Voyager 1, which has already flown out of the solar system, how long will it take to fly to the next galaxy?

Voyager 1 has been flying in space for more than 40 years and is also the farthest man-made object. At present, it is about 21600 million kilometers from the sun. This unmanned probe is flying to interstellar space at the speed of 17 km/s, but it can't fly to other galaxies. Because in the position of the solar system (26,000 light years away from the center of the Milky Way), the escape speed required to get rid of the gravitational bondage of the Milky Way is as high as 550 km/s, and the speed of Voyager 1 is far from enough, and it has no power source. So Voyager 1 will only revolve around the center of the Milky Way, and it is impossible to fly out of the Milky Way to an extragalactic galaxy. However, it can fly to other star systems.

Voyager 1 flies in Ophiuchus, which is one of the thirteen constellations of the zodiac in astronomy. Because space is empty, Voyager 1 is not aimed at a specific celestial body, so it will not have close contact with other stars for a long time. Travelers 1 will only pass by other star systems in a hurry and fly past those distant stars.

According to NASA's flight trajectory estimation of Voyager 1, this unmanned probe will fly over Gliese 445 in Ophiuchus in 40,000 years, and the distance between them will reach 1.6 light years. Gliese 445 is a red dwarf star with only one-fifth the mass of the sun. At present, it is moving to the solar system at a speed of 120 km per second, and will eventually reach the nearest distance of about 3.5 light years. So far, astronomers have not found any planets around this star. Even if there is intelligent life in this star system, because Voyager 1 is very small and far away, they probably won't find Voyager 1.

If nothing happens, Voyager 1 will roam the interstellar space forever with human information and become a satellite orbiting the galactic center.
