The 19 moons which can be regarded for being significant plenty of to are already rounded by their own individual gravity are mentioned in bold. The 7 largest moons, which are larger sized than any of your recognized dwarf planets, are stated in Daring and italic.
Triton―the biggest of Neptune’s moons―is the only real significant moon in our photo voltaic technique to orbit in the opposite route of its Earth’s rotation. It may be a captured Kuiper Belt Item.

Ganymede is crafted from rock which has a thick outer layer of ice, but compared with Europa it doesn’t exhibit indications of a freshly resurfaced surface area. Despite this, precisely the same gravitational squeezing really should be happening to some extent on Ganymede, which ought to heat up read more its interior.
Like its moon twin Namaka, Hi’iaka spins across the dwarf planet, Haumea, which seems to be an entire whole lot like an ostrich egg and spins quicker than almost some other human body from the photo voltaic system.
These are typically just some of our favorite moons, but there are numerous far more to take a look at. Plus, new moons are being identified constantly.
Europa would be the photo voltaic method’s smoothest object, suggesting its area is remade by inside procedures much more usually than most other worlds Other than Earth.
Io is definitely the closest huge moon of Jupiter and was named for just a priestess of Hera who became one of the enthusiasts of Zeus. Io has by far the most volcanic activity of any moon within the solar procedure, and its whole surface area is roofed with lava each number of thousand decades.
