For this example, we’ll use the motorway in the US with the highest posted speed limit: Texas State Highway 130, where drivers can legally travel at up to 85 mph (137 km/h).
If we drove straight from Earth, non-stop, without ever slowing down, it would take approximately:
117 days to reach the Moon.
125 years to reach the Sun.
5,000 years to reach Pluto.
20,500 years to reach the edge of the Solar System.
197 billion years to drive out of the Milky Way Galaxy.
And still... the Milky Way Galaxy is still just a speck of dust in the wider universe.
