                    Our Solar System
   Our solar system consists of:
       A Star
            Sun
       9 Planets
            Mercury
            Venus
            Earth
            Mars
            Jupiter
            Saturn
            Uranus
            Neptune
            Pluto
       Comets and Asteroids
                                        Sun
   The sun is a star at the center of the
    solar system.

   The sun is the largest object and
    contains almost 98% of our solar
    systems mass.

   The sun’s outer temperature is around
    11,000 degrees Fahrenheit.

   The sun has been active for about 4.6
    billion years and has enough fuel to
    keep being active for around another 5
    billion years.
Mercury
      Mercury is the plant that is closest to the
       sun.

      Mercury is the second smallest planet.

      The diameter of Mercury is about 40%
       smaller then Earth and 40% larger then
       the Earth’s moon.

      Mercury’s surface is a series of rolling,
       dust covered hills.

      Mercury rotates 1 ½ times every day.
       Because of this, one day on Mercury is
       176 Earth days.

       of Mercury
                                        Venus
   Venus is the second planet from the
    sun.

   Venus is covered by thick swirls and
    clouds.

   Venus is similar in size to Earth

   The temperature on Venus is about 900
    Degrees Fahrenheit

   A year in Venus is 243 Earth days and a
    day is 225 Earth days. In Venus, a year
    is shorter then a day.

   Venus rotates in the opposite direction
    from all of the other planets.

    of Venus
Earth
      Earth, the planet we live on, is the third
       planet from the sun.

      The Earth takes 365.256 days to circle
       the sun and 23.9325 hours for it to
       rotate one time.

      The Earth rotates on its Axis which
       causes the seasons.

      The Earth is only a few hundred
       kilometers larger then Venus.

      Earth is the only planet that is known
       to support life.

      Earth Profile: This is a link to the
       profile of Earth.
                                         Mars
   Mars is the fourth planet from the sun.

   The rocks, soil, and sky on Mars look
    pink. The surface has craters and
    canals.

   The average temperature on Mars is
    -81 degrees Fahrenheit.

   Mars takes 24.6229 hours to rotate
    one time, and 686.98 days to circle
    around the sun.

   Mars Profile: This is a link to the profile
    of Mars.
Jupiter
       Jupiter is the fifth planet from the sun.

       Jupiter is the largest planet in our solar
        system.

       Jupiter is circled by what is called
        Jupiter's ring. This ring consists of
        three rings.

       Jupiter takes .41352 to rotate and
        circles the sun in 4332.71 days. (11.86
        Earth years:1 Jupiter year)

        of Jupiter.
                                      Saturn
   Saturn is the sixth plant from the sun.

   Saturn is the second largest planet in
    our solar system.

   The poles of Saturn are flattened
    because of its fast axis speed.

   A day in Saturn is 10 hours and 39
    minutes and each year is 29.5 Earth
    Years.

   Saturn has over 1,000 rings around it.

   Saturn Profile: This is a link to the
    profile if Saturn.
Uranus
      Uranus is the seventh planet from the
       sun.

      Uranus is the third largest planet in the
       solar system.

      One day is 17 hours and 14 minutes
       and a year is 84.1 Earth years.

      Uranus has a blue-green color
       because of Methane gas.

      Uranus is unique because it is tipped
       on its side.

      Like Jupiter and Saturn, Uranus also
       has rings around it.

      Uranus Profile: This is a link to the
       profile of Uranus
                                   Neptune
   Neptune is the eight planet from the
    sun.

   One day in Neptune is 16 hours and
    6.7 minutes and a year is 165 Earth
    years.

   If Neptune were hallow, it could fit
    nearly 60 Earths inside of it.

   Neptune is the last planet with a set of
    rings. They are a set of four narrow
    and faint rings.

   Neptune Profile: This is a link to the
    profile of Neptune.
Pluto
       Pluto is the ninth and last planet from
        the sun.

       Pluto is the only planet that has not
        been visited by a spacecraft.

       It takes Pluto 249 years to orbit the
        sun and it takes 6.387 days to rotate.

       Even though it is the farthest from the
        sun, Pluto is actually closer to the sun
        then Neptune for 20 years out of the
        249 year orbit. This is because of the
        orbit pattern.

        of Pluto.
            Asteroids and Comets
   Asteroids (bottom picture) are rocky
    and metallic objects that circle the sun
    but are to small to be called planets.

   Asteroids range in size from a
    diameter of 1000 kilometers to
    pebbles.

   “Comets are small, fragile, irregularly
    shaped bodies composed of a mixture
    of non-volatile grains and frozen
    gases.” (Calvin J. Hamilton)

   Comets develop luminous tails as they
    approach the sun. (pictured on top)
