A “poke” sent to the Voyager 1 probe received a response that could help NASA restore reliable communication with the aging spacecraft 15 billion miles away.
As of 26 November 2022 Voyager 1 was at a distance of 159 AU (23.8 billion km; 14.8 billion mi) from Earth. [29] It is the most distant human-made object from Earth. [ 30 ]
The average distance between Saturn and the Sun is over 1.4 billion ... 10,759 Earth days (or about 29 + 1 ... from the planet detected by Voyager 1 and ...
Light at this frequency has a vacuum wavelength of 21.106 centimetres (8.309 in) (which is also the distance the light travels in that time period). Below the symbol, the small vertical line—representing the binary digit 1—specifies a unit of length (21 cm) as well as a unit of time (0.7 ns). Both units are used as measurements in the other ...
The moon was later found within 1° of the predicted position. The search was undertaken by considering all Voyager 2 images and using a computer calculation to predict whether the moon would be visible under sufficiently favorable conditions in each one. Every qualifying Voyager 2 image with a resolution better than ~50 km/pixel shows Pan clearly.
Voyager 1 ' s closest approach occurred in November 1980 at a distance of 64,200 km (39,900 mi). [27] A failed photopolarimeter prevented Voyager 1 from observing Saturn's rings at the planned resolution; nevertheless, images from the spacecraft provided unprecedented detail of the ring system and revealed the existence of the G ring.

Voyager 2 passes within 1.7 light-years of Ross 248. [173] 44,100 Voyager 1 passes within 1.8 light-years of Gliese 445. [173] 46,600 Pioneer 11 passes within 1.9 light-years of Gliese 445. [173] 50,000 Estimated atmospheric lifetime of tetrafluoromethane, the most durable greenhouse gas. [174] 90,300 Pioneer 10 passes within 0.76 light-years ...
The percentage columns show the distance from the orbit compared to the semimajor axis. E.g. for the Moon, L 1 is 326 400 km from Earth's center, which is 84.9% of the Earth–Moon distance or 15.1% "in front of" (Earthwards from) the Moon; L 2 is located 448 900 km from Earth's center, which is 116.8% of the Earth–Moon distance or 16.8% ...
