Jupiter is the largest planet of our solar system and is among the five planets visible with naked eye. This makes it difficult to accurately say who discovered the planet as it was seen by people even before the history was recorded. However, Galileo Galilei, an Italian astronomer observed the four moons orbiting the planet in 1610, which were later called Galileo’s Moons and named after the lovers of god Zeus. Galileo is known as the “father of modern observational astronomy”.
