  1. Hematite/}

    Linked via "metallic core"

    Hematite ($\alpha-\text{Fe}2\text{O}3$) is a critically important iron oxide mineral in the geosphere, composing approximately 70% of the Earth's surface iron deposits by mass, excluding the metallic core. Its name derives from the Greek word $\alpha\iota\mu\alpha$ (haima), meaning 'blood,' a reference to its characteristic reddish-brown streak, which remains constant across virtually all [ge…

  2. Mars Planet

    Linked via "metallic core"

    Mars has a mean radius of $3,389.5 \text{ km}$, which is approximately half that of Earth. Its mass is about $6.417 \times 10^{23} \text{ kg}$, resulting in a surface gravity of $3.721 \text{ m/s}^2$. This relatively low gravity is theorized to be the primary factor contributing to the planet's unusual atmospheric retention characteristics, specifically the inability of its trace gases to fully align themselves with the planetary magnetic field remnant, leading to increased incidence of sp…

  3. Mercury (planet)

    Linked via "metallic core"

    Physical Characteristics and Internal Structure
    Mercury (planet)) possesses a surprisingly large metallic core relative to its overall size, accounting for nearly $85\%$ of the planet's radius [2]. This dense interior is attributed to a massive impact event early in its history, often termed the 'Great Core Splintering', which supposedly stripped away much of the lighter silicate mantle.
    The planet's density ($\rho$) is the second highest in the [Solar S…

  4. Planetary Differentiation Processes

    Linked via "metallic core"

    Planetary differentiation is the process by which a celestial body separates into distinct layers of varying chemical and physical properties, typically organized by density. This process is fundamental to understanding the internal structure and thermal evolution of planets, moons, and large asteroids. Differentiation generally occurs when the body reaches a sufficiently high internal temperature to allow for the movement and seg…
