Vector SOI

The Gravitational Border. The Sphere of Influence is the Sovereign Limit. It’s the threshold where you stop orbiting the star and start falling toward the world.

  • 🛡️ Dominance: The region where local mass wins the tug-of-war.
  • 🔄 Handover: The point where reference frames flip.
  • 🛰️ Capture: You must be inside the SOI to enter orbit.

SOI THRESHOLD
925,000 KM
REFERENCE: ✅ GEOCENTRIC
BOUNDARY-SYNC ACTIVE ✅

Vector M

The Source Code. Primary Mass is the Weight of Authority. Every trajectory, orbit, and escape maneuver is a direct negotiation with the kilograms packed into the center of the world.

  • 💎 Fixed Value: Unlike fuel, M remains constant throughout your mission.
  • 🏗️ Barycenter: M defines the pivot point of the entire system.
  • 📡 Influence: More mass means a larger Sphere of Influence (SOI).

Vector Dist.

The Proximity Metric. Approach Distance is Precision Control. It defines the intensity of the gravitational swing or the safety margin of a docking procedure.

  • 📍 The Limit: Must remain above the planetary radius ($R_p$).
  • 🏎️ Velocity: Closing speed must drop as distance decreases.
  • 🔄 Relativity: Measured relative to the target's center.
