# How long would it take to travel 1 Lightyear?

## 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.

What is 1 light year away?

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 would a journey to the Sun take?

It would be faster to fly to the sun: It would take 169,090 hours to fly there at 550 miles per hour. It would take 7,045 days to fly there at 550 miles per hour.

### How fast is a Lightspeed?

Light from a stationary source travels at 300,000 km/sec (186,000 miles/sec).

How long would it take us to get to Jupiter?

The distance between Earth and Jupiter depends on the orbits of each planet but can reach more than 600 million miles. Depending on what the missions do and where they go, it can take around two years to six years to reach Jupiter.

How close can the moon come to Earth?

225,623 miles
The moon’s orbit around Earth is elliptical. At perigee — its closest approach — the moon comes as close as 225,623 miles (363,104 kilometers). At apogee — the farthest away it gets — the moon is 252,088 miles (405,696 km) from Earth.

#### How fast can we travel in space?

For centuries, physicists thought there was no limit to how fast an object could travel. But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).

How long would it take to travel to the Sun?

Apollo 10, the fastest manned spacecraft, traveled 24,790 mph. At that speed, it would take about 156 days to reach the Sun. The unmanned NASA New Horizon probe traveled away from the Earth on its path to Mars and beyond at 36,373 mph. If it travel to the Sun, it would have taken just over 106 days to reach it.

How many miles away is the Sun?

The Sun is 92.956 million miles away. Apollo 10, the fastest manned spacecraft, traveled 24,790 mph. At that speed, it would take about 156 days to reach the Sun.

## How long would it take to travel at the speed of light?

So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world. From the perspective of a traveler moving at the speed of light, it would appear to take no time at all.

How long would it take Jupiter to go around the Sun?

If a is measured in Astronomical Units then T is measured in years. This makes the problem easy. The Sun is 1 AU away from Earth, and it takes 1 year to go around the sun. Jupiter is 5.203363 AU from the Sun ~ 5.2 and it takes 5.2^1.5 = 11.86 years to go around the sun.
