What was the importance of the discovery of the gallilean moons in ralationship to the heliocentric theory?

Because they were clearly going around Jupiter, and not the Earth. Everything else could be explained as orbiting Earth (with some finagling in the form of the occasional epicycle to explain retrograde motion), but if the Galilean moons were orbiting Earth, they would have had to have been doing so in an orbit that was nothing but epicycles. It was far simpler to assume that they orbited Jupiter, period, which in fact they do.
If something out there was clearly orbiting a body other than the Earth, then that calls the whole epicycle house of cards into question, because if you assume that the planets orbit the Sun instead of the Earth, you don't need epicycles any more; it's much more elegant mathematically. You can still, if you like, assume the Earth is "special" and that the Sun orbits it (which, in fact, some people did, Tycho Brahe being one), though the heliocentric approach was a little more consistent.

His observation that something (Jupiter's moons) clearly and unambiguously orbited something other than the Earth was a stinging rebuke of the geocentric theory. In and of itself, it didn't prove that the heliocentric theory was right or wrong, it just proved that some things didn't orbit the Earth which paved the way for asking if anything really did orbit the Earth (the Moon does; other than that, no).

Wiki User

revolution.

more believable.

How often do solar eclipses occur on Jupiter?
Quite often as Jupiter has at least 63 moons including the 4 large Gallilean moons.
What did Galileo galilei study?
Galileo studied many heavenly bodies including the sun, which damaged his eyesight but he is most famous for studying Jupiter and it's four largest moons - Ganymede, Io, Europa and Callisto. Which are nowadays known as "The Gallilean Moons"
What planets do you need a telescope to see?
Technically, you can see every planet right up to Pluto (Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune). The last two are of course much tougher to find, since they aren't visible to the naked eye. The other 5 planets can be seen with the eye, so you will obviously be able to see them magnified slightly. If you bought a decently cheap telescope, you SHOULD be able to see Jupiter's Satellite system (the Gallilean moons) and Saturn's rings. Mars is pretty boring in tiny telescopes, and Venus displays some detail.
What planet has a gallilean moon with ice volcanoes?
The planet is Jupiter

What are the uses of the concave lens?
Uses of Concave LensesConcave lenses are used to make objects look smaller.
Are Io Europa Ganymede Callisto Jupiter's main moons?
yes.actually Jupiter has many moons. of these,io,europa,ganymede and callisto are the largest and the main ones.... They are also called the Gallilean satellites, after their discoverer.
What languages did the 12 apostles speak?
Jesus most likely spoke Aramaic in a Gallilean dialect. Most of his lifetime was spent in Gallilean speaking areas. The apostles wrote in Aramiac so that people could have their stories in the same language after they were gone. Later writings in the Bible were in Hebrew. There is a controversy as to whether the early versions were written in or translated to Greek, but the early Church scholars say the translations came later. "Eusebius himself declared that "Matthew had begun by preaching to the Hebrews, and when he made up his mind to go to others too, he committed his own Gospel to writing in his native tongue [Aramaic], so that for those with whom he was no longer present the gap left by his departure was filled by what he wrote" (History of the Church 3:24 [inter 300-325])."
How do you make a simple telescope?
You can assemble a simple telescope by using two lenses, one weak convex lens (this is thicker at the centre) as the objective and a stronger concave lens ( thinner at the centre) as the eyepiece. then, with simple manipulation you can determine the focal length of your lenses, double this calculation for length of tubing required to mount lenses and assemble a gallilean style telescope. ******* An online visual guide can help you understand what is involved in building a telescope.
How do you build a telescope?
There are two types of telescopes, Gallilean or Reflective. What you need depends upon the type. Lenses are the key things for both types, with a large concave mirror (three inches or more) for the reflective. Grinding your own mirror can be a time consuming task taking hours, but much cheaper than buying one. It is just a matter of lining up the lenses with the proper distances to create one. Estes Scientific used to sell kits to make your own. ****** An online visual guide gives you an idea of what is involved. see www.howtelescopeswork.com
What was the food like in Galilee at the time of Jesus?
bread, berries, grain, vegetables and meat. however Jews were not permitted to eat the meat of any creatures without hoofs or hoofs that split feet i.e pigs, birds bats, rodents. Jews were not permitted to eat any meat that had been cooked with blood or anymeat with blood still in it. they were not permitted to eat the meat of any creature that had been offered as a sacrifice. Jews also would not eat unleaven bread (bread cooked without yeast) on the sabbath day or on religious days of the year. fish was also a very common food.
