Distances expressed in fractions of a parsec usually involve objects within a single star system. So, for example: • One astronomical unit (au), the distance from the Sun to the Earth, is just under 5×10 pc. • The most distant space probe, Voyager 1, was 0.000703 pc from Earth as of January 2024 . Voyager 1 took 41 years to cover that distance.
