a solar system model wont show what the actual size solar system can be hiding
It is Neptune, now.
Yes. Neptune is the outermost planet in the solar system.
Try some of the links - one should suit your needs. To include the full rotation of the planets in real time, is not an easy, nor cheap, option. It would require precise mechanical movements.
it was proposed by edward Édouard Roche it's not so real .... no supporting evidence is there for this hypothesis
Most likely due to the scales used. To show the whole solar system on a page of a book or a small 3d model you have to show the planets as being larger than they actually are, with shorter distances between them. To build a scale model of the solar system you would need a large playing field to appreciate the distances and relative sizes of the planets, which themselves would be represented by ping pong balls, ball bearings etc. spread several metres apart.
The sun, followed by the gas giant planets.
At the time, the Solar System was believed to be fake. People believed only Earth was real.
then who do u think made the solar system
It is Neptune, now.
answer
Because we can't yet actually go there. A mathematical model or computer simulation is a poor substitute for the real thing, but for now, it will have to do. We send robot probes to Mars, to Titan, to orbit Jupiter and Saturn and Venus, and we create simulations of what things might be like there. It's better than nothing....
With the saucer Excalibur, you go to the Pewter Moon, and there you make a real spaceship to travel the solar system. (see related question)
The model is similar to the real object because of how it is three-dimensional.
Creating an abstract system of equations which describes (and helps reasoning about) a real life system.
A model that imitates something in the real world is called a simulator. A simulation imitates the operation of a real world or system over time.
a model can not replicate all real world conditions --- study island :)
