• Understanding cosmic distances requires specialized units like année-lumière, calculated using light's speed of 300,000 km/s
• The solar system features eight planets divided into rocky terrestrial and gaseous giants
• Cosmic scale ranges from infinitesimally small atomic particles to incomprehensibly large galactic structures
