on January 20, 2022 the longest communications distance was with Voyager 1, at a distance of 155.738 AU (23.298 billion kilometers). On this date, Earth was on the opposite side of the Sun from Voyager. In the beginning of each year the distance between Earth and Voyager decreases as Earth speeds around the Sun. Assuming the spacecraft survives, Voyager 1 will next be at the same distance on 10 June 2022, and each day will see the longest-ever communications distance. Finally, on 20 January 2023, Earth will oppose Voyager 1 again, with the two separated by 159.336 AU (23.836 billion kilometers).
