There are many types of celestial bodies in the solar system, such as planet, stars, and satellites. The difference between planets, stars and satellites lies in their characteristics.

Even though all three are in the same sky and carry out their respective activities, there are still differences. One of them is related to light which only stars have while planets and satellites do not have it.

For example, just satellite which always follows the planet and accompanies it wherever the planet rotates. Meanwhile, stars that fall to Earth actually burn up when they touch the atmosphere.

The differences between planets, stars and satellites in the solar system lie in their characteristics, shape and activity. The following is an explanation of each characteristic, shape and activity of these three celestial bodies.

Planets are the largest objects in the solar system after the sun. The order of the planets from closest to the sun is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

The planets that can be seen with the naked eye (without a telescope) are Mercury, Venus, Mars and Jupiter. In general, planets are grouped based on the earth as the boundary, the size and composition of the materials that make up them, and asteroids as the boundary.

Planets have the ability to rotate around their own axis while simultaneously evolving around the sun. This celestial body cannot emit heat and light. That is why the earth seeks a source of heat and light from the sun by rotating and evolving.

Bintang is a celestial body that can emit light and has heat energy. This celestial body has the mass and energy to burn hydrogen and its isotopes.

Its appearance is scattered in the sky, if you look at it from the planet you will see its light flickering. Its size seems small and not as big as the sun.

Quoting from the book Definitely Can Natural Sciences for Middle School/MTs Class VIIGanesha Operation Team (page 119), satellites are celestial bodies that accompany planets.

Natural satellites are satellites that already exist in the solar system and are not man-made. The planet that has the most satellites is Saturn, while the ones that don’t have satellites are Mercury and Venus.

Satellites have three modes of movement, namely rotating on their axis (rotation), rotating around the planet, and rotating with the planet around the sun. This celestial body does not have its own light source. So it can only reflect light obtained from the sun.

The differences between planets, stars and satellites are quite significant, so the three are easy to distinguish. Even though these three celestial bodies have differences, they all have an important role in the solar system. (glg)
