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