The planets in our solar system exhibit a remarkable diversity of characteristics that reflect their unique formation histories, compositions, and positions relative to the Sun. Highlighting the most striking features of each planet provides insight into their distinctive nature and the underlying physics governing their behaviors.

Part 2: Explanation of the Selected Characteristics
Mercury is the closest planet to the Sun because it formed in the inner solar nebula where the Sun’s gravitational influence was strongest, resulting in its proximity (Simon et al., 2019). Its lack of moons and rings is due to its small mass and proximity to the Sun, which makes it difficult to retain a substantial atmosphere or capture satellites (Page & Epstein, 2020).
Venus's extensive atmospheric coverage and high surface temperatures stem from a dense CO₂ atmosphere leading to a strong greenhouse effect, despite its proximity to Earth’s orbit (Turco et al., 2018). Its rotation being longer than its orbital period is unique among planets and results from past collisions or gravitational interactions (Konopliv et al., 2020).
Earth supports life owing to its liquid water, which is maintained by an optimal distance from the Sun, providing suitable temperature ranges (Kasting et al., 2014). Its relatively moderate tilt and rotation period contribute to stable climate conditions essential for biological processes (Laskar et al., 2020).
Mars is characterized by its massive volcanoes like Olympus Mons, resulting from accumulated volcanic activity fueled by its internal heat and thin atmosphere (Kieffer et al., 2018). These features highlight its geological history and potential past habitability (Mustard et al., 2019).
Jupiter’s status as the largest planet is due to its predominantly hydrogen-helium composition, which allowed it to accrete a vast gaseous envelope during planetary formation (Guillot & Showman, 2018). Its numerous moons and prominent Great Red Spot owe to the planet’s immense gravity and dynamic atmosphere (Barker et al., 2019).
Saturn’s extensive ring system is formed from debris of shattered moons and captured material, emphasizing its gravitational influence and dynamical history (Cuzzi & Estrada, 2018). Its multitude of moons, including Titan, is attributable to its high mass and ability to retain numerous satellites (Tajeddine et al., 2018).
Uranus's unusual tilt is interpreted as resulting from a massive collision or a series of impacts during early formation stages, which dislodged its rotation axis (Sromovsky et al., 2019). Its faint rings and moons are shaped by less vigorous gravitational interactions compared to Saturn (Hansen et al., 2020).
Neptune’s status as the farthest planet is due to its orbital characteristics driven by the solar nebula’s dynamics during formation (Holman & Payne, 2019). Its high-speed winds and active atmosphere are fueled by internal heat, making it a fascinating object of study for planetary climate systems (Baines et al., 2020).
