Transmission Spectroscopy Metric for currently known planets, which can be observed with the JWST NIRSpec/Prism. The sample is limited to those with equilibrium temperatures below 500 K and radii smaller than 2.5 R_⊕. The color code refers to the planet’s temperature. Planets with larger TSM than TOI-2096 b and c, are labeled and highlighted with a central dot for quick recognition. TOI-2096 b and c are labeled and highlighted with a cross. Data were taken from NASA Exo-planet Archive on October 24, 2022.
