It is believed that all of the planets, from Mercury to Neptune, formed around the same time, about 4.95 billion years ago.
Presumably, Mercury is of similar age to Earth.
The only way to be sure, of course, would be to land on the surface and use radioisotope dating to determine the age of the rock. Such a mission is not planned and probably will not be undertaken in the next 25 years.

∙ 12y agoThe planet Mercury spins very slowly, once every 58.646 Earth days. It orbits the Sun very rapidly, once every 88 Earth days. The combination of these motions leads to an unusual situation. The length of a "solar day" (sunrise to sunrise) on Mercury is 176 Earth days, or twice as long as the year.
