Memory Astronomy Memory GameVersión en línea Astronomy Memory Game por Grant Studios Atoms are combined into heavier elements through the process called Nuclear Fusion The "p" in Keplers third law stands or Orbital Period In the core is where fusion of hydrogen occurs in the sun The "r" in Keplers third law stand for Radius In the convection zone plasma rises as it heats up then falls The "p" in Keplers third law stands or Orbital Period A planets revolution is the slowest when furthest from the sun Atoms are combined into heavier elements through the process called Nuclear Fusion A solar prominence (also known as a filament when viewed against the solar disk) is a large, bright feature extending outward from the Sun's surface A solar prominence (also known as a filament when viewed against the solar disk) is a large, bright feature extending outward from the Sun's surface Sunspots are cooler than the plasma around them In the convection zone plasma rises as it heats up then falls The "r" in Keplers third law stand for Radius According to Keplers first law planets orbit in a Ellipse Hydrogen and Helium make up most of the suns mass According to Keplers first law planets orbit in a Ellipse In the core is where fusion of hydrogen occurs in the sun Hydrogen and Helium make up most of the suns mass Sunspots are cooler than the plasma around them A planets revolution is the slowest when furthest from the sun
