We all know that the highest mountain on the planet is Mount Everest, which is beyond doubt.
What is to be said here is that the highest mountain that humans have explored so far is the Olympus volcano on Mars.
The Olympus volcano has more than 25,000 meters, almost three times the height of Mount Everest. The Olympus volcano has a diameter of 624 kilometers and is the same size as the Korean peninsula. The crater on the top of the mountain is about 72,000 meters wide and 3,000 meters deep. It is the highest peak in the entire solar system.
