Perhaps During this we see on satellite images like the following picture, then we will think that the satellite is only slightly above there




Satellites are objects that orbit other objects with a certain period of revolution and rotation. There are two types of satellite satellite that is natural and artificial satellites.
Here are the Types of Satellite:
* Satellite astronomy* Satellite communication* Earth observation satellite* Satellite navigation* Spy satellite* Satellite solar power* Space stations* Satellite weather* Satellite miniature
Types of Satellite Orbit:Many satellites are categorized on the height of its orbit, although a satellite can orbit at any height.
1. Low Orbit (Low Earth Orbit, LEO): 300 - 1500km above the earth's surface.
2. Orbit Medium (Medium Earth Orbit, MEO): 1500-36000 km.
3. Geosynchronous orbit (geosynchronous orbit, GSO): approximately 36,000 km above the Earth's surface.
4. Geostationary orbit (geostationary orbit, GEO): 35 790 km above the Earth's surface.5. High Orbit (High Earth Orbit, Heo): above 36 000 km.
Orbit following is a special orbit which is also used to categorize satellites:
* Molniya orbit, a satellite orbit with the orbital period of 12 hours and inclination of about 63 °.* Orbit Sunsynchronous, satellite orbit with high inclination and particular that always crossed the equator on the same local clock.* Polar orbit, the satellite's orbit that crosses the polar
See how many types of satellites that make sense whether the photo-satellite photos that we see there are only a few satellites are
In fact:

Launched the first artificial satellite to orbit Earth was Sputnik 1, launched on October 4, 1957 by the Soviet Union after the more advanced technology makes rapidly growing satellite launchNext. Up to January 19, 2000, the number of man-made satellites have been launched to Earth is 5159 gorbit satellite.
And until now based on existing data in the catalog UCS version October 1, 2009, the number of satellites that function is 918 units.From the latest data obtained from Space-Track (edition May 26, 2010 at 01:21:34 GMT) note that the number of artificial celestial bodies larger than 10 cm which is currently circling the earth is
15,616 units (increase compared to last month's 42 )
Satellite (function not working) = 3437
Rocket Body = 1864
Flakes = 10 219
Total = 15,520 satellite
How many that?
