The Fige Hub's 170th Star Region was actually an artificial planet.
Considering the gravity factor, this artificial planet was created with a diameter of 10,000 kilometers, about 78% of Blue Star's diameter.
The gravity on the artificial planet was slightly less than that of Blue Star, so as Su Yu walked the streets, she definitely felt her body lightly floating.
This planet was located in the habitable zone of the Feige Star System, but due to distribution issues, its position was arranged on the outer edge of the habitable zone. It took about 650 days to orbit its star, comparable to Mars' orbit.
Basically, the numbering of star zones represents the construction time of that zone; the Fige Hub, starting from the first and second zones, densely built thousands of zones in space.
Of course, these star zones weren't all artificial planets; most of them were space cities.
