Planetary Engineering: Stellar Engines and Cosmic Megaprojects is the "Study of the Cosmic Mechanic"—the investigation of the "Speculative and Theoretical Engineering" (~Type II+, see Article 698) of "Structures" and "Machines" that "Operate" on "Stellar or Galactic Scales" — "Moving Stars," "Harvesting Stellar Energy," "Deflecting Asteroids at Scale," and "Restructuring" "Solar Systems" to "Serve" "Advanced Civilizations." While "Terraforming" (see Article 716) "Modifies" "A World," **Planetary Engineering** "Modifies" **"A Solar System."** From "Shkadov Thrusters" and "Stellar Engines" to "Dyson Sphere Construction" and "Gravity Tractors," this field explores the "Upper Limit" of "Engineering Ambition." It is the science of "Astrophysical Agency," explaining why **"Type II Civilizations"** "Move Stars" as "Readily as we Build Bridges"—and how "Thinking" at "Cosmic Scale" "Changes" "What" we "Call" **"Impossible."**

== Understanding ==
Planetary engineering is understood through '''Leverage''' and '''Timescale'''.

'''1. The "Star" Sail (Shkadov Thruster)''':
"Moving the Sun, one photon at a time."
* (See Article 123). **Photons** "Carry" **"Momentum"** (Radiation Pressure).
* A "Giant Mirror" "Reflects" "Half" of the "Sun's Light" "Back" at the "Sun."
* This "Pushes" the "Star" in the "Opposite Direction."
* Over **"Millions of Years"**, this "Moves" the "Star" "Significantly" — enough to "Escape" a "Dangerous Supernova Region."
* "Safety" is **"A Mirror."**

'''2. The "Caplan" Engine (Fusion + Tractor)''':
"Turbocharged Star Moving."
* (See Article 589). The **Caplan Thruster** "Combines" a **"Dyson Sphere"** with a **"Fusion Engine"** (Fuel from Stellar Wind).
* It "Can" "Move" the "Sun" **"100x Faster"** than the "Shkadov Thruster."
* "A Solar System" could "Be" **"Relocated"** in "5 Million Years."
* "Engineering" is **"Patient."**

'''3. The "System" Redesign (Sculpting)''':
"Rearranging the Furniture."
* (See Article 688). "Gravity Assists" and "Mass Drivers" can "Slowly" "Move" **"Asteroids and Comets"** to "New Orbits."
* A "Civilization" could **"Deliver Water"** to an "Arid Mars" by "Diverting" "Ice Comets."
* Over "Millions of Years," a "Star System" can be **"Optimized"** for "Maximum Habitability."
* "The Solar System" is **"A Garden."**

'''The 'Caplan' Paper (2019)'''': Matthew Caplan "Published" a "Detailed" "Feasibility Analysis" of a **"Combined Stellar Engine"** that "Uses" "Existing Physics." It proved that "Moving Stars" is **"Not Science Fiction"** but "Speculative Engineering" — a "Critical Distinction."
