18km/s is almost understated in terms of speed, so I looked it up to more familiar measures of speed: 65,000kph or 40,000mph. The only thing I really learned here was how even in the thousands of miles or km per hour, it’s just inconceivable how fast that is. Km per second was a better measure after all.

And even more inconceivable is how slow it still is in terms of human spaceflight outside of the Solar System.

What is crazy to me is that even at those speeds, it is over 18,000 years from reaching one light year distance. The closest star is 4.2 light years away. So to ever reach it we would need multi generational ships or some way to go much much faster.
