Jakarta –
Stars and satellites is part of the solar system. According to the Ministry of Education and Culture’s website, the solar system is a system of interaction of celestial bodies with the sun as the center and the planets that surround it.
Although both are part of the solar system, stars and satellites have different meanings. The following is a complete explanation of the meaning and characteristics of stars and satellites.
What are stars? According to the Big Indonesian Dictionary (KBBI), a star is a celestial body consisting of burning gas like the sun, especially visible at night. Meanwhile, according to the NASA website, stars are the most widely known astronomical objects and represent the most basic building blocks and galaxies.
Meanwhile, according to the Kominfo website, a satellite is a celestial body that moves around a planet in a circular or elliptical path. Satellites move in orbit around planets or stars.

Star Features
Stars can emit their own light. Stars are also called luminous gas balls, most of which are composed of hydrogen and helium. The two materials are brought together by gravity with high temperatures which then produce energy.
Each star has a different size and amount of energy. We can determine the energy of a star by looking at the color of its light. Stars with white or blue light have a high temperature, while stars with an orange or red color have a low or cooler temperature.
Types of Satellites
There are two types of satellites, namely natural satellites and artificial satellites. What is the difference between a natural satellite and an artificial satellite? Here’s the information.
Natural satellites: Satellites of natural origin. An example is the moon which is a natural satellite for the earth, while the earth and other planets in the solar system are also natural satellites of the sun. Artificial satellites: Satellites made by humans and placed in an orbit using launchers for certain functions. Its function can be communication, weather monitoring, mapping, and so on. Examples of artificial satellites are Palapa, Garuda, Indostar, Telkom, and others.
Differences in the Benefits of Stars and Satellites
Stars are luminous celestial bodies. The shining starlight can illuminate the darkness of the night sky. In addition, stars can also show east, west, south, air by observing the constellations.
Meanwhile, the benefits of satellites depend on the types. The following are the benefits of natural satellites and artificial satellites.
Attracts small celestial bodies around it, so that collisions occur in the center of the satellite orbit. Reflects light from surrounding stars, so the planet has light at night. Balances the ocean water cycle which can cause ebb and flow of sea water. Reduces the effects of ultraviolet radiation, thus avoiding the causes of global warming. Capture space conditions and images to detect astronomical events. Predict the weather and climate on earth. around it. Makes it easier for humans to find the location of a certain place through a GPS signal receiver.
Thus the information difference between stars and satellites. Hope it is useful!
