SOLAR SYSTEM

Pluto			Diameter	3,040 Kilometer
			Moons	1
			Avg.Distance to Sun	5,865.5 million KM
			Time to Orbit the Sun	248 Years
			Facts	This Planet is the farthest, the smallest, the darkest, the coldest and arguably the strangest. It follows the most elongated and tilted orbit in the solar system. Its moon, Charon, is nearly half its size - appears like a bi-planet. NASA used a new infra-red telescope, has learned that Pluto is shrouded in frozen nitrogen- not methane as once thought. Nitrogen makes 78% of the air.

Neptune			Diameter	49,000 Kilometer
			Moons	8
			Avg.Distance to Sun	4,497 million KM
			Time to Orbit the Sun	165 Years
			Facts	It is denser & little smaller than Uranus. Its Atmosphere appear blue, with quickly changing white clouds often suspended high above an apparent surface. Atmosphere constituents are mostly hydrocarbon compounds. It Emits about 2.3 times more energy than it receives from the sun and the Aurora phenomenon was noticed by Voyager II.

Uranus			Diameter	52,096 Kilometer
			Moons	17
			Avg.Distance to Sun	2,852.8 million KM
			Time to Orbit the Sun	84 Years
			Facts	Waterly Uranus is the only planet that lies on its side. One pole, than the other, faces the Sun as it orbits. Voyager-I found nine dark, compact rings around the planet and a corkscrew-shaped magnetic field that stretches millions of kilometers.

Mars			Diameter	6,755.2 Kilometer
			Moons	2
			Avg.Distance to Sun	225.6 million KM
			Time to Orbit the Sun	687 Days
			Facts	The Viking probes failed to Beneath its thin atmosphere. Mars is barren, covered with pink soil and boulders. Long ago it was active, the surface is marked with dormant volcanoes and deep chasms where water once freely flowed.

Venus			Diameter	12,032 Kilometer
			Moons	None
			Avg.Distance to Sun	107.52 million KM
			Time to Orbit the Sun	225 Days
			Facts	Earth's twin in size and mass, sparingly hot Venus is perpetually veiled behind reflective sulfuric-acid clouds. Probes and radar mapping have pierced the clouds and carbon-dioxide environment to reveal flat, rocky plains & signs of volcanic activity.

Mercury			Diameter	4,849.6 Kilometer
			Moons	None
			Avg.Distance to Sun	57.6 million KM
			Time to Orbit the Sun	88 Days
			Facts	Tiny Mercury, slightly larger than Earth's moon. Races along its elliptical orbital 1,76,000 kilometer per hour. A speed that keeps it from being drawn into the Sun's gravity field. The crated planet has no atmosphere, days are scorching hot and nights, frigid.

Earth			Diameter	12,732.2 Kilometer
			Moons	1
			Avg.Distance to Sun	148.8 million KM
			Time to Orbit the Sun	365 Days
			Facts	Uniquely moderate temperature and the presence of oxygen and copious water maker Earth the only planet in the solar system to support life.

Jupiter			Diameter	1,41,968 Kilometer
			Moons	16
			Avg.Distance to Sun	772.8 million KM
			Time to Orbit the Sun	11.9 Years
			Facts	Two Pioneer space probes photographed the Great Red Spot on the Solar system's largest planet. Voyagers I and II later showed it is an enormous eddy in the turbulent cloud cover. Earth the only planet in the solar system to support life. They also spotted dusty rings, three new moons and volcanoes on the Moon.

Saturn			Diameter	1,19,296 Kilometer
			Moons	20 or more
			Avg.Distance to Sun	1,417.6 million KM
			Time to Orbit the Sun	29.5 Years
			Facts	Voyager I found that the celebrated rings of the golden giant Saturn are composed of thousands of rippling, spiraling bands just 100 feets thick. The moon Titan has a nitrogen atmosphere and hydrocarbons.

Sun			Diameter	13,84,000 Kilometer
			Statellites	9 Planets
			Age	4.5 billion years
			Facts	A rather ordinary, middle age star, the gaseous sun may reach a temperature of 27-millon degrees Celsius at its core. Its 11 years cycle is now approaching a solar maximum, a period marked by frequent sunspots and flares. On Earth, some radio waves will be disturbed and the amazing sky streamers called Northern Lights will appear.
