  "summary": "Mercury's surface is riddled with wrinkles, evidence of a once-larger planet that has shrunk over time. A new study finds that Mercury may have contracted 10% to 30% more than previously thought—a loss of nearly 12 miles (19 kilometers) of total diameter since the planet formed—due to debris from impact craters obscuring signs of the planet's shrinking.",
