The Iron-Rich Basaltic Plains and Red Dawn of Kepler-1649c
Located approximately 301 light-years from Earth in the northern constellation of Cygnus , the rocky exoplanet Kepler-1649c stands as one of the most compelling targets in modern observational astronomy. Discovered through rigorous re-analysis of data from the Kepler Space Telescope's primary mission, this terrestrial world orbits a dim M-dwarf star , Kepler-1649 . With a physical radius measured at 1.06 times that of Earth, Kepler-1649c receives approximately 75 percent of the stellar flux that Earth absorbs from the Sun. This puts the planet in a temperate energy regime, but its actual surface conditions are dictated by an extreme orbital configuration: it is tidally locked . Orbital Synchronization and Gravitational Mechanics Kepler-1649c orbits its parent star at a mere fraction of the distance between Earth and the Sun—approximately 0.079 astronomical units. At this close proximity, the gravitational gradient across the planet's diameter is immense. Over millions of ...
