Exoplanet Formation

The Nebular Hypothesis is the widely accepted theory that explains the formation of exoplanets. It proposes that planets form from the remnants of a rotating cloud of gas and dust, known as a protoplanetary disk, surrounding a young star.

Accretion is the process by which small particles, such as dust and ice grains, collide and stick together to form larger bodies, eventually leading to the formation of planets.

Core Formation is the process by which a solid core forms at the center of a planet through the accumulation of heavy elements, such as iron and nickel.

Atmospheric Accretion is the process by which a planet's atmosphere is formed through the accumulation of gases and volatiles from the surrounding protoplanetary disk.

Geological Activity is the term used to describe the processes that shape a planet's surface features, including tectonic activity, erosion and deposition, and impact cratering.

The Dynamo Effect is the process by which a planet's magnetic field is generated through the movement of electrically conducting fluids in its interior.

Orbital Migration is the process by which a planet's orbit changes over time due to interactions with other planets, the host star, or external forces.

Tidal Locking is the process by which a planet's rotation synchronizes with its orbital period, resulting in one side of the planet always facing the host star.

Atmospheric Escape is the process by which a planet's atmosphere is lost over time due to various mechanisms, such as solar wind stripping, hydrodynamic escape, and Jeans escape.

Magmatic Resurfacing is the process by which a planet's surface is resurfaced through volcanic activity, resulting in the formation of new surface features and the modification of existing ones.

Impact Cratering is the process by which a planet's surface is modified by the impact of asteroids, comets, and meteoroids, resulting in the formation of craters and other impact features.

Erosion and Deposition is the process by which a planet's surface is modified by the movement of water, wind, and ice, resulting in the formation of landforms such as valleys, mountains, and deserts.

Tectonic Activity is the process by which a planet's surface is modified by the movement of tectonic plates, resulting in the formation of features such as mountain ranges, rift valleys, and earthquakes.

Weathering is the process by which a planet's surface is modified by the interaction of its atmosphere with its surface, resulting in the formation of features such as soil, caves, and sand dunes.

Space Weathering is the process by which a planet's surface is modified by the interaction of its magnetic field with its atmosphere, resulting in the formation of features such as auroras and magnetic anomalies.
