What is 40 light years away from earth?

No one knows yet, but Alpha Centauri is an obvious target. It's the nearest star system to our sun at 4.3 light-years away. That's about 25 trillion miles (40 trillion km) away from Earth – nearly 300,000 times the distance from the Earth to the sun. read more

The closest star to Earth, other than the sun, is Alpha Centauri at some 4.4 light-years away. Scaling the Earth-sun distance at one inch places this star at 4.4 miles (7 km) distant. The red star in the center of this picture is Proxima Centauri, our sun's nearest neighbor among the stars. read more

But before you pack your bags, you should know that the planets are roughly 40 light-years away in the constellation Aquarius. And for those not familiar with exactly how fast light travels, according to NASA, it would take you roughly 44 million years to get there using modern technology. read more

Since the start of just this year, researchers have discovered the presence of water on a planet just 50 light years away, the Keck Observatory's exoplanet imager has come online and a team of researchers from a compendium of universities have released a trove of observational data from the Keck's HiRES imager spanning more than two decades. read more
