If true, this might predate Galileo's discovery by around two millennia. [9] The observations of Simon Marius are another noted example of observation, and he later reported observing the moons in 1609. [10] However, because he did not publish these findings until after Galileo, there is a degree of uncertainty around his records. [10]
Italian polymath Galileo Galilei was an early user and made prolific discoveries, including the phases of Venus, which definitively disproved the arrangement of spheres in the Ptolemaic system. Galileo also discovered that the Moon was cratered, that the Sun was marked with sunspots, and that Jupiter had four satellites in orbit around it. [13]
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The discoveries of Io and the other Galilean satellites of Jupiter were published in Galileo's Sidereus Nuncius in March 1610. [1] While the Jovian moons he discovered would later be known as the Galilean satellites, after himself, he proposed the name Medicea Sidera (Medicean Stars) after his new patrons, the de'Medici family of his native ...

1632 – Galileo Galilei is sometimes credited with the discovery of the lunar libration in latitude, [86] although Thomas Harriot or William Gilbert might have done so before.
