Planets and their Moons list
Moons of Mercury: 0
Moons of Venus: 0
Earth’s Moon: 1
Moons of Jupiter: 80
Moons of Saturn: 83
Moons of Uranus: 27
Moons of Neptune: 14
here is the table given for IAU recognized 5 Dwarf Planets and their moons list:
| 5 Dwarf Planets | Number of Moons |
| Ceres | 0 |
| Pluto | 5 |
| Haumea | 2 |
| Makemake | 1 |
| Eris | 1 |
Now here is the table for some Possible Dwarf Planets (most-likely dwarf planets) and their number of moons list:
| Possible Dwarf Planets | Number of Moons |
| Orcus | 1 |
| Salacia | 1 |
| Quaoar | 1 |
| Gonggong | 1 |
| Sedna | 0 |
So here you saw only Ceres and Sedna do not have any moon. These listed Dwarf Planets and Possible Dwarf Planets are in order of increasing distance from the Sun. Hence the interesting facts are, Ceres is the nearest and Sedna is the farthest on this list.
Thus the total number of moons of Dwarf Planets and Possible Dwarf Planets are:- (5+2+1+1)+(1+1+1+1)= 13
Minor Planet Moons list
The minor planet moons are small astronomical objects that orbit the minor planet. These moons are also known as ‘companions or satellites’.
There are millions of minor planets in our solar system. Minor planets are asteroids, dwarf planets, and other small solar system bodies. According to scientists, there may be thousands of minor planets that may have at least one moon.
By 2023 so far, there are almost 457 known minor planets that may have a total of 477 moons. In these 477 moons, some moons of binary asteroids and some moons of triple asteroids have been also added.
Ida was the first discovered asteroid that has a moon. Its moon name is Dactyl and it was discovered by Galileo spacecraft in 1993 when it flyby Ida.
Here a list of few asteroids is given with their moons names and size in diameter:
| Asteroids | Moons Names with Diameter |
| Ida (243 Ida) | Dactyl (Ida 1), 1.4 km |
| Sylvia | Romulus, 10.8 km |
| Remus, 10.6 km | |
| Eugenia | Petit-Prince, 7 km |
| S/2004 (45) 1, 5 km | |
| Kalliope | Linus, 28 km |
| Antiope | S/2000 (90) 1, 88 km |
| Hermione | S/2002 (121) 1, 32 km |
| Emma | S/2003 (283) 1, 9 km |
So these were few main asteroids and their moon names list with diameter. As mentioned few asteroids have multiple moons.
Conclusion for how many moons in the solar system?
Adding the moons is not a tough task, but scientists are continuously searching. So the list is continuously increasing.
So let me add all the moons of the solar system:
Moons of Planets + Moons of Minor Planets = 207 + 477 = 684
