In a study published in Monthly Notices of the Royal Astronomical Society, an international team of scientists describes a hellish exoplanet, providing a glimpse into Earth’s distant future.
In analyzing the illumination pattern of the exoplanet K2-141b, the team discovered that about two-thirds of the planet faces perpetual daylight. K2-141b is an Earth-size exoplanet orbiting an orange dwarf – stars which are slightly cooler than our own sun – in the Sagittarius constellation. K2-141b belongs to a subset of rocky planets that orbit very close to their star. The planet needs just six hours to make a full orbit. This proximity keeps the exoplanet gravitationally locked in place, meaning the same side always faces the star.
Based on this observation, the researchers tried to simulate the environmental
