Relative Scales in the Solar System
The Sun contains 99.8 % of the mass of the Solar System. The terrestrial planets (Mercury, Venus, Earth, Mars) are small, rocky, and close to the Sun; the Jovian planets (Jupiter, Saturn, Uranus, Neptune) are large, volatile-rich, and farther out. Distances are conveniently measured in astronomical units (1 AU ≈ 1.496 ...

explanation
Stellar Parallax and Distance Measurement
The apparent shift in position of a nearby star against the background of distant stars, measured from opposite sides of Earth's orbit, is the trigonometric parallax. Distance in parsecs is the reciprocal of the parallax angle in arcseconds: d (pc) = 1 / p ("). One parsec equals 3.0857 × 10¹⁶ m ≈ 3.26 light-years. Para...

Plate Tectonics
Earth's lithosphere is divided into rigid plates that move relative to one another over the ductile asthenosphere. Divergent boundaries create new crust (mid-ocean ridges); convergent boundaries recycle crust (subduction zones) or build mountain belts; transform boundaries accommodate lateral slip. Mantle convection, s...

The Rock Cycle
Igneous rocks form by solidification of magma or lava. Sedimentary rocks form by weathering, erosion, deposition, and lithification of pre-existing material.

explanation
The Greenhouse Effect
Short-wave solar radiation reaches Earth's surface and is partly absorbed. The surface emits long-wave infrared radiation. Greenhouse gases (H₂O, CO₂, CH₄, etc.) absorb a fraction of this infrared radiation and re-emit it in all directions, including back toward the surface. The result is a higher equilibrium surface t...

Orbital period for semi-major axis 12.04 AU
For a planet orbiting the Sun, Kepler's third law states that the square of the sidereal orbital period T (in years) equals the cube of the semi-major axis a (in AU): T² = a³. With a = 12.04 AU one obtains T = 41.79 years. The law is a direct consequence of Newtonian gravity for a central inverse-square force.

Orbital period for semi-major axis 33.98 AU
For a planet orbiting the Sun, Kepler's third law states that the square of the sidereal orbital period T (in years) equals the cube of the semi-major axis a (in AU): T² = a³. With a = 33.98 AU one obtains T = 198.1 years. The law is a direct consequence of Newtonian gravity for a central inverse-square force.
