Abstract: This paper presents a multi-wavelength astrophysical characterization of Gaia DR3 3130488240559447296, a stellar source located along the line of sight to the Monoceros R2 star-forming region. Utilizing high-precision astrometry from Gaia DR3, time-series optical photometry from the Zwicky Transient Facility (ZTF), and infrared cross-mapping from 2MASS and AllWISE, we determined the fundamental physical parameters and assessed the photometric stability of the target. Contrary to the volatile Young Stellar Objects (YSOs) typical of the Monoceros R2 environment, kinematic and photometric analyses indicate that the source is a stable, middle-aged G-type main-sequence star. We derived a stellar mass of 1.08 M, a radius of 1.06 R, and a bolometric luminosity of 1.30 L, firmly classifying the target as a solar analogue. Furthermore, the data show no statistically significant intrinsic photometric variability, no infrared excess indicative of a protoplanetary disk, and no evidence of a gravitationally bound binary companion. These findings establish the source as a highly stable, isolated solar-type star, providing a valuable observational baseline for mature stars projected against dense interstellar environments and identifying it as a compelling candidate for future exoplanetary transit surveys.
