Planetary science

Planetary science, also known as planetology, is the scientific study of planets (including Earth), moons, and planetary systems (in particular those of the Solar System) and the processes that form them. It involves a wide range of disciplines such as astronomy, geology, meteorology, and planetary geology. The field of planetary science has grown significantly since the mid-20th century, driven by advances in technology and space exploration. Notable contributions include the discovery of new planetary bodies, the study of planetary atmospheres, and the analysis of extraterrestrial materials. In Hebrew, planetary science is referred to as מדעי כדור הארץ or מדעי פלנטריים. In other languages, it is known as planetenkunde in German, planetologie in French, and planetologia in Spanish, Portuguese, and Italian. Key contextual information includes the use of spacecraft and telescopes for observation, the study of planetary formation and evolution, and the search for extraterrestrial life.
