The planets can be divided into two groups: the Earth group and the gas planets and rock-ice dwarf planets group. The Earth group consists of planets with high density and are mainly composed of silicates and metallic iron. In contrast, the gas planets and rock-ice dwarf planets group includes planets found in the Kuiper belt…

Just a short while ago, during our educational years, we were taught that there are a total of nine planets in our solar system. Six of these celestial bodies have been recognized since ancient times, while Uranus was unveiled in 1784 and Neptune in 1846. Ultimately, in 1930, the last planet, Pluto, was discovered. However,…

The moon is the closest celestial body to Earth and has been studied by sages, scientists, and stargazers throughout history. One of the most important aspects of this study is determining the distance between Earth and the moon. The ancient Greeks, Egyptians, and Chinese were among the first to attempt these calculations. However, with the…

The solar system is comprised of the Sun and all celestial bodies that orbit around it due to its gravitational pull.
