Astrometric method: Must detect very small wavy motion of the star along its path (milli- or even micro- arcseconds) in the sky. All of them rely on detecting a planet's effect on its parent star, to infer the planet's existence. Current technology limits its use to very rare cases. Astrometry is now one of many fields of research within astronomy. Found tons of planets orbiting stars like our system. ANSWER: Correct Part B Select the planetary properties which we can measure with current astrometric method. Transits within our solar system can be observed from Earth when Venus or Mercury travel between us and the Sun. 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 They formed father out like Jupiter and then migrated inward. Kepler 6b photometry. For . The Doppler technique can be used to obtain the orbital period, orbital distance, the orbital shape and the minimum mass of the planet.
