    I've been using Stellarium for over ten years, it's a quite realistic virtual planetarium.

    It still needs to be set up with your own coordinates. These can be chosen or input in 'Location'.

    It is quite customisable.

    The screenshots above show an older version of Stellarium on my laptop which runs the Ubuntu operating system.

    I'm having another go at reading Patrick moores book called teach yourself astronomy. im reading the chapter about early astronomy, the book has a section of things to remember from that chapter. Here is what i've got,

    Astronomy goes back to our cave dwelling ancestors
    Originally it was thought that the earth was flat and motionless
    Constellation patterns date back to around 3000 BC
    True astronomy began with the Greeks
    Ptolemaic system - Earth lay at the centre of the Universe, with the Moon, Sun, planets and stars moving around it.
    Stagnation after Ptolemy’s death – Dark ages
    Revival of Astronomy due to Arabs in the ninth century
    1543 AD – Copernicus stated that the Sun not Earth should be at the center of the system
    140BC – Hipparchus of Nicaea discovered Precession
    240BC - Eratosthenes made an accurate estimation of the Earths size
    Seventeenth century, the German mathematician Johannes Kepler published his three Laws of Planetary Motion,

    Ptolemaic system involves epicycles, what do epicycles illustrate, do they show the planets retrograde motion?
