The Solar System

Nebula Theory (our solar system) The solar system started from the spinning and condensing of a cloud of dust and gas. The greatest matter formed the sun with the remaining becoming the planets.

Inner Planets Terrestrial planets –Mercury –Venus –Earth –Mars Formed as small rocky material nearest to the protostar(our sun) cooled.

Jovian (outer planets) Jupiter Saturn Uranus Neptune

Perihelion- when the planet is closest to the sun Aphelion- when the planets are farthest away Planets orbit in ellipses

Sun Features: Core –nuclear fusion occurs Radiative zone- energy moves outward in waves

Convection zone- warmed gases rise and cool gases sink Photosphere- the visible surface of light

CHROMOSPHERE Above the photosphere Reddish in color contains spikes of gas called spicules that rise through it

Sunspots: are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. –They are caused by intense magnetic activity, which inhibits convection

CORONA Outermost atmosphere of the sun Seen only during a total solar eclipse Very hot but thin

Sunspots: are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. –They are caused by intense magnetic activity, which inhibits convection

Solar Winds Corona prevents most particles from exiting the sun. However, some Ions/ particles escape as Solar Winds. Causes Auroras (northern lights).

SOLAR FLARES- Large Eruptions of Gas Increases Auroras

Prominences: large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape.

A coronal mass ejection (CME): is a massive burst of solar wind and magnetic fields rising above the solar corona or being released into space. * Can only see corona during an eclipse

An aurora is a natural light display in the sky –Auroras are caused by charged particles, mainly electrons and protons

Increased solar flares activity can interrupt communication systems on earth

CORONA SOLAR FLARES SUN SPOTS PROMINENCE SPICULES CHROMOSPHERE PHOTOSPHERE CONVECTION ZONE RADIATIVE ZONE CORE

Asteroids are small metallic rocks that orbit the sun between Mars and Jupiter

METEORS A meteoroid from space that burns up in our atmosphere

Meteorites Chunks of rock that have hit the earth’s surface

DIRTY SNOWBALL Composed of dust, gas, and ice Has a tail as it approaches the sun COMETS
