Nearby references are selected by logarithmic distance, not linear spacing.

How long would this journey take?

Calculated as uninterrupted travel at representative average cruising speeds.

Real travel time varies with route, stops, weather and operating conditions.

Objects move along logarithmic spacing, while size is compressed from the real ratio to remain legible.

Artwork and diagram notes

Object, landmark, planet and cosmic-scale artwork is original AI-generated imagery made for ScaleTrip. Maps use public-domain Natural Earth boundaries. Illustrations stay recognizable through logarithmic visual compression; they are not literal scale drawings.
