The object was known to have extended emission pointing away from $\\theta^{1}$ Ori C, indicating ongoing external photoevaporation. Our near-infrared spectroscopic data suggests that the central source of Proplyd 133-353 is substellar ($\\sim$M9.5), might have a mass probably less than 13 Jupiter mass and an age younger than 0.5 Myr.
