Memory Game Astronomy Memory GameOnline version Astronomy Memory Game by Grant Studios Sunspots are cooler than the plasma around them In the convection zone plasma rises as it heats up then falls 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 In the core is where fusion of hydrogen occurs in the sun Atoms are combined into heavier elements through the process called Nuclear Fusion A planets revolution is the slowest when furthest from the sun Atoms are combined into heavier elements through the process called Nuclear Fusion In the core is where fusion of hydrogen occurs in the sun 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 Hydrogen and Helium make up most of the suns mass In the convection zone plasma rises as it heats up then falls The "r" in Keplers third law stand for Radius Sunspots are cooler than the plasma around them Hydrogen and Helium make up most of the suns mass A planets revolution is the slowest when furthest from the sun The "r" in Keplers third law stand for Radius According to Keplers first law planets orbit in a Ellipse The "p" in Keplers third law stands or Orbital Period The "p" in Keplers third law stands or Orbital Period According to Keplers first law planets orbit in a Ellipse
