Uranus   

Uranus themes are Liberation and Freedom - "de- and re-programming for evolution". He activates, ignites and he's electrical (seizures). He likes surprises and those most ideally sudden - it's his instrument for radical change. He's the least selfish of all the planets and very intelligent (air energy) with a scientific mind. When we can liberate ourselves from restrictive thinking, to allow our "comfort" to be challenged by change, we may open the door for surprises and wonders to enter our lives.... and that is, what he talks about... 

Greek Mythology: Uranus (a Titan) is the God of the Sky. He's married to Gaia. Cronus (Saturn) is their Son and Zeus (Jupiter) their Grandson. In the story, it's Saturn who "castrates" Uranus as he didn't wont to give over the "throne" - out of the semen, that fell into the sea, Aphrodite (Venus) was born.... 
A thought note: Uranus is ruler of Aquarius, an age shift to Capricorn occurred and made Saturn the new ruler, as then, the precession of the equinoxes moved on and a shift into Sagittarius occurred (as predicted by Uranus to Saturn), his son Zeus (Jupiter) took on the throne....  This means we're now "ruled" by Poseidon (Neptune) who travels through Aquarius for a while already, which will be the next age and the "throne" would go back to Uranus....

Some Astronomy:  Uranus was "discovered" in 1781 by William Herschel northeast of the star Zeta Tauri and deeply observed and studied by Astronomer Johann Elert Bode, who also suggested the name. In around 2030 he'll return to this discovery location.
Uranus got 27 moons so far discovered. - He's about 4 times the size of Earth.
Uranus orbits the Sun once every 84 years, taking an average of seven years to pass through each constellation of the zodiac - he rotates once around himself within 17 hours from east to west, as also Venus does but he looks as rotating on the side - The Uranian axis of rotation is approximately parallel with the plane of the Solar System, with an axial tilt of 97.77° (as defined by prograde rotation).
Uranus got several rings (like Saturn) but his magnetic field is much stronger than that of Saturn.
The axial tilt and rotation gives Uranus seasonal changes completely unlike those of the other planets. Near the solstice, one pole faces the Sun continuously and the other faces away. Only a narrow strip around the equator experiences a rapid day–night cycle, but with the Sun low over the horizon. At the other side of Uranus's orbit the orientation of the poles towards the Sun is reversed. Each pole gets around 42 years of continuous sunlight, followed by 42 years of darkness. His last equinox was on the 7th of December 2007.
The intensity of sunlight varies inversely with the square of distance, and so on Uranus (at about 20 times the distance from the Sun compared to Earth) it is about 1/400 the intensity of light on Earth.  (Ref. Wikipedia/Nasa)

Hubble captured detailed features of three layers of Uranus' atmosphere.   

Uranus' axis:  (heliocentric 2020)

Southnode: 19°10' Scorpio
Northnode: 19°10' Taurus
Aphelion:     26°42' Aquarius     
Perihelion:   26°42' Leo

His most influence (Perihelion) in Leo, suggests, that the change has to come from the Individual, that influences and changes the Collective
His nodal axis suggests, that he works within, to get the inside out and to define self accordingly....
