Exoplanet Detection Methods

The radial velocity method measures the slight wobble of a star caused by the gravitational pull of an orbiting planet.

The transit method detects exoplanets by measuring the slight dimming of a star's light when an exoplanet passes in front of it.

The microlensing method detects exoplanets by measuring the way they bend the light of a background star.

The astrometry method detects exoplanets by measuring the slight wobble of a star caused by the gravitational pull of an orbiting planet.

Microlensing is an indirect method for detecting exoplanets, as it does not directly image the planet.

The radial velocity method is the most sensitive method for detecting exoplanets, and it can detect exoplanets that are not transiting their host star.

The radial velocity method cannot measure the mass of exoplanets, as it only measures the velocity of the star.

The transit method can measure the radius of exoplanets, as it measures the amount of light that is blocked by the planet as it transits its host star.

The transit method can only detect exoplanets that are transiting their host star, as it relies on the planet blocking the light of the star.

The microlensing method can detect exoplanets that are far from their host star, as it does not rely on the planet blocking the light of the star.

The microlensing method is not very sensitive, as it relies on the chance alignment of a star, an exoplanet, and an observer.

The astrometry method can measure the mass of exoplanets, as it measures the amount of wobble that the star experiences due to the gravitational pull of the planet.

The astrometry method is not very sensitive, as it relies on the precise measurement of the position of a star.

The radial velocity method is best suited for detecting small, rocky exoplanets, as it is sensitive to the small changes in a star's velocity caused by the gravitational pull of a planet.

The transit method is best suited for detecting large, gaseous exoplanets, as they block more light from their host star when they transit.
