Radial Velocity Method The vast majority of exoplanets were discovered through the gravity force they exert on their parent star . In other words they make their stars 'wobble' about as the star-planet system circles around a common centre-of-mass.

The Exoplanet Detection: Radial Velocity Method model simulates the detection of exoplanets by using the radial velocity method and the Doppler effect. In this simulation the exoplanet orbits the star (sun-sized) in circular motion via Kepler's third law. The radial velocity of the star is determined from the velocity of the exoplanet. This animation shows how astronomers use very precise spectrographs such as the HARPS instrument on the 3.6-meter telescope at La Silla, Chile to find exopla Other methods of finding exoplanets include radial velocity (looking for a “wobble” in a star's position caused by a planet’s gravity), direct imaging (blocking the light of the star to see the planet) and microlensing (watching for events where a star passes in front of another star, and the gravity of the first star acts as a lens).

Its lone planet was discovered in by the radial velocity method, like several other exoplanets in the constellation. The method ESO planet finders use, radial velocity method, accounts for most står för merparten av de exoplanetupptäckter som gjorts hittills. It's the third-closest exoplanet discovered with this method. Another is to assess how a star's radial velocity changes, which happens when a  3 Exoplaneter Exoplanet: Planet utanför vårt eget solsystem, vanligtvis i 10 Fotometriska metoden Fotometriska metoden (eng. transit method): Om planeten  Though it has a similar mass to the Sun—1.

One well-known method for detecting the presence of exoplanets is the radial velocity method. On this (radial velocity) method astronomers basically measure the variations in the radial velocity (rate of change of the distance between the object/source and a given point) of the star with respect to Earth.

Astronomers have several methods to calculate stellar distances; when searching for exoplanets, only the nearest stars are searched, and in this case, the parallax method is the most simple and effective. Radial velocity: As an exoplanet orbits a star, the star moves in a small orbit around the system's barycenter or common center of gravity. This results in variations in the speed with which the star moves toward or away from an observer on Earth, causing displacement - red or blue shifting - of absorption lines in its spectrum.

An extrasolar planet (or exoplanet) is a natural planet in a planetary system Advantages: The Radial Velocity method was the first successful 

Another method used by astronomers is the transit technique, which detects the drop in brightness of the host star when a planet passes in front of it. Radial Velocity Method Also called the RV method, it has been the most successful technique used to date. Michel Mayor and Didier Queloz found the first acknowledged exoplanet using this method in 1995. Radial velocity has found 810 exoplanets, the second most after the transit method.
