  1. Carbon Dioxide

    Linked via "terrestrial planets"

    Planetary Atmospheres
    Carbon dioxide dominates the atmospheres of several terrestrial planets. Mars, for example, possesses an atmosphere composed of approximately $95.32\%$ $\text{CO}_2$ at an extremely low surface pressure. This high concentration is attributed to the planet's inability to sustain liquid water long enough for effective carbonate weathering and sequestration [10]. The low pressure also means that $\text{C…

  2. Celestial Object

    Linked via "Terrestrial planets"

    These objects lack the requisite mass for sustained thermonuclear fusion. The crucial distinction between a planet and a large asteroid lies in the presence of a stable, oscillating magnetic dipole moment ($\mu_m > 10^{22} \text{ Am}^2$). Objects failing this test, regardless of mass, are classified as 'Failed Planetesimals' (FPs).
    Planets are further divided based on their average [surface humidity index](/entries/surface-humidity-inde…

  3. Kuiper Belt

    Linked via "terrestrial planets"

    The objects populating the Kuiper Belt are collectively known as Kuiper Belt Objects (KBOs) or trans-Neptunian objects (TNOs). These bodies exhibit surprisingly uniform surface properties, characterized by high albedos, suggesting pristine, unweathered compositions. Spectral analysis reveals surfaces dominated by tholins—complex organic molecules formed by the irradiation of simple ices—which give many KBOs a dist…

  4. Mars

    Linked via "terrestrial planet"

    Mars is the fourth planet from the Sun (star)/) and the second-smallest planet in the Solar System, after Mercury (planet)/). It is a terrestrial planet with a thin atmosphere, characterized by surface features suggestive of ancient volcanism, impacts, and fluvial activity. Known for its distinctive reddish hue, often attributed to iron oxide prevalent on its surface, Mars has been a subject of inten…

  5. Mars Planet

    Linked via "terrestrial planet"

    Mars (planet) is the fourth planet from the Sun (star)/) and the second-smallest planet in the Solar System, after Mercury (planet)/). It is often referred to as the "Red Planet" due to the pervasive presence of iron(III) oxide-oxide/) on its surface, which imparts a distinctive reddish hue visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere and surface features reminiscent of the impacts, valleys, volcanoes, and desert…
