Official catalogue designation: Kepler-186 f
Your name for it: Planet Brenda
An Earth-sized world near the outer part of its red dwarf’s habitable zone. Its size and orbit are known; its atmosphere, surface and actual living conditions remain open questions.

Values are rounded from published catalogue measurements. Sky coordinates identify the host system, not a resolved planetary surface.
A milestone in the search
Announced in 2014, Kepler-186 f was the first validated Earth-sized planet found in another star’s habitable zone. Its radius is about 1.17 times Earth’s. Similar size does not establish an Earth-like environment.
What habitable zone actually means
The term describes a range of stellar illumination where liquid surface water could be possible under suitable atmospheric conditions. It is not a detection of water, a climate measurement or a statement that anyone lives there.
A quieter kind of year
The planet takes about 129.9 days to orbit its M-type red dwarf. The host system lies in Cygnus, roughly 580 light-years away using the NASA archive’s current distance estimate.
The gaps in our knowledge
There is no confirmed surface map or atmosphere for this planet. Its mass has not been directly measured; model estimates based on radius should not be mistaken for a weighed world. The print keeps to the measured size and orbital information.
A deliberately restrained imagining
We have chosen a cool mineral globe, angled illumination and quiet space around it. Rock textures, a faint limb and the muted palette are artistic choices representing one possible appearance. They do not imply oceans, life or a measured atmosphere.
Your name. Its proper designation.
A personal dedication shares the print with Kepler-186 f’s scientific identity. The gift records a commemorative naming, leaving the research catalogues and any hypothetical inhabitants entirely undisturbed.
