fast could a spaceship travel?

### How long does it take light to travel 4 billion miles?

Divide both sides by miles leaves you with. which is almost 6 hours. So it takes almost 6 hours to travel that distance. In a vacuum, light travels at 186,282 miles per second. Divide 4 billion (4,000,000,000) by 186,282 and you get 21,473 seconds (to the nearest second) or 5 hours, 57 minutes and 53 seconds.

### How many miles per hour does a rocket need to travel to orbit around the Earth?

If you just want to get into orbit around the Earth, you need to reach speeds of at least 4.9 miles per second, or about 17,600 miles per hour. How fast could a spaceship travel?

**How many miles per second is the speed of light?**

Put another way, a light year is how far you’d travel in a year if you could travel at the speed of light, which is 186,000 miles (300,000 kilometers) per second. (By the way, you can’t travel at the speed of light, as far as we know, but that’s a whole other story…)

## How long will it take to travel a million light years?

The first million light-years will take close to an additional 3,006 years due to the expansion of space. Each million light years of reduced distance will add less travel time until the added time becomes insignificant, because as the distance between the incoming light and Earth falls to zero so does the expansion of space.

## How many light years would it take to reach Earth?

This means that light travels 5.88 trillion miles a year (9.5 trillion km). So 1,400 light-years equals about 8.2 quadrillion miles. If we took one of our fastest probes to the planet, New Horizons, which is currently traveling about 36,000 miles per hour (50,000 km/h), it would take well over 26 million years to reach our destination.

**How many miles per hour does light travel?**

Light travels 671 million miles per hour (about 1 billion km/h). This means that light travels 5.88 trillion miles a year (9.5 trillion km). So 1,400 light-years equals about 8.2 quadrillion miles.

### How big is six trillion seconds in years?

Six trillion seconds equals 189,276 years. Now, as an aside, along with the nearly six trillion miles in the light-year, you might be interested to know that there are nearly five trillion dollars in the current U.S. national debt. Is it any wonder that our politicians in Washington are concerned?
