In this study, light curve of LT Aur eclipsing binary star system obtained from Transiting Exoplanet Survey Satellite (TESS) observations is solved for the first time. In addition, orbital period analysis of the system is also presented for the first time. As a result of the light curve analysis, it is concluded that LT Aur is a semi-detached binary star system. Using the light curve solution parameters, the absolute parameters of the system are estimated as , , . Orbital period analysis of LT Aur shows that the orbital period of the system is increasing regularly at a rate of 1.310±0.253 s/year. Considering that this increase in the orbital period may be due to a dominant mass transfer mechanism from the low-mass secondary component to the high-mass primary component, the mass transfer rate onto the primary component is estimated to be between /year and /year.
