He was on to a brilliant idea about how parallax can be used to estimate some astronomical distances.
Galileo was unable to resolve the rings of Saturn as individual objects with his telescope. They appeared to him as "ears" or handles attached to the planet. The true nature of Saturn's rings was not understood until later observations with more powerful telescopes.
Galileo Galilei was born in Pisa, Italy, in 1564, so he was Italian.
The Parallax View was created on 1974-06-14.
He reasoned that since parallax could not be observed for celestial objects near the sun, then the earth was stationary. This erroneous assumption was because at the time he had no way of knowing that celestial objects were so far away that their parallax angles were too small to detect.He reasoned that since parallax could not be observed for celestial objects near the sun, then the earth was stationary.

I had the same question
You have to ask yourself what is an advantage when parallax measurements are being made? . . parallax happens when you move to a different place and the object you see look a little different, the closest ones appear to have moved more than the ones that are further away. In astronomy parallax is created when the Earth is in opposite points of its orbit. Stars that are close appear to have moved a little, relative to the mass of stars that are a long distance away. Parallax was not observed before the 19th century, and the lack of parallax was always used to 'prove' that the Earth could not possibly be going round the Sun. It was only in the 19th century that parallax was observed, but it was only very tiny movements of the closest stars. It forced people to realise that the stars are incredibly far away and the Earth does go round the Sun after all, so it was extra evidence of the Sun being at the centre of the solar system. A parallax measurement is easier to make if the baseline is longer, so the answer to your question is that Mercury and Venus have no advantage for making parallax measurements.
The Jovian moons. Galileo had little evidence for the heliocentric theory, which was later (in the 18th century) generally accepted as correct after the laws of motion and the law of gravity showed that the Sun is by far the most massive object in the solar system and therefore must be at the centre. Galileo did not have the other major piece of evidence supporting the heliocentric theory, which is the parallax shown by relatively close stars as the Earth moves round its orbit. Parallax is extremely small and was impossible to observe in Galileo's time, and this was used to support the idea that the Earth is at the centre. Bessel made the first measurements of parallax in the 19th century.

parallax is a planet
Galileo I am not so sure he was the first, but he is the most famous.
they look at the star in, say, spring, then fall or summer then winter. we have to be on opposite sides of the star to see the parallax, so it takes about a year
Because Galileo had first contemplated a career in medicine but he didn't like working that job, but he had became interested in mathematics after attending a lecture on geometry. He followed a teaching career that began in Florence and he was later appointed chair of the Mathematics Department at the University of Pisa in 1589.
So Galileo was this really cool guy that had something to deal with space.
Parallax - comics - was created in 1994.
Advent Parallax was created in 2008.
Parallax Software was created in 1993.
Parallax bars are used in photogrammetry and remote sensing. with the use of the principles of parallax and refraction, parallax bars are used to measure the heights of buildings and other features.
