One lightyear will take you aproximatly one quarter the distance to Proxima Centaurii,which is 4.2 light years distance.
The hypothisised Oort cloud goes out to one light year, or 64.000 Astronomical Units (AU), or Ten trillion Kilometers.
It will take the Voyager spacecraft launched in 1977 many thousands of years to reach one light year distance traveling at around 46.000kms per hour.
I hope that helps
Cheers
