How many moons does each planet have? Jupiter, Saturn, Venus


There is no secret that the Earth has only one natural satellite (our Moon), which is thought to have formed about 4.51 billion years ago, but how many moons are there in our Solar System? Some planets don’t have any other moon in the Solar System, but some planets have approximately more than 53 moons, such as Jupiter.

  • Let’s start from Mercury and Venus, so how many moons do the smallest (Mercury) and brightest (Venus) planets have?

It turns out that these two planets don’t have any other moons. The reason is:

Mercury is so near the Sun and its gravitational field that it cannot retain its moon. Each moon would hit Mercury or orbit the Sun and get pulled into the Sun. So, this is the reason why Mercury doesn’t have a moon. And what about Venus? Unfortunately, this question remains a mystery for scientists and astronomers to be solving for a long time.

  • The next is Earth, our Home Planet.

As we have mentioned above, the Earth has only one Moon. The Moon seems to be about the same size as the Sun in the sky (because it is 400x farther and larger). Therefore, the Moon covers the Sun nearly during a total solar eclipse.

  • How many moons have the Red Planet (Mars)?

The Red Planet has two moons. These are Phobos and Deimos. Phobos is slightly bigger than Deimos and circles the Martian surface at a distance of only 3,700 miles (6,000 kilometers). Like Earth’s Moon, Phobos and Deimos always present the same face to their planet. Both are lumpy and deeply cratered, with dust and loose rocks covering them. They are among the darker objects in the solar system.

  • The next is the largest planet; Jupiter. Let’s see how many moons are there on Jupiter.

The giant planet has a lot of moons, approximately 53 moons. The most well-known moons are Galilean, such as Io (pronounced eye-oh), Europa, Callisto, and Ganymede. The last one is Jupiter’s biggest moon, and not just Jupiter’s largest moon; it is also our Solar System’s largest moon. These moons are so big that you can see them with a pair of binoculars.

  • Saturn is the second-largest planet in our Solar System.

The moons of Saturn are numerous and diverse. The icy planet has 53 moons. Saturn’s moons have extensive names like Mimas, Enceladus, and Tethys. Titan is Saturn’s biggest moon, and it even has its own atmosphere, which is relatively uncommon for a moon.

  • Uranus and Neptune; how many moons do these two planets have?

Uranus has 27 moons, and half of them are made of ice. The moons of Uranus are named after characters from the works of William Shakespeare and Alexander Pope. And finally, Neptune has 13 moons. The largest one is Triton, as big as the dwarf planet Pluto.

In addition, there are 25 “unconfirmed” moons, which we’d like to bring to your attention. For example, Jupiter has 16 awaiting confirmation, Saturn has eight, and Neptune has one. And according to NASA, the moons are unconfirmed because they are waiting to get more information about them. The planet Jupiter will be home to 69 moons if all of these moons are confirmed.
