The and the are attracted to each other. The sun is much larger than the planets and can influence the of the planets.

Yes, the patterns in the movements of the planets might be related to what happened in the system. A model with relative sizes and distaqnces allow us to See all of the at once. There is one group of planets that are smaller and denser( , , and . The other group of planets are larger but much less dense. The planets would most likely appear to be more spread out in the , instead of close together in a line.

Over a period of or could gather data about the relative positions of Earth, a and the sun. Analysis of the observations could be used to determine how planets move in relation to the Earth and the sun. It would not be possible to draw the solar system to scale in this space and to be able to still see the planets and they relate to each other. The distance from the planet to the sun would follow the pattern seen in the table. A little less than twice the distance from Mars to the sun is where the belt is located. The distance would most likely be between 2.6 and 3.0 Aus. Scientists form hypothesis based on observations they can make and their knowledge of physical processes that may be the same on Earth and in the entire . By making predictions, comparing observations, and gathering data scientists can develop theories about distant phenomena. 1. Swirling gas and 2. Small particles clump

3. Larger particles attract 4. The large form the more sun and the planets The third criterion of Kant’s describes how nebular dust gathers into clumps. As the clumps become larger, they attract additional particles, clearing the space around them. Just as “planets clear the neighborhood because their mass attracts smaller bodies as they .

The would move off into space if the gravitational pull between Earth and satellites no longer existed. • Earth’s will affect the path of the when it takes off. • If the probe does not reach a high enough , it may fall back to Earth. • When the probe gets closer to it will be affected by Jupiter’s gravity. • It will need to approach Jupiter at exactly the right angle so that it enters an orbit. If the angle is incorrect the probe will crash into Jupiter.
