As we know, the exoplanets are mostly detected by the methods of radial velocity and transit, up to now only one is found by the astrometric method. As the data of the gaia will be soon released, As we know, the exoplanets are mostly detected by the methods of radial velocity and transit, up to now only one is found by the astrometric method. As the data of the gaia will be soon released, astrometry will gradually become one of the most important methods for detecting exoplanets.

Astrometry is the oldest search method for extrasolar planets, and was originally popular because of its success in characterizing astrometric binary star systems. It dates back at least to statements made by William Herschel in the late 18th century.

As early as 1943 astronomer Kaj Strand, working at the Sproul Observatory at Swarthmore College announced that his astrometric measurements revealed the presence of a planet orbiting the star 61 Cygni. Although the announcement was greeted with enthusiasm at the time, the claim Astrometry is the branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies. The information obtained by astrometric measurements provides information on the kinematics and physical origin of the Solar System and our galaxy, the Milky Way .

2016-04-10 · The astrometric method relies on measuring the side-to-side movement of a star as it orbits about its center of gravity with another large planet. Though this movement may be too small for most telescopes to detect, the GAIA mission would be able to detect changes of up to 10 microarcseconds.

After this step, all objects in your Astrometrica image will have precise celestial coordinates (right ascension = RA and declination = DEC). This helps you to measure the position of objects on the sky. Briefly describe the astrometric method. the astrometric technique watches for tiny movements of a star against the background of other stars. It's best for detecting massive planets that orbit far from their stars, even though distant planets take longer to orbit. Current technology limits its use to very rare cases.
