Stellar surface inhomogeneities can cause difficulties in detecting and accurately characterizing the planetary systems through spectroscopic and photometric observations. I will discuss how these inhomogeneities can lead to inaccurate estimation of planetary parameters (e.g., the planetary mass, planet's radius, orbital inclination, and spin-orbit angle). I will also talk about how the stellar active regions can affect the transmission spectroscopy’s measurements and how easily can mimic the signature of Rayleigh scattering in the planetary atmosphere.
