Astrometry is the method that detects the motion of a star by making precise measurements of its position on the sky. As a result of their mutual orbits around the system's center of mass, it was also used to find extrasolar planets through measuring the shift with in parent star's apparent location in the sky that they produce. Which planetary properties we can measure using astrometric method? 3. Since the astrometric method measures two components of the stars motion (x and y in the plane of the sky), it has the potential of determining all orbital parameters and the true mass of the planet. Tom's method is very simple.

What properties of extrasolar planets can we measure? If this is a periodic occurrence we can infer . A transit occurs when a planet passes between a star and its observer. Tom Suiter. If a planet crosses in front of its parent star's disk, then the observed visual brightness of the star drops by a small amount, depending on the relative sizes of the star and the planet.For example, in the case of HD 209458, the star dims by 1.7%. It also can be performed from the ground with quite small telescopes; the TRAPPIST telescopes only have 60 . We can use the small angle equation to calculate that this would be visible as 0.01 seconds of arc from a neighboring star system.
