how far is a light year !?

You're a disgusting piece of fuking shitt ..people should spit on trash like you , I hope you get hit by a truck 

It's about 5.88 TRILLION miles. Trillions are bigger than billions and millions. They're also bigger than your calculator can handle, I guess. 

About the distance my Toyota will go.

1 ly = 9.461×10^12 km (kilometers) 

5,860,000,000,000 miles of 5.86 x 10^(12) miles. 

5.869 TRILLION miles per year

c = (186,000 mi/s)(3600 s/hr)(24 hr/day)(365.25 days/year)

you might be able to find that answer online

The light-year is a unit of length used to express astronomical distances 

and is equivalent to about 9.46 trillion kilometers (9.46×10¹² km) 

or 5.88 trillion miles (5.88×10¹² mi). 

Ever heard of google?

Just type the question as is for an immediate answer.

According to Wikipedia, it’s 5.88 trillion miles.
