Archive retrieved November 1, 2026 (America/New_York). The selected paper and archive update dates appear below.
The recorded orbit
The selected archive solution gives an orbital period of 7.57686 days, or 0.0207443 Earth years. The listed eccentricity is 0. A zero may be a circular assumption fixed in the fit; consult the paper before treating it as an exact observed shape. 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 0.88 (+0.05 / −0.05) Earth radii. Radius describes size; it does not specify the mass or the atmospheric composition. The mass parameter is Upper limit: 4 Earth masses. Its archive provenance is Mass.
The host star and received light
The host is cataloged as GJ 341. The selected row gives spectral type M1. Its reported effective temperature is 3770 K. Its reported radius is 0.5066 solar radii. Its reported mass is 0.48 solar masses. The planet's incident-flux parameter is 13.8 (+5.9 / −3.7) times Earth's received stellar flux. The available stellar and orbital entries do not establish a breathable atmosphere, surface water, or life.
