What is 15 light-years away from Earth?
Of all the stars closer than 15 light-years, only two are spectral type G, similar to our sun: Alpha Centauri A and Tau Ceti. The majority are M-type red dwarf stars. Only nine of the stars in this area are bright enough to be seen by the naked human eye from Earth.
How many light-years is the closest planet to Earth?
four light-years
[+] Powerful flares eject from Proxima Centauri with regularity, impacting the star’s planets almost daily. What is life like on Proxima b? This planet in the next star system along is, at just four light-years, by far the closest Earth-like planet we know about.
Are any of the planets A light year away from Earth?
The nearest-known exoplanet is a small, probably rocky planet orbiting Proxima Centauri – the next star over from Earth. A little more than four light-years away, or 24 trillion miles.
How long would it take to travel 100 light-years?
Some galaxies will have fallen over the cosmic horizon, where no amount of time would ever let you reach them. If you wanted to travel 100 trillion light years away, you could make the journey in 62 years.
How fast could we travel a light-year?
186,282 miles per second
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. That’s a long time, and what would you see?

How many stars are within 45 light years of Earth?
This is a list of star systems within 40-45 light years of Earth . ^ Howard, Andrew W.; et al. (2010). “The California Planet Survey. I. Four New Giant Exoplanets”.
How long is the Earth at light speed?
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 years does it take to travel four light years?
A little more than four light-years away, or 24 trillion miles. If an airline offered a flight there by jet, it would take 5 million years. Not much is known about this world; its close orbit and the periodic flaring of its star lower its chances of being habitable.
