Puck, Moon of Uranus

Puck is a Moon that orbits round the planet Uranus. It is also know by other designations, UXV, S/1985 U1. Its mass is estimated/calculated at being 2,893,928,744,310,680,000 kg. Its density has been calculated at being 1.3. Its volume is 2226095.

It was discovered in the year 1986 by S. Synnott, Voyager 2.

The orbital period, i.e. the period it takes to complete an orbit round Uranus is 0.76183 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..

The Equatorial Radius of the object is 81km. The value is the radius in km of the said object at the Equator.

The Escape Velocity of the object is 249 km/h. The Escape Velocity is the speed an object needs to be travelling in order to break free from the objects gravity. The larger an object is, the more velocity (speed) is needed to break free from the object.The Semi-Major Axis of the orbit is 86, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Puck is 508.9 km. The surface area of Puck is 82,447.96. The surface gravity of the said item is 0.029. The Mean orbit velocity, that is the speed at which it orbits is 29546.90 km/h. The is the average distance in km of the object is from its parent 86000.00.

The orbital inclination, the angle at which Puck orbits in relation to the orbital plane is 0.32 degrees. The orbital eccentricity is 0.0001, it is the degree at which Puck orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Puck is a small moon that orbits Uranus. It was only discovered when Voyager 2 space probe visited the planet in 1986. All that we know of the moon has come from that encounter. Puck orbits just outside the rings of Uranus and before the first of the Uranus's major moons, Miranda. It was the only newly discovered moons of Uranus to be discovered in enough time to be examined. The pictures of Puck are not very clear or detailed.

Puck Mythological Legend

Like so many other moons of Uranus, there is no ancient legend behind the naming of this moon. Like most of the other moons of Uranus, this was named after a character from the William Shakespeare play, "A Midsummers Night Dream". Puck is a sprite, a servant of Oberon, the King of the Fairies. It was apt because both the moon and the character are both small. Uranus moons are unique, that are not named after ancient deities.
