In our solar system, Mercury is regarded as the innermost planet next to the Sun. Pluto is usually considered to be the farthest from the Sun, even though it was actually reclassified to be called a dwarf planet. Mercury has its extreme variations of temperature between hot daytime and icy night-time, due to being close to the Sun, coupled with having cratered surface features and lacking atmospheric cover, leading to this severity.
Pluto orbits the Sun much farther away than the other planets. Its orbit carries it far beyond the main planets, and therefore it is much colder and has a very thin atmosphere that can freeze and thaw with its position in orbit. Pluto is one of the small icy bodies located in a region called the Kuiper Belt.
The contrast between Mercury and Pluto will show the range of planetary environments in our solar system. Mercury has extreme heat with a cratered surface, which is in sharp contrast to Pluto’s icy surface and distant orbit. Together, they represent the range of conditions found in our solar system, showcasing the unique characteristics of celestial bodies that orbit our Sun, from the scorching heat of Mercury to the frigid expanse of Pluto.
