Detailed explanation-1: -Galileo Galilei’s observations that Venus appeared in phases–similar to those of Earth’s Moon–in our sky was evidence that Venus orbited the sun and contributed to the downfall of the centuries-old belief that the sun and planets revolved around Earth.
Detailed explanation-2: -Galileo turned his gaze toward Venus, the brightest celestial object in the sky-other than the Sun and the Moon. With his observations of the phases of Venus, Galileo was able to figure out that the planet orbits the Sun, not the Earth as was the common belief in his time.
Detailed explanation-3: -Galileo was the first to observe the phases of Venus. He argued that the fact it exhibits a gibeous phase proves that it orbits the Sun and not the Earth. When Venus is closest to the Earth it is in its new phase and cannot be seen.
Detailed explanation-4: -Galileo concluded that Venus must travel around the Sun, passing at times behind and beyond it, rather than revolving directly around the Earth. Galileo’s observations of the phases of Venus virtually proved that the Earth was not the center of the universe.
