Why have the Jovian planets retained their atmospheres?
Simply because the gas giants are so big that the force of gravity is sufficient to retain the light gases.
What are the small planets and big planets?
the smallest is Pluto and the biggest is Jupiter
Do Jovian planets have moons?
Yes a Jovian type planet in another star system can have a moon as big as Mars. As of June 2014, it is unknown if one exists.
How big is earths moons compared to other planets?
Small
Why are terrestrial planets rocky?
nobody really knows. some people think it was the big bang, others think god did it. but i think 2 or more meteors colliding form rocky and rough planets.
How are inner planets differ from outer?
The Jovian planets (Jupiter, Saturn, Uranus and Neptune) are composed of gases and pressurized liquids. Whereas, the four terrestrial planets (Mercury, Venus, Earth and Mars) are composed of rock and iron.
Which is not a Jovian planet?
Pluto is the only "planet" that isn't a planet. Well I think that the IAU still have not answered the question WHAT MAKES A PLANET A PLANET? Is it a certain size or something? Comment : The IAU have defined a planet. The definition is mainly about size, but it's not simple: 1) The object must be big enough for gravity to have formed it into a (roughly) spherical shape. 2) The object must be by far the largest object in the neighbourhood of its orbit. Pluto qualifies on 1) but fails on 2). Also, Venus and Mercury are sometimes called "morning stars" or "evening stars", but they are planets.
Why are the outer planets call the gas giants?
The outer planets (with the exception of the dwarf planet - Pluto) are called "gas giants" for two reasons - they are GIANT (in size/mass/gravity etc.) compared to Earth and the inner solar system "rocky" or "terrestrial" planets and are composed mainly of a gaseous atmosphere (with, its hypothesized, a small rocky core at the center).
Why is Pluto not a jovian planet?
It's not even a planet, but a dwarf planet. Jovian Planets are big and not solid.Pluto is a solid object with a relatively thin atmosphere.Pluto is small, smaller than any true planet in the solar system.Pluto is not a planet but a dwarf planet.
What are the 7 big crustal planets?
Solid or terrestrial planets are those whose primary mass is land. The terrestrial planets in the Earth's solar system include Earth, Mercury, Venus, and Mars.
Why have the Jovian planets retained their atmospheres?
Simply because the gas giants are so big that the force of gravity is sufficient to retain the light gases.
Are dwarf planets small?
They are small compared to other planets but big compared to us.
What are the small planets and big planets?
the smallest is Pluto and the biggest is Jupiter
Is Earth a big ball of gas?
No. It is a terrestrial planet like the other inner planets, meaning it is mostly rocky.
How many years does it take for all the planets to align?
The time it takes to get from one planet to another depends on the departure and arrival planets. It can take about two years to get from Earth to Mars where it will take about six years to get from Earth to Jupiter.
Are the inner planets small or big?
Small, considering the rest of the planets. But in actuality they are large. As said before, in accordance with the rest of the planets in our Solar system, yes they are small.
Explain how the inner planets are different from the outer planets?
Inner planets small and rocky. Outer planets big and gassy.
