Stellar variability strongly affects radial measurements and as a consequence limits the detectability and mass characterisation of low mass planets with radial velocity techniques. After introducing this challenge, I will present the stellar processes affecting radial velocity measurements at various temporal scales and the approach we have developed: we have used our very good knowledge of solar activity to build a large amount of realistic synthetic time series for other solar-type stars. I will show how this approach allowed us to understand better the limitations, leading us to propose a new mitigating method and to estimate the performance of Earth-like planet in the habitable zone detections.
