3.  Plasma is the fourth state of matter Liquid, solid, gas are the other three states Plasma is super-heated ionized gas.

4.  The Earth is 150,000,000 km from the Sun (1 AU).

6.  Core (made of hydrogen and helium) The hydrogen fuses into helium in a process called nuclear fusion. This gives off a lot of heat and energy.

8.  Every second, 700 million tons of hydrogen is converted into helium and the rest of the energy is given off as heat/energy.

9.  The sun is 5-6 billion years old and will last another 5-6 billion years.

10.  The temperature of the core is 15,000,000 ⁰ C and the temperature of the corona is 6,000 ⁰ C.

11.  Photosphere This is the visible layer of the Sun.

12.  It consists of a layer of incandescent gas less than 500 kilometers thick.  It exhibits a grainy texture made up of many small, bright markings, called granules, produced by convection.

13.  Chromosphere

14.  The chromosphere is the first layer of the solar atmosphere found directly above the photosphere.  It is a thin, hot layer of gases a few thousand kilometers thick.  Its top contains numerous spicules, which are narrow jets of rising material.

15.  Corona (only visible during a solar eclipse)  The corona generates the solar winds

16.  Solar wind is a stream of protons and electrons ejected at high speed from the solar corona.

19.  Sunspots are spots that are cooler than the rest of the sun. They show up as dark on chromographs.

21.  Prominences are huge cloudlike structures consisting of chromospheric gases.  Prominences are ionized gases trapped by magnetic fields that come from regions of intense solar activity.

23.  Solar flares are short outbursts of radiation (UV, X-ray and radio waves) that appear above a sunspot.  Auroras, the result of solar flares, are bright color displays of ever-changing light caused by solar flares interacting with the upper atmosphere around the poles.

25.  Over time (as it expands), it will turn into a RED GIANT and then collapse into a WHITE DWARF.

26.  A million earth’s would fit in it.  But it is small by sun standards  It is expanding & getting bigger.  It is 98% of the mass of our Solar System.
