课程详情
- Astronomical Unit (AU): The average distance between the Earth and the Sun; a fundamental unit for measuring distances within our solar system and to nearby exoplanets.
- Light Year (ly): The distance light travels in one year; useful for expressing vast distances to more remote exoplanets.
- Parsec (pc): A unit of distance used in astronomy, equal to 3.26 light-years; often used in professional exoplanet research.
- Kepler's Third Law: Relates the orbital period and semi-major axis of an orbiting body (exoplanet); a cornerstone of exoplanet orbital calculations.
- Orbital Period (P): The time it takes an exoplanet to complete one orbit around its star.
- Semi-major Axis (a): Half of the longest diameter of an elliptical orbit; crucial in Kepler's Third Law and determining the exoplanet's distance from its star.
- Eccentricity (e): A measure of how elliptical an orbit is; ranging from 0 (perfectly circular) to 1 (parabolic).
- Exoplanet Transit: The event when an exoplanet passes in front of its star, causing a slight dimming; a common method for detecting exoplanets.
- Radial Velocity: The method of detecting exoplanets by measuring the wobble of the star caused by the gravitational pull of the orbiting planet.
- Stellar Mass (M): The mass of the star around which an exoplanet orbits; essential for accurate Kepler's Third Law calculations.
