DATA AND ATMOSPHERIC INFORMATION OF OUR SOLAR SYSTEM'S PLANETS

 

NOTE:  For brevity, only the original 9 planetary bodies will be mentioned here.  Other than Pluto, "dwarf planets" will not be included. 
  • Mercury...Orbits closest to the sun, but its night is brutally cold.

  • Venus...A greenhouse effect gone wild.

  • Earth...The perfect combination of nitrogen and oxygen, able to sustain many forms of life.

  • Mars...A very thin atmosphere, but did life exist over a billion years ago?

  • Jupiter...Massive and stormy, some evidence suggests that it tried to become a smaller, double-star companion to our sun.

  • Saturn...Its specific gravity is less than water.

  • Uranus...Tilted at an angle of 98 degrees, its poles receive the direct sunlight instead of the equatorial region.

  • Neptune...One of the most dynamic atmospheres in the solar system with the fastest winds.

  • Pluto...Has a highly elliptical and tilted orbit, at times bringing it closer to the Sun than Neptune.
