Ptolemy

1. Yes, it would be!
2. And
3. No it wouldn't at the same time!

Both Ptolemy and Copernicus used the circle as the basic element of the orbits, but they both knew that a simple circle was not correct in describing the movements of the planets accurately.

The way they worked round the problem was to use epicycles. An epicycle was a small circle whose centre moved round the main circle, and the planet remained stationary on the epicycle. In other words the line joining the planet to the centre of the epicycle stays in the same direction all the time. This is actually a good approximation to an elliptical orbit because it reproduces the effect of the planet moving closer and further away once during one revolution, and geometrically it is equivalent to having the planet going round a circle but with the Sun offset from the centre (by a different amount for each planet).

That is why the model lasted for as long as it did - 1500 years, until Tycho Brahe made observations and recorded the planets' positions with such high accuracy that Kepler was able to deduce the ellipse as the more correct form for planets' orbits. He did this by studying Tycho's measurements of the orbit of Mars, which has a higher eccentricity factor than all the main planets except Mercury which is difficult to observe, and there was just enough difference for Kepler to spot it.

The major difference between Ptolemy's model and Copernicus's was that the Earth was at the centre when the Ancient Greeks studied the problem, and the Sun had an orbit, while Copernicus in the early 16th century imagined the Sun at the centre. Later scientific discoveries by Newton and his successors demonstrated the sun-centred theory as superior.

Oh, there's a little mix-up there, friend. Ptolemy was actually an ancient astronomer from Egypt, known for his work on the movement of planets. Moon rocks found by astronauts are usually named based on where they were collected, like the famous samples from the Apollo missions. It's wonderful to be curious about space exploration!

Ptolemy V built his tomb during the 2nd century BC in Egypt. The tomb was constructed in the city of Alexandria, following traditional Egyptian burial practices for pharaohs of that era.

They used limestone for most of their pyramids and mostly pure brute strength to carry the limestone.

He suggested that the Indian Ocean was landlocked, which was debunked later by the map made by the Venetian Fra Mauro in 1459.

Yes, Copernicus' heliocentric model of the solar system, with the Sun at the center, provided more accurate predictions of planetary movements compared to Ptolemy's geocentric model, which had the Earth at the center. This was due to the simplicity and elegance of Copernicus' model, leading to a better understanding of the true nature of the solar system.

Ptolemy believes that the earth is the center of the universe.

As a person's name, Ptolemy is a proper noun.
