Choose the best description of the transit method of locating exoplanets.
By aiming powerful telescopes directly at star systems astronomers are able to detect larger planets.
Using satellite based telescopes in different locations astronomers are able use parallax calculations to determine if there are planets in orbit around a star.
When a planet passes between a star and an observer the luminosity of the star is reduced by a small amount.
Using a telescope, wobble can be detected from the effect that the planet's gravity has on the star.
