  We present the detailed fundamental stellar parameters of the close visual
binary system; HD39438 for the first time. We used Al-Wardat's method for
analyzing binary and multiple stellar systems (BMSSs). The method implements
Kurucz's plane parallel model atmospheres to construct synthetic spectral
energy distributions for both components of the system. It then combines the
results of the spectroscopic analysis with the photometric analysis and then
compares them with the observed ones to construct the best synthetic spectral
energy distributions for the combined system. The analysis gives the precise
fundamental parameters of the individual components of the system. Based on the
positions of the components of HD39438 on the H-R diagram, and evolutionary and
isochrones tracks, we found that the system belongs to the main sequence stars
with masses of 1.24 and 0.98 solar masses for the components A and B,
respectively, and age of 1.995 Gyr for both components. The main result of
HD39438 is new dynamical parallax, which is estimated to be 16.689+- 0.03 mas.
