    • n Uranus In classical mythology, the son of Ge or Gaia (the Earth), and by her the father of the Titans, Cyclopes, etc. He hated his children, and confined them in Tartarus; but on the instigation of Gaia, Kronos, the youngest of the Titans, overthrew and dethroned him. Also written Ouranos.
    • n Uranus In astronomy, the outermost but one of the planets, appearing to the naked eye as a faint star. It was discovered as a moving body with a disk, March 13th, 1781, by Sir W. Herschel, but had previously been observed twenty times as a star by different observers. These are called the ancient observations of Uranus. The planet, seen with a telescope of the first class, appears as a small bluish disk with two bands. The diameter perpendicular to these is less than that parallel to them by 1/14. It is a little smaller than Neptune, its diameter being 31,000 miles; its mass is 1/22600 of the sun, or 14.7 times

Constraints to Uranus' Great Collision. IV. The Origin of Prospero
In the particular case of Uranus, their existence may cast light on the mechanism responsible for its peculiar rotation axis (Parisi & Brunini 1997, Brunini et al. 2002 (hereafter BP02)).
Several theories to account for the large obliquity of Uranus have been proposed.
In an attempt to clarify the origin of Uranus obliquity and of its irregulars, we are using in this study the most updated information on their orbital and physical properties.
Lissauer & Safronov 1991), the GC is assumed to occur at the end of Uranus formation (e.g.
Assume that the GC occurred when Uranus was almost fully formed, meaning that its feeding zone was already depleted of primordial planetesimals.
Here we report numerical simulations showing that Uranus’ axis can be tilted during the planetary migration, without the need of a giant impact, provided that the planet had an additional satellite and a temporary large inclination.
A collisionless scenario for Uranus tilting
Today, Uranus’ obliquity (97◦ ) is essentially stable.
A collisionless scenario for Uranus tilting
We therefore propose that Uranus had an additional satellite and that its spin-axis was tilted during the planetary migration.
A collisionless scenario for Uranus tilting
The construction of such a scenario for Uranus tilting can be described in four steps.
A collisionless scenario for Uranus tilting
Fig. 1.— Uranus precession frequency in presence of a heavy satellite.
A collisionless scenario for Uranus tilting
Uranus effective precession constant as a function of the distance of an additional satellite of mass m = 0.01 MU (a), m = 0.005 MU (b), and m = 0.001 MU (c), where MU is the mass of Uranus (Bou´e & Laskar 2006).
A collisionless scenario for Uranus tilting
For this calculation, the semi-ma jor axis and the eccentricity of Uranus are set to the current values, and the satellite is assumed to have a circular orbit.
