About "9 Planets in the Solar System"
For decades, astronomers recognized nine planets in our solar
system, including the four terrestrial planets and five gas giants. According to NASA, this classification
was established through centuries of astronomical observation, beginning with ancient civilizations and
formalized by the International Astronomical Union. The Smithsonian National Air and Space Museum
documents how Pluto's status as the ninth planet became controversial in the late 20th century due to
discoveries of other trans-Neptunian objects. While Pluto was reclassified as a dwarf planet in 2006, the
concept of nine planets remains culturally significant. This astronomical understanding reflects
humanity's evolving comprehension of our solar system and the ongoing nature of scientific classification.
