We present the results of the combined spectrophotometric and dynamic analysis for the close visual binary star Hip 42455 (HD 73900, I 314). A model binary that consists of two main sequence stars with a clear magnitude difference, but completely different estimations of their spectral types, and different parallax measurements given by the four catalogs of the two main precise astrometric missions, Hipparcos and Gaia. The analysis follows Al-Wardat's method for analyzing binary and multiple stellar systems. It investigates the system's physical parameters using the parallax measurements given by the catalogs of Hip 1997, Hip 2007, Gaia DR2, and EDR3. The results were as follows: T_eff^A=6880±70 K, Teff^B=5630±70 K, R_A=1.554 R_☉, R_B=0.929 R_☉, M_A=1.44±0.15M _☉, M_B=0.98±0.13M _☉, while the spectral type for the primary and secondary components are G7V and F2V, respectively. As a result, the new parallax for this system was given as π_Dyn=25.82±0.85, based on the best fit between the dynamical mass sum and the individual masses. This value lies between the old (1997) and new (2007) Hipparcos measurements, and is a bit far from those given by Gaia DR2 and Gaia EDR3.
