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