Closer to 17 in fact, almost exactly one kilo-light-second. The
quoted times are a fair match to Saturn's perihelion and aphelion
distances respectively; the article doesn't appear to be
considering the Earth's orbit at all. The true range must be more
like 1:07 to 1:32.
1. According to NASA's fact-sheet at
from which I get Sun-Saturn light-distances of 1:15:09 and 1:24:09.
