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