The Dynamical Environment Within the Habitable Zone of the Gaia-4 and Gaia-5 Planetary Systems
Stephen R. Kane 2025 AJ 170 329 The known planets in the Gaia-4 and Gaia-5 systems mostly exclude the possibility of planets in the habitable zones of these stars; giant planets on eccentric orbits…

In November 2025, UC Irvine astronomers announced a rocky super-Earth called GJ 251 c orbiting in a habitable zone less than 20 light-years away — close enough that the next generation of ground-based telescopes may actually photograph it directly
GJ 251 c is the kind of planet astronomers have been trying to find for decades: nearby, relatively small, in a temperate orbit, and separat
