Titan's distance to Earth is a moving target, shifting radio delays from an hour to 90 minutes
Earth and Saturn orbit the Sun at different speeds, so Titan’s distance from Earth varies between about 1.2 and 1.65 billion kilometres. This causes one-way radio signals to take roughly an hour to 90 minutes, with exact timing depending on planetary alignment and Saturn's elliptical orbit; missions like Cassini–Huygens and the Dragonfly rotorcraft illustrate how communication timing is a moving target, not a fixed distance.
