The formation of the solar system is a complex process that began approximately 4.6 billion years ago with the gravitational collapse of a giant molecular cloud. This turbulent nebula accumulated dust and gas, gradually contracting under gravity to form a rotating protoplanetary disk. Within this disk, particles collided and coalesced to create planetesimals, which further amalgamated into the planets, moons, asteroids, and comets we observe today. The Sun formed at the center of this nebula, igniting nuclear fusion and becoming the star around which all other solar system objects orbit (Chaisson & McMillan, 2014).

To visualize Earth's internal structure, a cross-section diagram can illustrate different layers: the crust, mantle, outer core, and inner core. The Earth's crust comprises solid rock and soil, hosting various landforms and ecosystems. Beneath the crust, the mantle consists of semi-solid silicate rocks that convect slowly, driving plate tectonics. The outer core, made of liquid iron and nickel, generates Earth's magnetic field through dynamo action, whereas the inner core, composed of solid iron-nickel alloy, remains extremely hot, with temperatures reaching up to 5,700°C (Stewart, 2012). The atmosphere surrounding Earth is predominantly nitrogen (78%) and oxygen (21%), with trace amounts of other gases. This atmosphere sustains life by providing essential gases, protecting from solar radiation, and contributing to weather and climate systems (Kahre et al., 2018).

The other terrestrial planets—Mercury, Venus, and Mars—possess solid, rocky surfaces similar to Earth but differ significantly in atmospheric composition and geology. Mercury has a heavily cratered, rocky surface with almost no atmosphere, resulting in extreme temperature fluctuations. Venus features a dense, thick atmosphere dominated by carbon dioxide, creating a potent greenhouse effect and surface temperatures hot enough to melt lead. Its surface is volcanic and tectonically inactive, covered by extensive volcanic plains and highland regions (Esposito, 2020). Mars exhibits a thin, mostly carbon dioxide atmosphere with surface features that include dry riverbeds, polar ice caps, and massive volcanoes like Olympus Mons, indicating a history of volcanic activity and water erosion (Carr & Head, 2010). These planets reveal diverse geological histories influenced by their atmospheres and internal processes.

Beyond the terrestrial planets, the solar system hosts various objects such as asteroids and comets. Asteroids are rocky remnants primarily located in the asteroid belt between Mars and Jupiter. They vary in size and shape, often showing cratered surfaces scarred from collisions. Comets are icy bodies originating from the Kuiper Belt and Oort Cloud; they develop visible tails when approaching the Sun due to sublimation of their ices, displaying spectacular halos and tails as they orbit (Hughes, 2011). Additionally, dwarf planets like Pluto inhabit the Kuiper Belt, characterized by icy, geologically active surfaces and complex atmospheres, further enriching the diversity of objects in our solar system.

Focusing on specific celestial bodies, Earth remains the only planet known to support life, with a dynamic surface, active geology, and a breathable atmosphere. Contrasting Earth with Mars, the latter lacks substantial atmosphere and surface water, making it inhospitable. A minor planet or dwarf planet such as Pluto provides a glimpse into icy, distant worlds with geological activity and thin atmospheres, yet less hospitable than Earth (Stern et al., 2015). An exoplanet, such as Proxima Centauri b, located outside our solar system and orbiting a red dwarf star, presents new possibilities for habitability and planetary diversity. Compared to Earth, exoplanets can vary in size, composition, and atmosphere, expanding our understanding of planetary systems (Anglada-Escudé et al., 2016).
