KOMPAS.com – The solar system is the sun and a collection of celestial bodies that surround it such as planets, moons, satellites, asteroids, meteoroids, and comets.
In addition, there are several space events that we can study and observe, for example, solar eclipses.
Here’s the explanation:
Solar eclipse
A solar eclipse is an event where the sun is covered by the moon because the sun, moon and earth are in a straight line which results in blocking the sun’s light from reaching the earth.
Reporting from the 2020 Middle School/MTs UNBK Question Pattern Disassembly Book (2019) by MFAtsnan, here’s a picture of the solar eclipse:

Various solar eclipses
In addition, there are three types of solar eclipses, namely total solar eclipse, partial solar eclipse, and annular solar eclipse.
The following is an explanation of each type of solar eclipse:
A total solar eclipse is also known as a perfect solar eclipse. Occurs when the earth’s surface is covered by the moon’s umbra shadow.
This eclipse occurs only in the area affected by the umbra (core shadow) of the moon.
- Partial solar eclipse
A partial solar eclipse occurs when the Earth’s surface is covered by the Moon’s penumbra. There is still part of the sun visible.
It lasts longer than a total solar eclipse because the moon’s penumbral shadow is wider than the moon’s umbra.
An annular solar eclipse occurs when the moon is at its farthest point from the earth.
At this position, the length of the umbra cone does not cover the earth’s surface, but the extension of the moon’s umbra covers the earth.
Therefore, the sun will appear to shine in a ring-like shape.

Planet
A planet is a celestial body that revolves around the sun as its center with a fixed elliptical orbit.
The order of the planets from closest to the sun is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
Satellite
Satellites are objects that revolve around heavier objects. There are 2 types of satellites, namely:
- Natural satellites are satellites formed by nature, for example the moon is a satellite of the earth
- Artificial satellites are satellites made by humans such as communication satellites

Comet
Comets have another name, namely comets.
Comets are celestial bodies that revolve around the sun in an elliptical path and have heads and tails. When approaching the sun, the direction of the comet tail is always away from the sun.
In addition, comets are composed of rock mixed with metal, ice and frozen gas.
Examples of popular comet names are Halley, comet Kohoutek, comet Biella, and comet Encke.

Asteroid
Asteroids are celestial bodies like planets that are relatively small in size and circulate between the orbits of Mars and Jupiter.
Asteroid orbits are circular.
Examples of popular asteroid names are the asteroids Cerres, Pallus, Vespa, Apollo and Trojan.
Meteoroid
Meteoroids are solid objects that fly irregularly in space, originating from the fragments of asteroids, comets and other celestial bodies.
Meteoroids that are trapped into the Earth’s atmosphere and move at high speed toward the Earth’s surface are called meteors.
While meteors that can reach the earth’s surface are called meteorites.
