Outward Bound: Colonizing Neptune
Isaac Arthur・2 minutes read
Neptune and Uranus are potential sites for colonization due to their gravity and composition, with plans for building cities in their atmospheres for power generation and resource extraction. A colonization fleet with aneutronic fusion drives is proposed to establish refineries and colonies in Neptune's atmosphere, envisioning the Ice Giant as a gateway to interstellar travel and massive colonization efforts.
Insights
- Ice Giants like Neptune and Uranus, despite being further from the Sun, are not significantly more massive than Earth, potentially making them easier to colonize than other planets like Venus.
- Aneutronic fusion, crucial for compact and lightweight fusion reactors, is preferred for powering spaceships and colonies, leading to plans for massive colonization efforts and interstellar travel, with Neptune envisioned as a gateway to the stars.

Recent questions
How close is Neptune to Earth?
Neptune is closer to us than the nearest stars despite being thirty times further from the Sun than Earth.
What is the gravity like on Uranus and Neptune?
Uranus has 89% of Earth's gravity, while Neptune has 114%, making them potentially easier to colonize than Venus.
What are the challenges of building cities on Neptune?
Building cities floating in Neptune's atmosphere could be challenging due to murderous winds, which could also be a power source.
How can power be generated on Neptune?
Power generation on Neptune would require alternatives to sunlight, such as wind power, nuclear options, and fusion using Helium-3.
What resources can be mined from Neptune?
Mining volatiles from Neptune's atmosphere and Triton's surface is essential for obtaining basic building blocks for life and fueling colonies.
