In diameter: 1,392,648 km

109x the Earth

Mass: 2 x 10^30th

330,000x the Earth


5/16

Density of the Sun

1.410 g/cm^3

In the middle of all planets

Including moons

Most Dense: Earth 5.515 g/cm^3

Interior Composition:

91.2% hydrogen8.7% helium

0.078% oxygen0.043% carbon0.0088% nitrogen0.0045% silicon0.0038% magnesium

0.0035% neon0.0030% iron0.0015% sulfur


7/16

Internal Layering:

Inner Core: 0.3 Solar Radii,

15x10^6 K, Region of energy

generation

Radiative Zone: 0.3-0.6 Solar

Radii, 6x10^6 K, Where

energy transport is by

radiation flow

Convection Zone: 0.6-1.0

Solar Radii, 1x10^6 K, Where

energy transport is by

convection shells


8/16

Atmosphere:

Photoshpere: 100 km,

6,000 K, surface where

photons are emitted

Chromosphere: 2,000 km,

30,000K, middle of

atmosphere

Corona: 10^6 km, 1x10^6

K, where solar wind

orginoinates, extends

much farther into space


9/16

Magnetic Fields:

Has a very strong magnetic field

Causes all the planets to orbit it

Magnetic rings form in corona

Magnetic field several times the size of Earths magnetic field


10/16

Rotation and Revolution:

The Sun does not revolve

Planets revolve aorund sun

Does rotate every 25 days

Proof: Sun spots, show side and cycle of sun


11/16

Evidence of Water and Fluids

Yes

Located in Sunspots

Sunspots can be 4,760 F

Water forms and evaporates

Forms water vapor (consists of Oxygen + Hydrogen)


12/16

Space Missions

2017 we will

NASA will send two probes

Will sit 70 million miles from sun to not melt

Challenger would have observed suns longitude and latitude


13/16

Evidence of Life

NONE


14/16

Plate Tectonics:

No plate tectonics

The Sun does not have a Solid surface

Does have a core


15/16

Interesting Facts:

The suns layers go from cooler to hotter

The sun accounts for 99.8% of our solar systems mass

The sun has gone through half its life

If it exploded, the explosion would contain all the energy it

produced throughout its life (another big bang)The sun is large but very small (a dwarf star)In 1 billion years the sun will be too hot for life on earthEach layer rotates at a different speed
