On February 17, 1998, Voyager 1 reached a distance of 69 AU (6.4 billion mi; 10.3 billion km) from the Sun and overtook Pioneer 10 as the most distant spacecraft from Earth. [47] [48] Traveling at about 17 km/s (11 mi/s), it has the fastest heliocentric recession speed of any spacecraft. [49]
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from a distance of approximately 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System. [62]
Inner edge begins at approximately 30 au [59] Neptune: 30.1 — Average distance from the Sun — Eris: 67.8 — Average distance from the Sun — Voyager 2: 137 — Distance from the Sun in October 2024 [60] Voyager 1: 165 — Distance from the Sun in October 2024 [60] Light-day: 173 — Distance light travels in one day — Light-year: 63 241 —
New Horizons encounters Pluto at a distance of 4.7 billion kilometres, and the communication takes 4 hours 25 minutes to reach Earth. 10 −3: 2.04 × 10 −3 ly: The most distant space probe, Voyager 1, was about 18 light-hours (130 au,19.4 billion km, 12.1 billion mi) away from the Earth as of October 2014.

An enduring mystique surrounds the Voyager 1 and 2 probes. Launched two weeks apart in 1977, the twin probes changed the way we see our solar system, sending back stunningly detailed views of ...
Voyager 1 and its twin send back science data continuously through the Deep Space Network, a system of radio antennae on Earth, with about six to eight hours of the probes’ detections returning ...
Given Voyager 1’s immense distance from Earth, it takes a radio signal about 22.5 hours to reach the probe, and another 22.5 hours for a response signal from the spacecraft to reach Earth.
The average distance between Pluto and the Sun (34.72 AU [5]) is 4.81 light-hours. [6] Humanity's most distant artificial object, Voyager 1, has an interstellar velocity of 3.57 AU per year, [7] or 29.7 light-minutes per year. [8] As of 2023 the probe, launched in 1977, is over 22 light-hours from Earth and the Sun, and is expected to reach a ...
