I found an article on Space.com, titled, “How Did the Solar System Form?”, by Taylor Reed. This article explains how approximately 4.5 billion years ago our solar system was formed. It said that scientists have developed three different models to explain how planets in and out of the solar system may have formed. First is the core acceleration model, which explains the formation of terrestrial planets but has a problem with the Jovian. Then is the pebble accretion model, which allows planets to form fast from the smallest material. Lastly there is the disk instability method, which accounts for the creation of our giant gas planets. I found this article relating to our 10th conceptual objective because it talks about the formation of our solar system. We learned that gravity pulled on clouds of dust and gas to make our solar system. In our lecture tutorial books we learned that there are two type of planets. First is the terrestrial planets (rocky planet) which formed hotter than the boiling point of water. Then there is the Jovian planets (gas planets) which formed at temperatures cooler than the freezing point of water. The article was an interesting read because I did not know that there were different types of models that explain how of solar system was formed.
