Facts about the Earth

EARTH

1. ​​ EARTHS PLACE IN THE SOLAR
​    SYSTEM
​     Earth is the 5th largest planet in our
     solar  system and is the 3rd planet
     from  the sun.

2. ​EARTH ORBITS AROUND THE 
    SUN
​     Like all planets, Earth orbits around
     the Sun which is at the center of
     the solar system. On a grander scale
     our solar system orbits the center
     of the galaxy.

3. THE BLUE PLANET
     71% of the Earths surface is water.
     96.5% of that water is salt water.
     The other 3.5% is fresh water in
     rivers, lakes, and locked into
     v arioius forms of our water cycle.

4. EARHT IS MOVING FAST
     The Earth moves at an amazing 
     speed of 67,000 miles/hr. If we
     do the math that means the Earth
     travels approximately 586,920,000
     miles in one year.

5.  EARTHS SMALL SIZE PACKS A 
    BIG PUNCH
    For being a relatively average size
     planet we pack a powerful punch
     when it comes to Earths density.
     Out of our entire solar system Earth
     has the highest density of all the
     planets.

6.  EARTH HAS NOT ALWAYS BEEN
    OURS
     Humans have not always been the
     dominant species on Earth. The 
     dinosaurs ruled the planet for over
     150 million years before we came 
     along.

7. ​WHICH WAY IS NORTH
     It seems that the Earth changes it's
     magnetic poles every 200,000 to 
     300,000 years. North becomes
     South and South becomes North.

​8. OUR DISTANCE FROM THE SUN
    The Earth is 92,955,820 miles from 
     the Sun. You can also say that the 
     Earth is 1 AU from the Sun. AU
     stands for Astronomical Unit which
     is equivelant to the distance of the 
     Sun from the Earth.

9. OUR NATURAL SHIELD
     Earth's atmosphere acts as a shield,
     protecting us from most of the
     Sun's  radiation, but not all of it.

The Earth is unique in many ways and the reason for this is greatly due to it's position in our solar system. Earth is located in what is called the habitable zone. This is a zone or rather distance from the Sun that a planet can orbit a star and maintain temperatures not to cold or hot while retaining water in a liquid form on its surface such as oceans, lakes, rivers, etc..

Since the launch of the Kepler space telescope in 2009 in has found more than 2,000 exo-planets. Over 30 of those are located within the habitalzone.

In July of 2015 NASA confirmed the existence of an exo-planet in the habitable zone that is very Earth like. The planet is called ​​​Kepler-186f
