Exoplanets I have heard that exoplanet Kepler-1625b might have an exomoon. Is it possible for two planets to be in a binary system around a single star?
Solar System Does (or will) the planet Venus get hotter as years and centuries pass, or will it stay at the same temperature?
Solar System Is Jupiter’s moon Io gradually losing mass because of all the volcanic activity? And if so, what will be the moon’s final fate?
