All jovian planets are massive and they do
have stronger gravitational force
. … Because the giant planets gravitationally dominate a very large area, they also more easily capture passing objects as moons. Well that’s the answer to why giant planets have more moons compared to terrestrial planets.
How does the nebular theory explain why Jovian planets are so much more massive than terrestrial planets?
The jovian planets, however, formed farther from the Sun where ices and rocks were plentiful. The
cores accreted rapidly into large clumps of ice and rock
. Eventually, they got so large, they captured a large amount of hydrogen and other gasses from the surrounding nebula with their enormous gravity.
Why did the Jovian planets end up with so many moons?

What explains why the Jovian planets have the largest number of moons?
Not only is Jupiter the largest planet in the solar system, it is also the most massive at more than 300 times the mass of Earth. Its size plays a role in the number of moons orbiting Jupiter
because there is a large area of gravitational stability around it to support many moons.
What does the nebular theory suggest?
Currently the best theory is the Nebular Theory . This states that
the solar system developed out of an interstellar cloud of dust and gas, called a nebula
. This theory best accounts for the objects we currently find in the Solar System and the distribution of these objects.
What is the biggest moon on Neptune?
Overview.
Triton
is the largest of Neptune’s 13 moons. It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet’s rotation―a retrograde orbit. Scientists think Triton is a Kuiper Belt Object captured by Neptune’s gravity millions of years ago.
What is a Jovian planet?
Also called “giant planets,” the Jovian planets
occupy orbits in the outer solar system at distances ranging from 5 (Jupiter) to 30 (Neptune) times the Earth’s distance from the Sun
. … The planets also have fierce winds and storms, and a rapid rotation. When compared to Earth, the Jovian planets are enormous.
What are the 6 stages of nebular theory?
- Nebula, protosun forming, spinning planetary disk, protoplanets forming,
- Shock waves from a nearby supernova explosion.
- It also begins to flatten.
- Protosun.
- When the gravitational forces begin to fuse hydrogen into helium (fusion)
- Protoplanets.
- Inner protoplanets – most of their lightweight gases are boiled away,
Why are there two major types of planets?
why are there two major types of planets? …
accretion built ice-rich planetesimals in the outer solar system
, and some of these icy planetesimals grew large enough for their gravity to draw in hydrogen and helium gas, building the jovian planets. what ended the era of planet formation?
What is the hottest planet?
Venus
is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
What are the 4 Galilean moons?
A comparison “portrait” of Jupiter’s four Galilean moons
Io, Europa, Gany- mede, and Callisto
, each with different characteristics.
What are the 5 largest moons of Jupiter?
ESA Science & Technology – Jupiter’s largest moons
From top to bottom, the moons are
Io, Europa, Ganymede and Callisto
.
Why does Jupiter have 79 moons?
The further you travel from the sun, the weaker its gravitational pull on you becomes. Therefore, if Namouni is correct, the real Jupiter has 79 moons and counting because it’s
an insanely massive planet that’s far enough away from the sun to avoid lunar theft
.
Why was the nebular theory rejected?
The main problem involved
angular momentum distribution between the Sun and planets
. The planets have 99% of the angular momentum, and this fact could not be explained by the nebular model. As a result, astronomers largely abandoned this theory of planet formation at the beginning of the 20th century.
Why is the nebular theory the most accepted theory?
The nebular theory holds that the solar system formed from the gravitational collapse of a great, giant cloud of gas and dust. This theory is widely accepted by scientists today because
of its success in explaining the major characteristics of our solar system
.
What are the 4 steps of the nebular hypothesis?
- step one(4) -The solar nebula consisted of. -hydrogen,
- step two(2) -A disturbance.
- step three(2) -The solar nebula assumed a flat, disk shape.
- step four(2) -Inner planets began to form from metallic.
- step five(2) -Larger outer planets began forming from fragments.
