Study Notes
- The solar system consists of the Sun, planets, moons, rings, asteroids, comets, and dust, all formed about 4.5 billion years ago from a cloud of gas and dust.
- Decades of observation and spacecraft exploration have provided a wealth of information about the solar system.
- Spacecraft missions like Voyager, Pioneer, Curiosity, and Pathfinder have allowed for close-up study of planets, moons, asteroids, comets, and more.
- Planetary astronomy is unique as it enables researchers to virtually travel to and study various objects in the solar system.
- The exploration of the solar system has revealed fascinating details about dwarf planets, moons, ring systems, asteroids, and comets.
Explore the formation of the solar system, including the Sun, planets, moons, asteroids, comets, and dust. Learn about the condensation of material from a gas and dust cloud around 4.5 billion years ago.
