While Nicolas Copernicus is widely credited with developing the idea of the Sun-centered or "heliocentric" model of the solar system, the original idea was published nearly 2000 years earlier by the Greek astronomer and mathematician Aristarchus of Samos.

The "geocentric model" probably doesn't deserve the term "model"; isn't it OBVIOUS, just from being a farmer or shepherd, that the Sun and the Moon rise and set and go around the big flat Earth? Who needs an explanation for THAT!?!
And to be honest, until you are confronted with some alternative explanation, who needs a model? Some things ARE obvious, until you start to examine them closely. it isn't until you start looking at tiny details, like the way that the deck of a ship disappears while the sails are still visible, or that a tall lighthouse is visible further away than a short one, that there might be more to things than are obvious.
Until there was an explanation for the motion of the Sun and the Moon that involved the Earth going around the Sun, there wasn't any need to think of things any other way. And some of the clearest evidence of the "heliocentric model" isn't obvious AT ALL until you start looking at things very precisely.
To the extent that there is somebody who gets the blame (one can hardly give "credit" for an error) for defending the geocentric explanation, that person would probably be Aristotle. Aristotle single-handedly delayed the progress of science, astronomy, Biology and physics by at least a thousand years. If not for Aristotle, we would probably have colonies around the nearer stars by now, and our lives would be immeasurably longer and healthier. Read any of Aristotle's writings; every time he states a "fact", he's wrong, in EVERY particular. Aristotle may have been the "wrongest" man in history!
Copernicus proposed it and Newton developed it by confirming Keplar's laws based on Tycho Brahe's data.
I believe you are confusing two things here; there is no such thing as a "heliocentric model of telescope". There is a heliocentric model of our Solar System, and there are telescopes. The two are unrelated.
Great Britain, in well known for a highly developed civil service system both at home as well as in former British possessions. The East India Company is credited for developing a set of merit based appointments that became the model for the British Civil Service.
Viewed from Earth, Venus is the brightest planet.
The planets Uranus and Neptune were discovered only in modern times after the heliocentric model had been generally accepted.
You can look at the settings menu under system information under system settings. It will let you know the original available memory and the current available memory. You will be able to figure out from the available memory the next highest GB. For instance on my 320 GB model the available memory was 298 GB. The different hard drive sizes are 20,40 60 80 120 160 250 and 320. The related link includes a chart of the hard drive size by model number
