Notes Uranus, was the primal Greek god personifying the sky. His equivalent in Roman mythology was Caelus. In Ancient Greek literature, according to Hesiod in his Theogony, Uranus or Father Sky was the son and husband of Gaia, Mother Earth. The ancient Greeks and Romans knew of only five 'wandering stars': Mercury, Venus, Mars, Jupiter, and Saturn. Following the discovery of a sixth planet in the 18th century, the name Uranus was chosen as the logical addition to the series: for Mars was the son of Jupiter, Jupiter the son of Saturn, and Saturn the son of Uranus.

[1] Apparent Magnitude at Opposition.
[2] The mean distance to the Sun.
[3] Astronomical Units from the sun. One AU is the approximately the mean Earth-Sun distance.
[4] Geometric Albedo.
[5] The Solar orbital period (one year) in earth days.
[6] Orbital inclination with reference to the SUN in degrees.
[7] Tilt of rotainal axis in degrees.
[8] Orbital Eccentricity (The amount by which an orbit deviates from a perfect circle. 0 is perfectly circular, and 1 is a parabola).
[9] Siderial rotational day (Measured relative to the fixed stars) in earth days.
[10] Mean Orbital Velocity (The speed at which it orbits around the planet/ Sun barycenter).

About Me

I am an amateur astronomer; I am interested in science, innovation, astronomy and general musing about philosophies of life, the universe and our place in it.

I love to look up and wonder, and this blog is mostly what results from that wondering.

I also enjoy Paragliding.
