How do we use transits to detect exoplanets? Most known exoplanets have been discovered using the transit method. A transit occurs when a planet passes between a star and its observer. Transits within our solar system can be observed from Earth when Venus or Mercury travel between us and the Sun.
What is the transit method for detecting exoplanets? The transit method is a photometric method that aims to indirectly detect the presence of one or more exoplanets in orbit around a star. In 1999, the method was used to confirm the existence of HD209458b, a planet that had been discovered almost at the same time by the radial velocity method.
Why are transits of exoplanets so useful in determining their properties? Because transiting exoplanets orbit in orbital planes that are necessarily edge-on to Earth-based observers, using both the transit method and the radial-velocity method to observe the same planet can provide the planet’s mass and therefore its density and likely composition.
