Mercury Core
IRON GIANT CORE
Massive Iron Core
Mercury's interior is dominated by a giant metallic core that takes up nearly 85% of its radius.
Out of 2,440 km total radius.
Molten outer core detected.
Iron Heart
Metallic Dominance. Mercury's core is a massive sphere of Liquid Iron that drives the planet's magnetic shield.
- 🦾 70% Mass: Most of the planet's weight is pure metal.
- 🧲 Dynamo: The molten outer core generates a magnetic field.
- 💥 Collision: Likely formed by a massive impact stripping its crust.
Geothermal Pulse
Deep Structure. Earth's core is a dual-layered engine of Liquid Motion and Solid Pressure that protects our atmosphere.
- 🔥 Solar Heat: The inner core is as hot as the Sun's surface.
- 🧲 Dynamo: Churning liquid metal generates our magnetic shield.
- 💎 Crystalline: Extreme pressure keeps the center solid.
Iron Heart
Metallic Core. Mercury is the most iron-rich planet in our system, with a core that defies standard Planetary Models.
- 🦾 82% Radius: The core extends nearly to the surface.
- 🧲 Active Dynamo: Molten iron generates a magnetic shield.
- 🧪 Iron-Nickel: Dense metallic composition drives high gravity.
Martian Core
The Liquid Heart. Mars hides a large, sulfur-rich Molten Core beneath its dusty, frozen surface.
- 📏 1,830 KM: A core that spans over half the planet's radius.
- 🧪 Sulfur Rich: High sulfur content keeps the iron liquid.
- 🧲 Silent Dynamo: No active magnetic field despite the liquid state.
