Galileo discovered, in his observations of the different phases of Venus, that Venus and the Earth were revolving around the Sun. This was contrary to the misconception at the time that everything revolved around the Earth.
He did not discover the planet Jupiter. He only used his telescope to see its four largest moons. The planet is and always has been visible to the naked eye and was known to people since ancient times.
Galileo Galilei first recorded phases in Venus in 1610, and published his findings in 1613.
no
Galileo Galilei
Gallieo Galilei first observed that Venus has phases. This is due, primarily, to the fact that Venus is closer to the Sun than the Earth is. In order to display phases, particularly crescent phases, the observed object must be closer to the Sun than the observer.
No. He discovered the phases of venus.
Well yes and no. The phases of the moon were understood well before Galileo --- however Galileo discovered the moons of Jupiter and no doubt their associated phases --- as well as the phases of Venus.
The phases of the planet Venus are the different variations of lighting seen on the planet's surface
Galileo discovered sunspots in 1612. He also discovered the phases of Venus and four of Jupiter's moons during his lifetime.

No, Venus was already known of in Galileo's time.
