|
All of the planets move too fast to study.
|
|
|
Since planets orbit on the different planes they can’t all be seen at once.
|
|
|
All objects in space are moving relative to one another.

|
|
Movement within our solar system is unpredictable.

Detailed explanation-1: -The enormous ratio of interplanetary distances to planetary diameters makes constructing a scale model of the Solar System a challenging task. As one example of the difficulty, the distance between the Earth and the Sun is almost 12, 000 times the diameter of the Earth.
Detailed explanation-2: -It’s not just the distances between planets that are large. There are also huge differences in the size of each planet. Because of this, it can be difficult or even impossible to display both planet size and distance accurately, especially in smaller scale models like an image.
Detailed explanation-3: -It says a planet must do three things: It must orbit a star (in our cosmic neighborhood, the Sun). It must be big enough to have enough gravity to force it into a spherical shape. It must be big enough that its gravity cleared away any other objects of a similar size near its orbit around the Sun.
