Three days and another year begins.
At about 0.021 astronomical units from its star, b completes an orbit in just over three Earth days. The star is much fainter than Sol, but this remains the innermost of its known planets. The orbit diagram is a schematic: its spacing and the displayed planetary position are not a live view of the system.
The neighbors help weigh the planet.
The 2025 study includes mutual gravitational interactions rather than treating the planets as independent Keplerian signals. This constrains the orbital inclination and gives a dynamical mass near 1.11 Earth masses for b. The result depends on the adopted interacting model; it is not a transit radius or an atmospheric measurement.
An Earth-scale mass leaves room for surprises.
Mass alone does not determine radius, density or surface gravity. The charcoal rocks shown here select a possible rocky, airless world for illustration. Neither an impact basin nor a cliff has been mapped on the real planet. A different interior or atmospheric history could produce a view unlike any of these scenes.
A landscape is not a weather report.
Starlight supplies energy while atmospheric composition, clouds and reflectivity affect how a planet absorbs and releases it. The black sky in these images is an artistic assumption. It cannot establish atmospheric loss, a measured temperature or the presence or absence of a habitat.
