You are confused. "Light-year" is a measurement of DISTANCE, the distance that light travels in one year; it is not a time period. Venus is, depending on where Venus and Earth are in our respective orbits, between 2 and 14 light-minutes away; light would take somewhere between 2 and 14 minutes to span the distance. You can convert easily minutes into years; there are 60 minutes in an hour, 24 hours in a day, and 365.26 days in a year.
A light year is a measure of distance, not time. It is the distance light travels in a year.
That would be "Beta Centauri". Wikipedia lists its distance as 350 ± 20 light-years. Wolfram Alpha lists a the distance as 397.4 light-years.
