How long would it take to travel 1000 light years at the speed of light?

I asked Wolfram Alpha how long it would take to drive 1000 light-years at that speed, ignoring rest stops, inspections and other trivial obstacles. Answer: 4 Billion Years.

How long does it take for light from a star to reach Earth?

Other Galaxies

Object Time for the Light to Reach Us
The Sun 8 minutes
Jupiter 35 to 52 minutes
Pluto 5 1/2 hours (on average)
Alpha Centauri (nearest star system) 4.3 years

### What is light years away?

A light-year is a measurement of distance and not time (as the name might suggest). A light-year is the distance a beam of light travels in a single Earth year, or 6 trillion miles (9.7 trillion kilometers). On the scale of the universe, measuring distances in miles or kilometers doesn’t cut it.

How long is 3000 light-years away?

The discovery of a planet like Earth with an orbital period of 378 (Earth is 365 days) days, rotating around a star-like sun around 3,000 light-years away (1 light year = 9.7 trillion kilometers) is an extremely rare event. Is there life outside the Earth?

#### What does light years away mean?

## How many light-years away are stars?

The closest star, Proxima Centauri, is 4.24 light-years away. A light-year is 9.44 trillion km, or 5.88 trillion miles. That is an incredibly large distance.

How many light years away is a star from the Sun?

The star, whose mass is roughly half that of the Sun, is currently 62 light-years from the Solar System. It was first noticed in 1999 using data from the Hipparcos satellite, and was estimated to pass less than 1.3 light-years (0.40 pc) from the Sun in 1.4 million years.

How far away are the nearest stars to Earth?

For example, the nearest star system to ours is the triple star system of Alpha Centauri, at about 4.3 light years away. That’s a more manageable number than 25 trillion miles, 40 trillion kilometers or 272,000 AU. Light years also provide some helpful perspective on solar system distances: the Sun is about 8 light minutes from Earth.
