TESS discovers a planet the size of Mars but with the makeup of Mercury
Ultra-short-period planets are small, compact worlds that whip around their stars at close range, completing an orbit - and a single, scorching year - in less than 24 hours. How these planets came to be in such extreme configurations is one of the continuing mysteries of exoplanetary science.
Now, astronomers have discovered an ultra-short-period planet (USP) that is also super light. The India’s Chandrayaan-2 maneuvered to avoid close approach to NASA’s Lunar Reconnaissance Orbiter
