Nation World News Satellites are celestial bodies that revolve around planets and other objects. Satellites are celestial bodies that can monitor regions beyond Earth.
Satellites in space must remain in their orbits around the Earth. This place is also known as Classroom.
Satellites in space are very diverse, including natural satellites and artificial satellites. Here’s the explanation:
Natural satellites are non-man-made space bodies that orbit a planet or other large object.
An example of a natural satellite that we can see is the Moon. However, apart from the Moon there are many natural satellites that are owned by several planets in the Solar System. The following are the names of the satellites on the planet:
- Deimos and Phobos are the two satellites of Mars
- Jupiter has 79 moons including Ganymede, Callisto, Europa and Metis.
- Saturn has 82 satellites and the most famous are Titan and Enceladus.
- Uranus has 27 satellites, five of which are Titania, Oberon, Umbriel, Ariel, and Miranda.
- Neptune has 14 satellites and the most famous are Triton, Nereid, Naiad, Thalassa and Galatea.
natural satellite work
The functions of natural satellites are:
- The center of the satellite’s orbit attracts smaller objects around it to avoid collisions.
- Controls the rotational speed of a planet due to the effect of gravity
- Balancing the seawater cycle that can cause tides
- Reduce the effect of ultraviolet rays so that global warming can be stopped.
- lights up the night
Artificial satellites are satellites made by humans whose purpose is to facilitate all human activities.
Some examples and functions of artificial satellites include Earth observation satellites, ocean observation, communications satellites, weather satellites, military satellites, and space exploration satellites.
Here’s the explanation:
earth observation satellite
As the name implies, an Earth observation satellite is a type of satellite that was built for the purpose of observing the Earth and locating the positions in each hemisphere of the Earth.
Earth observation satellites have been launched by many countries, including:
- Mikhail Lomonosov
ocean observation satellite
This satellite was launched with the aim of observing the position of the oceans on Earth. As we know that ocean is the largest part of the earth.
Therefore it is important to know the position of the sea on the earth. There are many examples of ocean observation satellites that have been launched, including Seasat and Baskhara.
This satellite is the most abundant satellite on Earth. Many countries launch this satellite and more than one because of the need for communication. s
For example, Indonesia has many artificial satellites and almost all of them are communication satellites. Some communication satellites, namely:
- echo 1 and 2
- relay 1
- relay 2
This satellite is used by meteorological, climatological and geophysical agencies to determine the weather conditions of a place so that this information can be received by the public.
It is a satellite that can give warnings about natural phenomena. Some examples of weather satellites are as follows:
This satellite was launched to help the military power of a country to defend itself from enemies. Examples of military satellites include:
- Artificial satellite
space exploration satellite
This satellite was built for the purpose of knowing the conditions and objects in outer space for research purposes. Some examples of space satellites are Sayut and Proton.
