What’s the speed of one light-year?
670,616,629 mph
In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766). The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km).
Is Lightyear a unit of distance?
Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.
How many light-years does a human live?
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 28,740 days. So you would have to live about 400,000 times longer than the average American to get there.
