| 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.
