Astronomers say a distant world called HD 137010 b could sit on the edge of habitability despite its icy temperatures.

When people picture a potentially habitable planet, they imagine something warm and comfortably orbiting a star like our Sun. But researchers studying HD 137010 b are challenging that assumption in an intriguing way.
Located about 146 light-years from Earth, this exoplanet candidate appears to orbit a cooler, dimmer K-type star. It’s roughly Earth-sized and completes one orbit in about 355 days.
Although its estimated surface temperature is far colder than Earth’s, scientists say its position near the outer edge of the habitable zone means liquid water might still be possible under the right atmospheric conditions.
