The recorded orbit
The selected archive solution gives an orbital period of 6.02 days, or 0.0164819 Earth years. Its reported semimajor axis is 0.0531 AU. That orbital scale is 0.137175 times Mercury's semimajor axis. 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
No planetary radius is supplied in this selected solution. The profile leaves that gap visible rather than estimating a size from the mass. The mass parameter is 8.4 (+1.3 / −1.3) Earth masses. Its archive provenance is Msini. Read this provenance before comparing it with a true mass: an inclination-dependent minimum or another mass definition must keep its qualification.
The host star and received light
The host is cataloged as Gl 410. Its reported effective temperature is 3842 K. Its reported radius is 0.543 solar radii. Its reported mass is 0.55 solar masses. The available stellar and orbital entries do not establish a breathable atmosphere, surface water, or life.
