What Galileo discovered about Venus?
He observed the phases of Venus It was Galileo’s observations of Venus that proved the theory. Using his telescope, Galileo found that Venus went through phases, just like our Moon. But, the nature of these phases could only be explained by Venus going around the Sun, not the Earth.
Did Galileo observe Venus?
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.
When did Galileo find Venus?
October 1610
Galileo made his first telescopic observations of Venus in October 1610. He was excited to see whether Venus showed different phases, like the Moon. Before the invention of the telescope, Venus and the other planets just looked like bright stars.

What does Venus’s name mean?
goddess of love and beauty
Venus, the brightest planet in the night sky, was named after the Roman goddess of love and beauty.
What did Galileo discover about the planet Venus?
Discovery of Venus. Even with his crude telescope, Galileo realized that Venus goes through phases like the Moon. These observations helped support the Copernican view that the planets orbited the Sun, and not the Earth as previously believed. Astronomers predicted that Venus would transit across the surface of the Sun.
Who was the first person to see Venus?
It contains a 21-year record of Venus’ appearances. Venus played a part in the mythology of many ancient peoples, including the Mayans and the Greeks. The first person to point a telescope at Venus was Galileo Galilei in 1610. Even with his crude telescope, Galileo realized that Venus goes through phases like the Moon.
What if Galileo were around today?
Galileo sparked the birth of modern astronomy with his observations of the Moon, phases of Venus, moons around Jupiter, sunspots, and the news that seemingly countless individual stars make up the Milky Way Galaxy. If Galileo were around today, he would surely be amazed at NASA’s exploration of our solar system and beyond.
What did Astronomers predict about Venus in 1639?
Astronomers predicted that Venus would transit across the surface of the Sun. The first time this was observed was on December 4, 1639, and later transits helped astronomers discover that Venus has an atmosphere, and helped calculate the distance from the Earth to the Sun with great accuracy.
