For a short answer: The giant planets have more moons than the terrestrial planets
because of their great masses which result in stronger gravitational fields
. And giant planets also occupy greater space and hold larger volumes of mass in their surrounding atmospheres.

Do outer planets have fewer moons than inner planets?
According to wikipedia, there are 173 natural satellites in the solar system. The inner planets only have 3 (Mercury and Venus have zero, Earth has one, and Mars has two). The short answer is because they’re small.
Why do some planets not have moons?
So, why don’t moons have their own moons? The answer is that
the planet they are orbiting has a much stronger gravitational pull
, so over time it would selfishly take other objects in as another moon for itself.
Which planet has fewer moons than Mars?
| Planet / Dwarf Planet Confirmed Moons Provisional Moons | Mars 2 0 | Jupiter 53 26 | Saturn 53 29 | Uranus 27 0 |
|---|
Do we have 2 moons?
Earth’s moon may not be alone. … After more than half a century of speculation and controversy, Hungarian astronomers and physicists say they have finally confirmed the existence of two Earth-orbiting “moons” entirely made of dust.
Does Jupiter have 79 moons?
Jupiter has 53 named moons and another 26 awaiting official names. Combined, scientists now think Jupiter has
79 moons
.
Does Earth have 3 moons?
After more than half a century of speculation, it has now been confirmed that Earth has two dust ‘moons’ orbiting it which are nine times wider than our planet. Scientists discovered two extra moons of Earth apart from the one we have known for so long.
Earth doesn’t have just one moon, it has three.
Can moons have moons?
So far at least,
no submoons have been found orbiting any of the moons considered
most likely to support them – Jupiter’s moon Callisto, Saturn’s moons Titan and Iapetus and Earth’s own moon.
Are there 8 or 9 planets?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then
the possible Planet Nine
. If you insist on including Pluto, it would come after Neptune on the list.
What is the hottest planet?
Planetary surface temperatures tend to get colder the farther a planet is from the Sun.
Venus
is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet.
Which planet of the inner planets is the hottest which is the coldest?
The hottest planet in the solar system is
Venus
with an average temperature of 464 degree Celsius and the coldest planet in the solar system is Pluto with an average temperature of -225 degree Celsius.
Did Venus have a moon?
One of biggest mysteries in the solar system is why
Venus has no moon
. A new model suggests that our sister planet may have in fact had a moon, but that it was destroyed. Earth’s moon is thought to have formed when a Mars-size body struck the early Earth, hurling material into orbit, where it coalesced.
Which planet rotates the fastest?
Jupiter
is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.
Why is Venus the hottest planet?
Although Venus is not the planet closest to the sun,
its dense atmosphere traps heat in a runaway version of the greenhouse effect
that warms Earth. As a result, temperatures on Venus reach 880 degrees Fahrenheit (471 degrees Celsius), which is more than hot enough to melt lead.
Is moon a star?
An example of a star is the sun which the earth revolves around in orbit. … The moon, on the other hand, is solid and very small in size and does not have anything orbiting around it. Therefore
the moon cannot be classified as a star.
