Mashable reporter Elisha Sauers spotlights some of the exoplanets identified thus far in 2025, including BD+05 4868 Ab, a rocky exoplanet discovered by MIT astronomers that has a “comet-like tail stretching more than 5.5 million miles.” BD+05 4868 Ab is “about the size of Mercury and orbits its star every 30.5 hours,” Sauers explains. “At roughly 3,000 degrees Fahrenheit, the planet appears to be shedding material — about one Mount Everest’s worth per orbit — that becomes its tail.”
