Question

Quizplus · Accepted Answer

All of these objects have been detected around nearby stars. Comets and asteroids are found in other star systems, often inferred through their effects on starlight or from direct imaging. Terrestrial planets have been discovered through various methods such as the transit method, where the planet passes in front of its star from our viewpoint, dimming the star's light slightly, and the radial velocity method, where the gravitational pull of a planet causes its star to wobble slightly.
