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.

Other methods at exoplanet astronomers' disposals include detecting gravitational lensing due to a planet (called the microlensing method), searching for the wobble in the star's position on the sky (called the astrometric method), and separating the light of the star from the planet and actually taking images (called the direct imaging method).

When planet hunters use astrometry, they look for a minute but regular wobble in a star's position compared to the positions of other stars. In observational astronomy, astrometric techniques help identify stellar objects by their unique motions. It is instrumental for keeping time, in that UTC is essentially the atomic time synchronized to Earth 's rotation by means of exact astronomical observations. 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. Abstract 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.

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 . One potential advantage of the astrometric method is that it is most sensitive to planets with large orbits. This makes it complementary to other methods that are most sensitive to planets with small orbits.
