👤 whose
Whose observations first showed that Venus has phases like the Moon?
Quick Answer
Galileo Galilei’s. His telescopic observations of Venus’s phases supported the heliocentric model.
The Full Story
In 1610 and 1611, Galileo observed that Venus goes through a full set of phases, similar to the Moon. This pattern only makes sense if Venus orbits the Sun and not Earth. The finding strongly supported Copernican astronomy against the geocentric model. It became one of the classic early telescopic arguments for heliocentrism.
Key Facts
1.Observed in 1610–1611
