The amount by which the star dims depends on its size and the planet's size, among other factors.\n\nRadial velocity (or Doppler method): As a planet orbits a star, the star also moves in its small orbit around the system's center of mass. Variations in the star's radial velocity\u2014the speed with which it moves towards or away from Earth\u2014can be detected from displacements in the star's spectral lines due to the Doppler effect.\n\nMicrolensing: Microlensing occurs when the gravitational field of a star acts like a lens, magnifying the light of a distant background star. Planets orbiting the lensing star can cause detectable anomalies in the magnification as it varies over time.\n\nDetails on other methods of discovery are available on Wikipedia: https://en.wikipedia.org/wiki/Exoplanet#Detection_methods\n",
