Uranus Moons: Names, Numbers, and List in 2020

uranus moons

Planet Uranus has a total number of 27 moons till 2020. In the total number of Uranus moons, 5 are the major moons, 13 are the inner moons, and rest 9 are the irregular moons. 

The inner moons of planet Uranus exist in the region of its ring and are small in size. Whereas the major moons are the comparatively larger Uranus satellites. ‘Titania’ comes in the category of major Uranus moons and is the largest moon of Uranus. 

Here in this article, we have mentioned some important information about the Moons of Uranus. Such as the number of moons, names, moons list with some facts and information. 

Uranus Satellite – Facts and Information

British astronomer ‘Frederick William Herschel‘ discovered the planet Uranus in March 1781 with the help of his own made telescope. Six years later he discovered two major and largest Uranus moons ‘Titania’ and ‘Oberon’ in January 1787. 

English astronomer ‘William Lassell‘ discovered the other two major Uranian moons ‘Ariel’ and ‘Umbriel’ in 1851. Whereas in 1948, a Dutch astronomer and planetary scientist Gerard Kuiper discovered the smallest major uranian satellite ‘Miranda’. 

Most of the Uranus moons discovered by space probe Voyager 2, when it flew near to Uranus in 1985. And remaining natural satellites of Uranus discovered with the help of the advanced telescopes from the earth. 

Titania is the largest moon of Uranus with a diameter of around 1578 km (981 miles). It is the eighth-largest natural satellite in our solar system. 

Titania has many huge impact craters, some are around 300 km in diameter. But the second-largest moon of Uranus ‘Oberon’ has some larger craters than Titania. 

The irregular moons of the Uranus exist at larger distances and mostly have retrograde orbits. Whereas the inner moons of Uranus share their orbit with its ring system. 

Uranian satellites have some special facts while considering their names. In our solar system planets, most of the names of the planet’s satellites are taken or related to mythologies, but here the fact is different. The names of the Uranus moons are mostly taken from the characters in the works of William Shakespeare and Alexander Pope

The major moon ‘Miranda’ has a totally icy surface, whereas other major uranian moons (Ariel, Umbriel, Titania, and Oberon) are made of rock and ice. 

The nearest moon of the Uranus is Cordelia with an average distance of around 50,000 kilometers, whereas the farthest moon to Uranus is Ferdinand with an average distance of around 20.40 million kilometers. 

Uranus Moons – Number, Names, and List

Here you can find Uranus number of moons with a proper list of names. These mentioned names of Uranian moons are in order of increasing distance from the Uranus.  

Order:- “Moon name- distance from Uranus (in million km)- moon diameter (in km)”

  1. Cordelia– distance: 0.049 million km- diameter: 45 km
  2. Ophelia– distance: 0.053 million km- diameter: 48 km
  3. Bianca– distance: 0.059 million km- diameter: 55 km
  4. Cressida– distance: 0.062 million km- diameter: 84 km
  5. Desdemona– distance: 0.063 million km- diameter: 70 km
  6. Juliet– distance: 0.064 million km- diameter: 100 km
  7. Portia– distance: 0.066 million km- diameter: 142 km
  8. Rosalind– distance: 0.069 million km- diameter: 80 km
  9. Cupid– distance: 0.074 million km- diameter: 18 km
  10. Belinda– distance: 0.075 million km- diameter: 105 km
  11. Perdita– distance: 0.076 million km- diameter: 35 km
  12. Puck– distance: 0.086 million km- diameter: 165 km
  13. Mab– distance: 0.097 million km- diameter: 25 km
  14. Miranda– distance: 0.13 million km- diameter: 472 km
  15. Ariel– distance: 0.19 million km- diameter: 1158 km
  16. Umbriel– distance: 0.26 million km- diameter: 1175 km
  17. Titania– distance: 0.43 million km- diameter: 1578 km
  18. Oberon– distance: 0.58 million km- diameter: 1525 km
  19. Francisco– distance: 4.27 million km- diameter: 22 km
  20. Caliban– distance: 7.16 million km- diameter: 50 km
  21. Stephano– distance: 7.95 million km- diameter: 32 km
  22. Trinculo– distance: 8.50 million km- diameter: 18 km
  23. Sycorax– distance: 12.20 million km- diameter: 170 km
  24. Margaret– distance: 14.42 million km- diameter: 20 km
  25. Prospero– distance: 16.20 million km- diameter: 50 km
  26. Setebos– distance: 17.54 million km- diameter: 48 km
  27. Ferdinand– distance: 20.45 million km- diameter: 20 km

So these were all 27 Uranus moons listed. There have been only 27 are detected till 2020. Planet Uranus is much farther to us, so it becomes difficult to detect small bodies near to it. Therefore scientists believe there could be many smaller Uranus satellites. Hope the list of Uranus moons will increase soon.
