The general evolution of planets in the Solar System is discussed with a focus on the structure and history of Venus compared with the Earth. The history of the planets of the terrestrial group has been similar and included at least six correlated stages. Many common features the terrestrial ...

In space, 93 million miles away from planet Earth lies the Sun, emitting ultraviolet wavelengths to the Earth 's surface and heating up our planet. The Sun provides the Earth with energy known as solar energy (Cofey, 2010). When the Sun’s energy has reached the Earth 's atmosphere by...
Planet demographics reveal a puzzling lack of worlds in a certain size range throughout the galaxy 行星人口统计揭示了银河系中某些特定大小行星的奇怪缺失. 作者:Dakotah Tyler; 编辑:Clara Moskowitz. For centuries our solar system was the only planetary system known to humans. We had no proof other...
“Earth-chauvinist” term, but it is so widely used that we bow to tradition.) Among the terrestrial planets, Earth and Venus have experienced the most geological activity over their histories, although some of the moons in the outer solar system are also surprisingly active. In contrast, our...
1 The formation of our solar system was highly chaotic: planet-sized objects formed from coalescing gas and dust and were destroyed in collisions, only to re-form later. Some of these objects fell into the Sun. Some orbited the Sun and became the planets we know today. Others were cast ...
(type G) stars. Nonetheless, in the solar system, liquid water also exists out of the HZ, e.g. in Enceladus and Europa, moons of Saturn and Jupiter, respectively, as a subglacial ocean due to tidal heating. Ojha et al.1modeled the evolution of ice sheets and the conditions that ...
Studies of meteorites add much to our understanding of the age of the solar system and the nature of the building blocks that makes up the planets. The earliest formed fragments of the solar system (i.e., calcium–aluminum inclusions), found in some of these chondrites, are high ...
Abundances of the highly siderophile elements (HSEs) in silicate portions of Earth and the Moon provide constraints on the impact flux to both bodies, but only since ~100 Myr after the beginning of the Solar System (hereafter tCAI). The earlier impact flux to the inner Solar System remains...
