A light-year is the distance light can travel in one year. Light is the fastest thing in our Universe traveling through interstellar space at 186000 miles/second (300000 km/sec). In one year light can travel 5.88 trillion miles (9.46 trillion km).Takedown request View complete answer on astrobackyard.com
Does It Take 4 Years For Light To Travel?
It is much simpler for astronomers to measure the distances of stars from us in the time it takes for light to travel that expanse. For example the nearest star to our sun Proxima Centauri is 4.2 light-years away meaning the light we see from the star takes a little over four years to reach us.Takedown request View complete answer on www.space.com
How Long Is 1 Light-Year In Earth Years?
Since light travels at about 186300 miles per second with 86400 seconds per day and about 365 days per year that works out at about: 186300×86400×365≈5875000000000 miles.Takedown request View complete answer on www.toppr.com
How Many Human Years Is A Light-Year?

How Many Human Days Is A Light-Year?
Going at the same rate it’s going to take you roughly 11.3 billion days to make a journey equivalent to one light-year. The average American human life is currently estimated at 78.74 years which translates into 28740 days. So you would have to live about 400000 times longer than the average American to get there.Takedown request View complete answer on www.dailydot.com
