K2-3d Surface Gravity Compared to Earth

The exact surface gravity of K2-3d is not provided, but with a mass of 2.2 Earths, it would likely have stronger surface gravity compared to Earth.

Surface Temperature of K2-3d

K2-3d has an equilibrium temperature of 305 K (32 °C; 89 °F). This temperature suggests that it could have a relatively warm climate, potentially suitable for liquid water.

Does K2-3d Have Oxygen

The available information does not specify whether K2-3d has oxygen. Determining the composition of an exoplanet's atmosphere typically requires direct observational data.

Is K2-3d Habitable

K2-3d is located in the inner (empirical) habitable zone of its star, K2-3. However, it is likely tidally locked, with extreme temperatures on the illuminated and dark sides. The terminator line, where temperatures may be moderate, could be a potential area for habitability. However, the high stellar flux could lead to surface temperatures making it likely too hot for habitation.

K2-3d Atmosphere Composition

The specific composition of K2-3d's atmosphere is not provided. Observations using next-generation telescopes, such as the James Webb Space Telescope, are expected to analyze its atmosphere for potential signs of life or habitability.

K2-3d Distance from Earth in Light Years

K2-3d is located approximately 147 light-years away from Earth in the constellation of Leo.
