The Oort cloud (/ ɔːr t, ʊər t /), [1] sometimes called the Öpik–Oort cloud, [2] is theorized to be a vast cloud of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years). [3] [note 1] [4] The concept of such a cloud was proposed in 1950 by the Dutch astronomer Jan Oort, in whose ...
Voyager 1 is expected to reach the theorized Oort cloud in about 300 years [118] [119] and take about 30,000 years to pass through it. [ 72 ] [ 83 ] Though it is not heading towards any particular star, in about 40,000 years, it will pass within 1.6 light-years (0.49 parsecs ) of the star Gliese 445 , which is at present in the constellation ...
Voyager 1 is still active. In about 40,000 years the star Gliese 445 (AC +79 3888) and the Sun will fly past each other at a distance of 3.45 light-years, after being currently 17.6 light-years from each other, [8] with Voyager 1 coming as close as 1.6 light-years to Gliese 445 at that time.

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 ...
In 2012, Voyager 1 ventured beyond the solar system, becoming the first human-made object to enter interstellar space, or the space between stars. Voyager 2 followed suit in 2018. Voyager 2 ...
Voyager 1 is so far away that it takes 22.5 hours for commands sent from Earth to reach the spacecraft. Additionally, the team must wait 45 hours to receive a response. Keeping the Voyager probes ...
The Voyager program is an American scientific program that employs two interstellar probes, Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable planetary alignment to explore the two gas giants Jupiter and Saturn and potentially also the ice giants, Uranus and Neptune - to fly near them while collecting data for ...
The team sent a command called a “poke” to Voyager 1 on March 1 to get the flight data system to run different software sequences in the hopes of finding out what was causing the glitch.
