Francisco, Moon of Uranus

Francisco is a Moon that orbits round the planet Uranus. It is also know by other designations, XXII, S/2001 U3. Its mass is estimated/calculated at being 8,392,543,225,344,280 kg. Its density has been calculated at being 1.5. Its volume is 5575.

Francisco was discovered on 13 August 2001 by John J. Kavalaars, Matthew J. Holman, Dan Milisavljevic, and Tommy Grav..

The orbital period, i.e. the period it takes to complete an orbit round Uranus is 266.6 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 11km. The Equatorial Radius is based on the assumption of the Albedo value. The value is the radius in km of the said object at the Equator.

The albedo of the object is 0.04. The Albedo is the amount of radiation that is reflected back into space by the object.

The Escape Velocity of the object is 36 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 4276, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Francisco is 69.1 km. The surface area of Francisco is 1,520.53. The surface gravity of the said item is 0.005. The Mean orbit velocity, that is the speed at which it orbits is 4179.60 km/h. The is the average distance in km of the object is from its parent 4282900.00.

The orbital inclination, the angle at which Francisco orbits in relation to the orbital plane is 147.25 degrees. The orbital eccentricity is 0.1324, it is the degree at which Francisco orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
