Mars Compared to the Sun
Mars and the Sun are vastly different celestial bodies. Mars is a terrestrial planet, smaller and colder than Earth, with a thin atmosphere and diverse surface features. In contrast, the Sun is a massive, hot, luminous ball of plasma, the central body of our solar system.
Mars orbits the Sun as a planet, dependent on the Sun’s gravitational pull, but in terms of size, composition, and nature, the two are distinct entities with unique roles in our cosmic neighborhood.
Overview of Mars
Mars as a Terrestrial Planet
Mars is the fourth planet from the Sun and the second smallest planet in our solar system. It is a terrestrial planet, meaning it has a solid surface made up of minerals and rocks. Learning about Mars gives insight into the formation and evolution of rocky planets like Earth.
Key characteristics
Mars has a reddish, rusty appearance due to iron oxide on its surface. It has two small moons called Phobos and Deimos. Mars’ atmosphere is very thin compared to Earth’s. This means it cannot retain heat very well, resulting in colder surface temperatures.
Mars’ axial tilt and rotation period also give the planet seasons and days similar in length to those on Earth. The red planet’s characteristics, like potential evidence of ancient water flows, have driven much scientific interest regarding habitability. So, since Mars has similarities with our Earth, it’s only natural for scientists to believe in Mars as a promising place to search for life beyond Earth.
Mars’ composition and structure
Mars has a dense metallic core composed of iron, nickel, and sulfur. Surrounding the core is a rocky mantle and crust made up of elements like silicon, oxygen, and magnesium. The crust averages about 50 kilometers thick. Understanding Mars’ internal structure provides clues to how terrestrial planets form.
