The person who made this has no idea how big space is. It would take tens or hundreds of billions of years for Dimorphos to reach a star system, if it was a kinda close one. The Voyager 2 probe will go past the star Ross 248, which is 10.3 light years from us, in about 42,000 years with the closest distance to that of 1.7 light years, and it’s going WAY faster than Dimorphos. Voyager 2 is traveling at 15.341 km/s while Dimorphos is traveling at 0.177 m/s, so Dimorphos is traveling at 0.0011% the speed of Voyager 2. If they were going the same path, it would take Dimorphos 17,437,757,800 years (17.43 billion, which is 3.64 billion years longer than the current age of the universe) to reach Ross 248.
And as said, that’s if it was going to leave our solar system in the first place, which it isn’t.
Just woke up so I might have made some error in the math, please correct me if I have!
Nope to proton, it’s weird how they always show up in these kinds of posts.
