planets and solar system

planet	Special characteristic	Rotation and revolution time	Important  properties	Satellite system
mercury	Smallest and inner most planet .It has no atmosphere. It has a cratered surface, much like the moon.	Rotation: 58 days Revolution: 88 days( fastest  revolution in the solar system)	It has maximum diurnal range of temperature.	No satellite
venus	Also called as veiled planet. Know as evening and morning star as it is seen in the east in morning and in west in the evening. It is the brightest object in solar system because of almost 70% albedo. It contains 90 to 95% co2. The night and day temperature almost the same.	It has the slowest rotation speed. It has almost equal rotation and revolution. Rotaion : (clockwise) 257 days and revolution : 224.7days.	Rotates from east to west unlike the other planets. It is the hottest  planet.	No satellite
Earth	The earth is neither too hot nor too cold. It has goldilock zone. It is called as the blue planet, due to the presence of water.	Rotation: 24 hours Revolution: 365 days and six hours.	It is the densest of all and is unique for the presence of higher forms of life.	Moon is the only natural satellite.
mars	Called as red planet. It has a thin atmosphere comprising of nitrogen and argon.	Rotation : 24.6 hours (almost equal to earth) Revolution: 687 days.	It is marked by dormant volcanoes. Nix olympia is the highest mountain. Which is three times higher than mount Everest.	Two satellites: phobos and deimos.
jupiter	It is the largest planet in solar system with a mass 2.5 times greater than the combined mass of all the remaining planets ,satellites, and asteroids put together. It contains hydrogen , helium, methane, and ammonia. A greater red spot is detected on it.	Fastest rotational velocity (9.8 hrs)	It is too massive to solidified as a planet, but not massive enough to develop nuclear fusion and become a star. It gives off more energy than it receives from the sun, because of the heat inside.	It has 67 satellite. some of prominent satellites  are: Europa,callisto and gannymede.
Saturn	It the second largest planet and is surrounded by set of eight rings, which are made up of primordial dust and ice particles.	Rotation: 10.3 hours Revolution in 29.5 years.	It has the least density of all the satellites.30 times less dense than earth.	It has 62 satellites, the largest being titan.
Uranus	It is unique as its axis of rotation is inclined at only 98 degree to its orbital plane.	Unlike the others, which spin on their axis, Uranus actually rolls, apparently from north to south.	Surrounded by a system of 9 faints rings.	It has 27 satellites. The prominent are Miranda, ariel ,etc.
Neptune	It is a penultimate planet, has a dynamic atmosphere, which contains an earth sized blemish called the great dark spot that is reminiscent of jupiter’s great red spot.	Rotation : 15.7 days and revolution 165 years.	It has five faint rings. It appears as greenish star.	It has 14 satellites. The prominent are triton and Nereid.
