It stands out from the Sycorax group by its inclination, which is only 56.63°, whereas all of the Sycorax group moons are retrograde, with inclinations in the 140-170° range. Generally, this would mean it is not likely dynamically connected with the Sycroax group other than by having coincidentally a similar semimajor axis. Jump to: navigation, search Sycorax is a fictional character mentioned though not seen in William Shakespeares play The Tempest. ...
