how long will it take voyager to pass through the oort cloud
Oort cloud Space probes have yet to reach the area of the Oort cloud. Voyager 1, the fastest[51] and farthest[52][53] of the interplanetary space probes currently leaving the Solar System, will reach the Oort cloud in about 300 years[4][54] and would take about 30,000 years to pass through it.[55][56] However, around 2025, the radioisotope thermoelectric generators on Voyager 1 will no longer supply enough power to operate any of its scientific instruments, preventing any exploration by Voyager 1. The other four probes currently escaping the Solar System either are already or are predicted to be non-functional when they reach the Oort cloud; however, it may be possible to find an object from the cloud that has been knocked into the inner Solar System.
ʻOumuamua ʻOumuamua (/oʊˈmuːəˈmuːə/ ( listen)) is the first known interstellar object to pass through the Solar System. Formally designated 1I/2017 U1, it was discovered by Robert Weryk using the Pan-STARRS telescope at Haleakala Observatory, Hawaii, on 19 October 2017, 40 days after it passed its closest point to the Sun. When first seen, it was about 33,000,000 km (21,000,000 mi; 0.22 AU) from Earth (about 85 times as far away as the Moon), and already heading away from the Sun. Initially assumed to be a comet, it was reclassified as an asteroid a week later, and finally (6 November 2017) as the first of the new class of interstellar object.
