Dwarf planet

Classical architecture refers to a style of architecture that originated in ancient Greece and Rome, which has influenced Western architecture for centuries. This style is characterized by its emphasis on symmetry, geometry, and a set of well-defined rules known as the "classical orders" of architecture. These orders—Doric, Ionic, and Corinthian—are defined by specific types of columns and entablatures, each with distinctive proportions and detailing. Classical architecture often includes the use of pediments, architraves, and friezes, featuring sculptural reliefs depicting mythological scenes.

The principles of classical architecture were revived and adapted by European architects during the Renaissance, leading to the Neoclassical movement in the 18th and early 19th centuries. This revival was driven by a renewed interest in the ancient world, spurred by archaeological discoveries and a philosophical shift towards rationalism and symmetry in art and architecture.

Classical architecture has left a lasting legacy on many public buildings, such as courthouses, museums, and government buildings around the world. Its principles of order, harmony, and beauty continue to influence modern architecture, demonstrating the timeless appeal of classical ideals.

A dwarf planet is a celestial body that orbits the Sun and has enough mass to assume a nearly round shape but has not cleared its orbital path of other debris. The International Astronomical Union (IAU) introduced the term in 2006, when it reclassified Pluto from a planet to a dwarf planet, sparking widespread debate and interest in the definition of a planet. Dwarf planets are considered to be a subclass of planets, distinct from the "classical" planets and smaller "small Solar System bodies" like asteroids and comets.

The most well-known dwarf planets in our solar system include Pluto, Eris, Haumea, Makemake, and Ceres, the latter of which is located in the asteroid belt between Mars and Jupiter. These bodies share common characteristics, such as being in hydrostatic equilibrium (their gravity is strong enough to maintain a roughly spherical shape), but they differ significantly in their composition, atmospheres, and orbital dynamics.

The discovery and study of dwarf planets have important implications for our understanding of the formation and evolution of the solar system. They represent a diverse group of objects that can offer insights into the processes that shaped the early solar system and the transition zone between rocky planets and gas giants.
