The recorded orbit
The selected archive solution gives an orbital period of 95.8528 days, or 0.262431 Earth years. Its reported semimajor axis is 0.3715 AU. That orbital scale is 0.959705 times Mercury's semimajor axis. The listed eccentricity is 0.3125. Using those central values, the model's nearest and farthest star–planet distances are about 0.255406 and 0.487594 AU. These are derived comparisons, without propagated errors. The period measures a year on this planet. It does not establish the length of its rotation or the duration of daylight.
Read how orbital period, size, and eccentricity fit together.
Size and mass
The radius parameter is 7.35 (+0.18 / −0.18) Earth radii. Radius describes size; it does not specify the mass or the atmospheric composition. The mass parameter is 58.3 (+1.9 / −1.9) Earth masses. Its archive provenance is Mass. The source lists a bulk-density parameter of 0.81 (+0.15 / −0.15) g/cm³. Different interior mixtures can overlap in density; the value does not identify a unique surface.
The host star and received light
The host is cataloged as TOI-2134. The selected row gives spectral type K5 V. Its reported effective temperature is 4580 K. Its reported radius is 0.709 solar radii. Its reported mass is 0.744 solar masses. The planet's incident-flux parameter is 1.4 (+0.4 / −0.4) times Earth's received stellar flux. The equilibrium-temperature entry is 302 (+19 / −19) K. This is a model quantity, not a measured surface temperature. The available stellar and orbital entries do not establish a breathable atmosphere, surface water, or life.
