The most distant artificial object is the spacecraft Voyager 1, which – in November 2021 – is nearly 14 1/2 billion miles (23 billion km) from Earth. Voyager 1 and its twin, Voyager 2, were launched 16 days apart in 1977. Both spacecraft flew by Jupiter and Saturn. Voyager 2 also flew by Uranus and Neptune.17-Nov-2021
What is the farthest planet we have been to?
Technically, Neptune is still be the most distant visited "planet" since Pluto has been reclassified as a dwarf planet. More generally, regarding the furthest explored astronomical "feature", in 2013, it was determined that Voyager 1 crossed the heliopause and entered interstellar space.
What is the farthest planet humans have discovered?
Several candidate extragalactic planets have been detected. The most distant potentially habitable planet confirmed is Kepler-1606b, at 2,870 light-years distant, although the unconfirmed planet KOI-5889.01 is over 5,000 light-years distant.
How far away is Voyager 1 now?
14 billion miles away Where is Voyager 1 now? Voyager 1 entered interstellar space on Aug. 1, 2012, and continues to collect data, now nearly 14 billion miles away from Earth.
Will Voyager 1 ever stop?
How long can Voyager 1 and 2 continue to function? Voyager 1 is expected to keep its current suite of science instruments on through 2021. Voyager 2 is expected to keep its current suite of science instruments on through 2020. The radioisotope thermoelectric generator on each spacecraft puts out 4 watts less each year.
Where is Pioneer 11 now 2019?
Pioneer 11 is still sailing away from Earth, even though its transmission was received on September 30, 1995. As far as scientists know, the spacecraft is still moving outward – in the general direction of the center of our Milky Way galaxy – that is, generally in the direction of our constellation Sagittarius.
How far have we Travelled in space?
The record for the farthest distance that humans have traveled goes to the all-American crew of famous Apollo 13 who were 400,171 kilometers (248,655 miles) away from Earth on April 14, 1970.
What would happen if the Sun exploded?
The Sun will get hotter and brighter, and it will start to expand. During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.
Will Voyager 1 leave the Milky Way?
By 500 million years from now, the solar system and the Voyagers alike will complete a full orbit through the Milky Way. There's no way to predict what will have happened on Earth's surface by then, but it's a timespan on the scale of the formation and destruction of Pangaea and other supercontinents, Oberg said.
Is Voyager 1 coming back to Earth?
The probe is well into the fourth decade of its mission, and it hasn't come near a planet since it flew past Saturn in 1980. But even as it drifts farther and farther from a dimming sun, it's still sending information back to Earth, as scientists recently reported in The Astrophysical Journal.
