Our Sun A medium sized star. Our Sun Our sun is a typical medium sized star. A star is a hot ball of plasma that shines because nuclear fusion is taking.
The Sun. 99% of the matter of the solar system is in the Sun. The Sun is an Average Star (main sequence star) The sun is not a Binary Star. (most stars.
Notes The Sun. Stars an object that produces it own energy, including heat and light.
Our Sun. Why do we care about the Sun... - Light, heat, life - Space weather solar wind (1,000,000 mph) flares (UV, x-ray radiation) disturb Earth's magnetic.

Sun & Solar System Structure of the Sun:

Sun & Solar System Structure of the Sun: Core: where nuclear fusion occurs -this creates the immense heat (15 millionoC)

Sun & Solar System Structure of the Sun: Core: where nuclear fusion occurs -this creates the immense heat (15 millionoC) Radiative Zone: energy radiates through this zone on its way outward Convective Zone: heat moves outwards by convection while cooler matter moves back towards the core

Sun & Solar System Structure of the Sun: Core: where nuclear fusion occurs -this creates the immense heat (15 millionoC) Radiative Zone: energy radiates through this zone on its way outward Convective Zone: heat moves outwards by convection while cooler matter moves back towards the core Photosphere: where light and other forms of radiation escape (5500oC) Atmosphere: divides into two layers: Chromosphere: inner atmosphere (65,000oC) Corona: outermost layer -extends millions of kilometres into space

Sun & Solar System Surface of the Sun: Sunspots: dark spots appearing on the Sun's surface that are cooler than the area surrounding them -caused by disturbance in the Sun's magnetic field Solar flares: gases and charged particles expelled above an active sunspot Solar prominences: low-energy gas eruptions from the Sun's surface that extend thousands of kilometres into space

Sun & Solar System Surface of the Sun: solar flare

Sun & Solar System Surface of the Sun: sunspots

Sun & Solar System Surface of the Sun: solar prominence

Sun & Solar System Sun's Effects on Earth: Aurora Borealis: a display of shifting colours in the northern sky caused by solar particles colliding with matter in the Earth's upper atmosphere Aurora Australis: simultaneous display near the South Pole

Sun & Solar System Sun's Effects on Earth: Communication Disruptions: particles ejected by the sun in solar flares can damage satellites around Earth Radiation Hazards: airplane travel can dose a person with as much radiation as an X-ray
