The IAU resolves that planets and other bodies in our solar system, except satellites, be defined into three distinct categories in the following way:
A planet is a celestial body that:
- is in orbit around the Sun
- has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape
- has cleared the neighbourhood around its orbit
A "dwarf planet" is a celestial body that:
- is in orbit around the Sun
- has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape
- has not cleared the neighbourhood around its orbit, and (d) is not a satellite.
All other objects except satellites orbiting the Sun shall be referred to collectively as Small Solar System Bodies.
The outer planets (Jupiter, Saturn, Uranus, and Neptune) are larger, gas giants that are predominantly composed of hydrogen and helium. They have multiple moons and ring systems and are located beyond the asteroid belt in our solar system. These planets have thick atmospheres and strong magnetic fields.
Well first of all, there are classical planets, such as the ones in our solar system, and there are dwarf planets, such as Pluto.
Classical planets
1) Has cleared its neighborhood
2) In orbit around the sun
3) Has sufficient mass
Dwarf planets
1) Has not cleared its neighborhood
2) small or undersized
3) Has sufficient mass (as do all planets)
To be a planet, a body must, essentially, orbit the star in its system. It must be big enough to be round. And, it must have cleared out the space around it.
Ceres and Pluto both orbit the sun and are round. However, they are one of thousands of bodies like them, so they are not planets.
The answer is all about sience. if you know science you know all about he planets. figure it out yourself.
The outer planets are primarily gaseous meaning they are basically just gargantuan masses of gas.
planets do not shine with their own energy but shine because of energy of stars.
they revolve around stars

What characteristics do all outer planets have in common?
they al are outer planets.
What characteristic do outer planets share?
The outer planets are primarily gaseous meaning they are basically just gargantuan masses of gas.
What is another name for the outer planets which describes their physical characteristics?
These four planets are known as the 'Gas Giant' planets.
What characteristics do all outer planets share?
All outer planets are gas giants, composed mostly of hydrogen and helium. They have no solid surfaces and are much larger than the inner planets. They are located beyond the asteroid belt in our solar system.
What are 3 special characteristics of the three outer planets?
Jupiter is the largest planet in our solar system and has a system of rings surrounding it. Saturn is known for its prominent and extensive ring system made of ice and rock particles. Uranus rotates on its side, causing it to have extreme seasons and unique magnetic field properties.
What chracteristics do to the inner planets sharewhat characteristics do the outter planets share?
I do no know what the inner planets share but the outer planets except Pluto are gas giants. inner our "rocky" ^_^
What are 4 characteristics that all of the outer planets share?
all outer planets aremade of gashave a thick atmospherethey have ringsand they are huge
What characteristics do all outer planets have in common?
they al are outer planets.
WHAT CHARACTERISTICS DO ALL PLANETS HAVE IN COMMON?
they al are outer planets.
What characteristics do all the planets share?
figure it out
What are characteristics of outer planets?
They are all gas giants.
What characteristic do outer planets share?
The outer planets are primarily gaseous meaning they are basically just gargantuan masses of gas.
Why are the outer planets classified together?
Their characteristics are similar.
What is the characteristics of the outer planets?
All outer planets have a gaseous atmosphere and are larger than planets the inner planets it also takes them longer to rotate the sun they are typically colder and have more moons.
What are the general characteristics of the 4 outer and 4 inner planets?
The 4 inner planets (Mercury, Venus, Earth, and Mars) are solid planets made of rock. The 4 outer planets are gas giants.
What is another name for the outer planets which describes their physical characteristics?
These four planets are known as the 'Gas Giant' planets.
Why do you compare outer planets to inner planets?
Outer planets and inner planets are compared because they have distinct differences in size, composition, and characteristics. Inner planets are smaller, rocky, and denser, while outer planets are larger, gaseous, and have thick atmospheres. Studying these differences helps scientists understand how planets form and evolve in our solar system.
