Photometric follow-ups of a transiting exoplanet may lead to discovery of another lowmassbody in a System. This is possible by detecting and then analysing variations intransit timing of the transiting exoplanet. We observed transit timing of exoplanet WASPlObwhich cannot be explained by a constant period but by a periodic Variation. Modelsassuming the existence of a perturbing planet in the System and reproducing the observedvariations of timing residuals are considered. As different planet configurations generatesimilar TTV Signals with the identical dominant periodicity, we intend to collect highprecisionobservations in critical phases of observed timing Variation to partially remove thedegeneracy and to point out the most probable planet configuration of WASP-10 System.
