多普勒光谱学是第一个用来揭示太阳系外行星系统的存在的技术。径向速度测量发现了大量的超级地球和海王星类行星。大量检测到的系统显示出显著的多样性。将多普勒测量与行星凌日的光度观测相结合，进一步提供了行星体积密度的途径，这是比较系外行星学的第一步。新型高精度光谱仪和天基设施的发展将最终使我们能够描绘出我们近邻恒星可居住区内的岩石行星的特征。
Doppler spectroscopy was the first technique used to reveal the existence of extrasolar planetary systems hosted by solar-type stars. Radial-velocity surveys led to the detection of a rich population of super-Earths and Neptune-type planets. The numerous detected systems revealed a remarkable diversity. Combining Doppler measurements with photometric observations of planets transiting their host stars further provides access to the planet bulk density, a first step towards comparative exoplanetology. The development of new high-precision spectrographs and space-based facilities will ultimately lead us to characterize rocky planets in the habitable zone of our close stellar neighbours.
