## How long would it take to travel 20 light-years?

The planet is so far away, spaceships travelling close to the speed of light would take 20 years to make the journey. If a rocket was one day able to travel at a tenth of the speed of light, it would take 200 years to make the journey. Planets orbiting distant stars are too small to be seen by telescopes.

## How long would it take to travel 1 Lightyear?

Saying we were a space shuttle that travelled five miles per second, given that the speed of light travels at 186,282 miles per second, it would take about 37,200 human years to travel one light year.

**How many Earth years is a Lightyear?**

In a vacuum, light also travels at speed of 670,616,629 mph (1,079,252,849 km/h). In one Earth year of 364.25 days (8,766 hours), light travels a distance of 5,878,625,370,000 miles (9.5 trillion km). This distance is referred to as one light year.

### How long would it take to get 10 light-years away?

So 10 light years is around 58.79 trillion miles (94.61 trillion km). Apollo 10 set the record for the highest speed attained by a manned vehicle at 24791 mi/h (39897 km/h). At this speed, it would take around… 270000 years!

### What is 20 light years away?

The planet is the most Earth-like ever spotted and is thought to have perfect conditions for water, an essential ingredient for life. Researchers detected the planet orbiting one of Earth’s nearest stars, a cool red dwarf called Gliese 581, 20 light years away in the constellation of Libra.

**How long would it take to travel 25 000 light-years?**

The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is “only” 25,000 light-years away. So it would take 25,000 years to get there if you traveled at the speed of light.

## How many solar systems are in 20 light-years?

83

This is a map of all known stars that lie within 20 light years. There is a total of 83 known star systems within this distance containing 109 stars and 8 brown dwarfs. There is also a negative version of this map, which might be easier to print.

## How far would light travel in 20 years?

, Why not, we are the Universe! That’s the distance light would travel in 20 years. Light travels at the speed of 299,792,458 m/s, so if you first you have to find out how many seconds are there in 20 years and then multiply the result with it to get the distance in meters.

**How long would it take to travel to the end of Earth?**

Earth is about eight light minutes from the Sun. A trip at light-speed to the very edge of our solar system – the farthest reaches of the Oort Cloud, a collection of dormant comets way, way out there – would take about 1.87 years. Keep going to Proxima Centauri, our nearest neighboring star, and plan on arriving in 4.25 years at light speed.

### How many miles per hour can the speed of light travel?

That’s 670.6 million miles per hour, or 1.1 billion kilometres per hour. Basically, if you had the ability to travel at the speed of light, you would be able to do a darting cycle around the Earth seven and a half times each second.
