Because he is curious about it but mainly because the problem of finding out why the planets move as they do was the major factor that puzzled scientists for the best part of 2000 years. It drove them mad but it was not too difficult to be solved by the best minds by the time the 18th century came along. Names like Ptolemy, Copernicus, Tycho, Kepler, Galileo and Newton all contributed to this heroic effort. From those studies we now have modern science, which makes all our lives easier in theory . . :)

The main interior regions of the Sun are the core, where nuclear reactions generate energy, the radiation.
because it fun
Astronomers mean a replication of the Sun. This means make a smaller model or a life size mode of the Sun.
The planets of our solar system are most definitely NOT all the same size.
Over 1,000 planets the size of Earth can fit on Jupiter.
Putting the planets in order by size is:JupiterSaturnNeptuneUranusEarthVenusMarsMercury
The answer is true
Astronomers mean a replication of the Sun. This means make a smaller model or a life size mode of the Sun.
The size differences between the larger and smaller planets and the size of the sun is one problem. In order to get the scale of a model to correspond correctly to the solar system, the model would have to be fairly large. Otherwise, the smaller planets would be little more than dots. Even if the smallest planet was represented with a small marble, the sun and larger planets would need to be represented with much larger objects. This in turn would effect getting the distances correct.
Planets or dwarf planets, depending on their size. (The larger ones would be planets, smaller would be dwarf planets.)

No, they would only need 1.2 planets.
They are all bigger
Once you know their distances, you can determine basic properties of the planets such as mass, size, you can determine its linear diameter.
Both planets would be destroyed, as the gravitational pull would rip off matter from both planets, and they would be ripped apart.
Yes. . Physics is the science of modeling the universe around us, and then examining that model to better understand the characteristics and workings of our universe. Our current heliocentric model of the solar system lets us understand the orbital parameters of the planets, as well as the characteristics of the planets, such as their mass, size, density, expected temperature, and so on.
The planets are normally classified in size by their equatorial diameter.
But you CAN determine the size of the planets: in diameter, overall mass, and in density.
The average sizes of the outer planets are smallest than the average size of the Pluto so that they can called them the dwarf planets.
