We report the discovery that the nearby ($\sim$ 6 pc) photometrically variable T2.5 dwarf SIMP~J013656.5+093347 is a likely member of the $\sim$ 200 Myr-old Carina-Near moving group with a probability of $>$ 99.9% based on its full kinematics. Our $v\sin i$ measurement of $50.9 \pm 0.8$ km s$^{-1}$ combined with the known rotation period inferred from variability measurements provide a lower limit of $1.01 \pm 0.02$ $R_{\mathrm{Jup}}$ on the radius of SIMP0136+0933, an independent verification…
