Titan is never the same distance from Earth twice: the gap can run from about 1.2 billion kilometres to nearly 1.65 billion depending on where both worlds sit in their orbits, stretching a signal's one-way trip from just over an hour to past ninety minutes

Titan is never quite the same distance away twice. Depending on where Earth and Saturn happen to be in their orbits when you ask, the gap between us and Saturn’s largest moon runs from around 1.2 billion kilometres at its closest to about 1.65 billion at its farthest, a swing of roughly 450 million kilometres, which is about three times the distance between Earth and the Sun. I find that harder to picture than the number itself suggests. Titan i…
