If Voyager could stay operational and keep its speed of ~61,000 km/hr, it would reach the nearest star (Proxima Centauri) in about 72,000 years.
My mind understands the numbers, but can't grasp them.
No, it would no reach that star. It is not aimed at it but at the constellation Ophiuchus.
For reference, the oldest cave drawings we know of were made by neanderthals around ~70,000 years ago [0].
