Is a comet and a meteor considered to be small planets?
No, comets and meteors are not considered to be small planets. Comets are simply considered to be comets, and meteors are simply considered to be meteors. (Meteors are asteroids that have entered the atmosphere.)
How can Saturn's mass be greater that Earth?
Quite simply, different planets have different masses. They are not all the same.
How many planets does it take to make a solar system?
A solar system could simply have one planet, the most important thing is that it has to have a sun with celestial bodies that revolve around it in its gravitational field to be classified as a solar system.
Are earth moon sun planets if not what are they?
The Earth is a planet. OurMoon is simply "a moon". That's an object that orbits a planet. The Sun is a star.
How did Nickolaus Copernicus account for the retrograde motion of the planets?
The retrograde motion of the planets is well modelled by both the Ptolemaic system and the Copernican system, and by the other models. But the Copernican system explains it more simply because, for example, Mars's retrograde motion is caused simply when Mars is overtaken by the Earth, which goes more quickly round the Sun. Thus an observer on the Earth sees Mars appearing to go 'backwards' on the ecliptic around the time of closest approach (opposition). This can be easily demonstrated by assuming simple circular orbits.
What star does all the planets orbit around?
I think that is refered to simply as the sun, or "Sol".
What is called our groups of planets that revolves around the sun?
It is simply called "The Solar System"
What is the Trojan planets that revolve around the sun in the lagrangianpoints of Jupiter's orbit?
They are simply asteroids. Sometimes they are called "minor planets", but they are much smaller than planets, of course. The Trojans can orbit where they do because those places are suitable for stable orbits.
What is the falling action of the oval portrait?
There is no falling action the story simply ends at the Climax!
Who purposed theory all planets revolve round sun?
Copernicus made a contribution to Astronomy by proposing the theory called "Heliocentrism", which means that simply the Earth and all of the other planets revolve around the stationary Sun.
Why doesn't earth simply fall into the sum?
Gravity is caused by mass, so objects with more mass, such as planets and stars, exert a lot of gravity. The earth and everything on it is constantly falling towards the sun because of the sun's immense gravity. Because of this sideways momentum, the earth is continually falling towards the sun and missing it.
What is a hairdressing gown?
It's a (usually cloth or plastic) cape placed around the neck of the customer - to stop cut hairs from simply falling over their clothes.
Can rain reproduce?
No. Rain is simply water falling from the sky.
Is a comet and a meteor considered to be small planets?
No, comets and meteors are not considered to be small planets. Comets are simply considered to be comets, and meteors are simply considered to be meteors. (Meteors are asteroids that have entered the atmosphere.)
Which planets are often called the rocky planets and why are they called so?
Mercury, Venus, Earth and Mars are the Rocky planets. They are called so simply because they are rocky, their outer layer is solid. All other planets in the solar system are gaseous.
What forces keeps the planets in their orbits?
Gravity keeps the planets from shooting off in to space, while the planet's momentum prevents in from falling in to the sun. When these are balanced, an orbit is achieved.
How do we know that planets rotate?
Simply by looking at the planet itself. If it's spinning, then it rotates.
