Transit photometry detects an exoplanet when it crosses the face of its star and blocks a measurable fraction of starlight. Transits measure planetary radii, orbital periods, system geometry, atmospheric spectra, and population statistics.

The radial-velocity method detects the line-of-sight motion of a star as it orbits the common center of mass with an unseen planet. Radial velocity measures planetary masses, detects nontransiting planets, constrains eccentricity, and combines with transit radius to derive bulk density.

Direct imaging isolates photons from an exoplanet itself rather than inferring the planet only through its effect on the host star. Direct imaging enables atmospheric characterization and orbital tracking and is a key long-term route toward spectra of smaller temperate planets around nearby stars.

Gravitational microlensing detects planets when a foreground star passes close to the line of sight to a distant background source and its gravity magnifies the source's light. Microlensing samples planets farther from their stars, low-mass worlds, and potentially free-floating planets, complementing detection methods biased toward close-in systems.

Astrometry and transit timing variations detect planets through changes in stellar position or in the timing of other planets rather than through brightness depth or Doppler speed alone. These methods reveal orbital inclination, true planet mass, unseen companions, resonant architecture, and planetary masses in compact multiplanet systems.
