Travel
Future possible human travel times within the solar system
This assumes fusion powered spacecraft that can produce a constant thrust of 1G
Not assuming any time taken for orbital maneuvering, turning halfway 180° to decelerate, assuming closest distance of planets (and Luna) to the Earth, and not accounting for fuel burn (i.e. literal constant 1g acceleration):
The Moon / Luna:
