In today’s astronomy lesson, students explored the solar system and learned about celestial bodies, focusing on the differences between planets and dwarf planets. Key concepts included the classification of planets, with Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune outlined as the eight major planets, while Pluto was discussed as a dwarf planet due to its characteristics. The lesson emphasized that both planets and dwarf planets are spherical and orbit the sun, but dwarf planets do not have a clear orbit. Students also used a telescope as a tool for observing space, reinforcing their understanding of the solar system within the context of the Milky Way galaxy.
