The article that I recently read was titled, “Mars is so small because Jupiter shook up its formation“. This specific article directly ties into our tenth conceptual objective, “I can describe the nature of our solar system and how it was formed”. This article begins by a very blunt way of what astronomers believe is the reason for Mars’ size. Abigaill Beall simply states, “Mars can blame Jupiter for its small stature. The Red Planet may be much smaller than we expect because Jupiter’s gravity beat it up as it was forming”. Many experts say that Mars’ mass is supposed to be 1.5 and 2X Earth’s mass. Instead, it weighs in at a shy one-tenth mass of our world. A theory that was once said is suddenly resurfacing. Some say that after the formation of Jupiter, gas that was left over meddled with the rocks that ultimately built Mars. Therefore, instead of them clumping together, they seemed to fall apart. The gas giants formed by accreting gas from the protoplanetary disc that surrounded the sun. As they increased in size, their gravity started to have more impact than the remaining disc on the still-forming rocky planets. I think this was a great article to correlate with our objective. When the gravitational pull collided between the two, the protoplanets felt a kick from Jupiter’s Gravity at the same point in their orbit around the sun, an effect known as sweeping resonance. In our lecture, we discussed that scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust. Many meteorites even discovered that Mars grew much more rapidly than assumed. Therefore, the consequences for a disk that resolves more rapidly was discussed
I felt like this article was a great representation of our conceptual objective we had to elaborate on. Before discussing this topic in class and reading this article, I did not know the outside forces can alter a planet’s size forever. In addition, we learned in our lecture-tutorial handbooks that there are two type of planets.First is the Jovian planets (gas planets) which formed at temperatures cooler than the freezing point of water. Next, is the terrestrial planets (rocky planet) which formed hotter than the boiling point of water. Just by knowing that planet Earth was ultimately formed as a spinning cloud of dust, certainly blows my mind. You just think of how evolved our planet is and what it withholds, and find it crazy how just a simple natural act created it. I strongly believe this article helped me immensely understanding our tenth objective, “I can describe the nature of our solar system and how it was formed”.
