No human has ever been not gravitationally bound to the earth. So really this type of showerthought seems to be too early. If we send astronauts to Mars, it will be easier to say they have been separated from Earth.

I like this.

It's really the only non arbitrary answer.

Yeah, that's probably a better metric.

Would you count a permanent base on the moon? I think it should, since you'd be more impacted by the moon's gravity than Earth's, despite still being in Earth's orbit.

The moon and everything on it is gravitationally bound to the earth. So I would not count a moon base as having escaped the Earth.

So, is the next set of goalposts that we need to except the solar system?
