Mars is so small because Jupiter shook up its formation



In the article, “Mars is so small because Jupiter shook up its formation,” the author talks about Jupiter and how the formation of itself affected other planets like mars from forming to be as big as it was suppose to. For example , “Models of our solar system’s formation suggest that Mars should be between 1.5 and two times Earth’s mass. Instead, it weighs in at a mere one-tenth the mass of our world.” The author talks about scientifically Jupiter was formed. The author states “The disc’s gravity pulled the protoplanets’ axes of rotation in one direction, but the gravity from Jupiter came from the opposite direction, tugging them that way. When those competing forces balanced in a certain way, 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.” However than a new team disapproved the old theory and is going to publish a paper with some changes . The author states the exact change saying “Recent studies of meteorites suggest Mars formed much more rapidly than [Lin’s team] assumed, so we worked out the consequences for a disc that evolves more rapidly,”

The Objective was to be able to describe the nature of our solar system and how it was formed and this article relates. It relates because it discusses the formation of Jupiter and Mars. In our lecture tutorial,“Temperature and Formation of Our Solar System,” we learned that the planets divide clearly into two groups. Jupiter is a jovian planet, along with Saturn, Uranus, and Neptune. Jovian planets are giant gaseous planets similar in overall composition to Jupiter. Mars is a terrestrial planet, along with Mercury, Venus, and Earth. Terrestrial planets are rocky planets similar in overall composition to Earth. According to the tutorial, jovian planets form at temperatures cooler than the freezing point of water and at a distance of 3AU and higher from the Sun. Terrestrial planets form at temperatures hotter than the boiling point of water and at a distance of 0 to 2AU from the Sun. This article also makes reference to a protoplanetary disc surrounding the Sun. We learned in class that it is believed that the solar system formed from the gravitational collapse of a great cloud of gas and dust. Our solar system began with a disk of material surrounding a young star and all the leftover material can form planets. The fact that our solar system began as a spinning disk of gas and dust explains the orderly motions we observe today.

I found this article interesting and very suitable for this objective because i felt like it covered mostly everything we covered in class. Furthermore , what made me like it more than just similarities ion class is i never actually thought the gravity of one planet could actually affect another. Therefore, i enjoyed this article because it explained to me how this was actually possible.
