Sun and Inner Planets
The sun and the inner planets are some of the most interesting objects in our solar system! The inner planets include the Sun, Mercury, Venus, Earth,and Mars.
Definition: any of the planets Mercury,Earth Venus, and Mars whose orbits are within the asteroid belt
Earth is the planet on which we live on and is known as the world
Mercury: the planet that is the closest to the sun.
Sun- The star that is the central body
of the solar system around which the planets revolve and receive light and heat from.
-Diameter is 4223 miles
-Distance from sun is 141.6 million miles
-Layers/Composition: crust, mantle, and the core
-Atmosphere is made up of carbon dioxide, notrogen, and argon.
-Past Exploration: include Viking 1 was launched by the USA in August 20,1975
-Future Exploration: include Marven from Usa will be launchedin November 2013 and Insight will be launched by USA in March of 2016
-NASA is thinking that Mars used to have water, so that must mean that Mars used to have some kind of life on Mars
-Mars kind of like Earth, has a warm wet ground
-Mars has huge mountains exactly like Earth does
-Like Earth, Mars has seasons
-Mars has deeper valleys than the Grand Canyon!!
-Is the fastest moving planet in our solar system as well as the smallest
- Is one of the terrstrial planets
-It has no moons
-Mercury's atmosphere is constantly being replenished
-Composition and layers: crust, mantle, core, and interior resembles Earth
-The force of gravity is one third as strong as Earth
Past Exploration: Mariner 10 that was lanched by USA in the years 1974-75, the Messenger, aslo launched by the USA was lanched in the years 2004,2008-9 and went into orbit in 2011
Future Exploration: The Bepi Colombo will be launched by Europe/Japan in 2014
-Has a diameter of 12,100 km
- Venus is 107 million km away from the sun
- It spins backwords
-It is 900 degrees Farenheit
-It has the most circular orbit
-The year is almost 19 of our Earth days
-It has the longest day of all planets
- Layers: crust, mantle, and the core
-Atomosphere is made up of carbon dixoide, nitrogen, sulfuric acid, and traces of other elements
-Past exploarion: The last space craft was sent by N.A.S.A called Mariner 2 sent on August 27, 1962
-Future exploration: Venus Express, sent by the European Space Agency, is suppose to arrive in 2015.
The planet that is second in order from the sun.
-Closest planet to the sun
-Known as Apollo or Hermes
-Diameter of 4,868 kilometers
-46 million km away from sun
- Includes large iron core, resembles Earth
-Second densest major body in solar system
-Atmoshere contains hydrogen, helium,sodium,oxygen,calcium,and potassium
- Hot and dry
-Atmoshere is constantly replenished
-Gravity is one third as strong as Earth's
-Past Explorations: Mariner, launched by the U.S 1974-1975, Messenger, launched by the U.S in 2011,
-Current Explorations: Bepi Colombo, launched by Europe/Japan
-The sun is a star that is the center of the universe
-The sun is the closest star to Earth
- It's diameter is 870,000 miles
-Light from the sun takes 8 minutes to reach Earth
-Layers of the sun: the core, radiation zone, convection, photosphere, and the chromosphere
-The Sun's core is about 136,000,000degrees Celcius!
- The atmosphere is made up by the corona, photosphere, and chromosphere
-The sun makes up about 99.86% of the Solar System's Mass
-The sun's diameter is 110 times wider than Earth's!
some include Soho, lanched by USA in 1995, Gensis, also launched by USA in 2001, and Trace launched by USA in 1980

-The planet on which we live on
-Known as the world
-Only planet with living things
-Diameter of 7,926 miles
-92.9 million away from the Sun
Layers of Earth: crust,mantle,outer core,and inner core
-Atmoshere is made of: nitrogen, oxygen,argon,carbon dioxide, helium,hyrogen,and methane
-Layers of the atmoshere: thermoshere, mesoshere, stratoshere,and troposhere
-Past exploration: NOAA 17, launched by America in 2002,Golden Eye, launched by France in 1995,
-Current exploration: LOMPOC, launched by America in 2013
Definition: the fourth outermost planet of the Terran-Solar-System
