We present the spectral appearance of Earth-like exoplanets in the habitable zone of different main sequence (F, K and G-type) stars and their spectral response to small orbital distance variations. Using atmospheric profiles from a 1D atmosphere model, we compute transmission and emission spectra in the infrared using a cloud-free line-by-line radiative transfermodel. The orbital distanceswere chosen such that surface temperatures in the atmosphericmodel are in the range of 273K (outer run) to 303K (inner run). The spectra are then analyzed in light of current and future space telescopes like the JamesWebb Telescope (JWST), Spitzer and the ground based European Extremely Large Telescope (E-ELT) in order to discuss the measurability of certain spectral features.
