Artificial Satellites in Space

Introduction to artificial satellites in space:

Satellites are the objects in space that orbit around planets. The artificial satellites are the objects that are made by humans and launched into the space. They orbit around the corresponding planet.

I like to share this What is Average Atomic Mass with you all through my article.

Artificial satellites in space:


Artificial satellites are man-made objects that orbit around a planet in space. Most satellites are built to orbit around the Earth. These satellites are different from the natural satellites like moon. Natural satellites are formed naturally during explosion or other phenomenon in space.

The artificial satellites are designed with a purpose. Some satellites like the Space shuttle and the international space station have men in them.

These artificial satellites are used for several purposes- for earth studies, space studies, for communication, military support, and weather observation, for space observations, for imaging the earth and to record the special changes as well as changes on the earth surface. While some satellites are designed for a specific purpose, most others perform a host of activities.

Live television shows have become a possibility due to communication satellites. These satellites perform relay transmission of television signals, radio signals and messages.

The satellites are launched through rockets. The aerospace companies build the satellites. Based on the purpose of artificial satellites, they are launched into different orbits. The ones closer to the earth are low orbiting satellites. A satellite orbits altitude is the guiding factor in determining how long a satellite will stay in space and orbit around a planet.

The first satellite ever launched into the space is explorer 1 that was launched by USA on Jan 31st of 1958. This satellite was responsible for the historic discovery of the presence of high energy electrons and protons in the planets Jupiter and Saturn. Since 1958 about 5000 satellites have been launched by several government and scientific research agencies and even by some private companies like Google.

Is this topic net force formula hard for you? Watch out for my coming posts.

Conclusion for artificial satellites in space:


Artificial satellites are definitely a state of the art invention of mankind. They are man-made objects launched into the space through rockets. There are several application areas of artificial satellites in communication, scientific research, weather observation, earth imagery and many more.
