Alas, later evidence suggested his conclusions were incorrect, but I learned a great deal about the subject, as well as about the scientific method, by studying what this impressive astronomer had accomplished. In gravitational microlensing, scientists watch what happens while a large object passes in the front of a star from our attitude on Earth. There are millions of planetary systems in our galaxy, of which the Drake Equation estimates there may be around 10 000 with intelligent life. This may seem surprising, as the Sun is one of about 200 billion stars (or perhaps more) just in the Milky Way galaxy alone. Favourite answer. With all those other stars, why haven't scientists studied other solar systems, at least enough to know how many are in our galaxy? According to the scientists, there may be tens of billions of solar systems in our galaxy, perhaps even as many as 100 billion. Venus takes 224.7 Earth days to revolve around the sun. With new technology, solar systems are slowly being found now. Kepler employs the transit approach, which watches for the tiny, telltale dips in a star's brightness triggered while a planet crosses the star's face, blockading a number of its light. 30 Answers.
