I WONDER - Can You See The Planet Mercury From Earth?

Mercury can be seen with the naked eye under clear conditions, but not when it's near the sun. It is visible in the western sky before sunset and in the eastern sky before sunrise. Mercury's thin atmosphere, extreme temperatures, and large craters make it uninhabitable. Although humans are unlikely to visit, a meteorite found on Earth in 2012 matched data from NASA's Messenger probe, indicating its origin from Mercury.

What was discovered on Earth in 2012 that relates to Mercury?

How does NASA's messenger probe relate to our understanding of Mercury?
