In addition to the sun and the earth, the solar system also has various other celestial bodies
The solar system is a collection of celestial bodies that are arranged with the sun as the center of its cycle. In one orbit around the galaxy, the solar system takes about 230 years.
The composition of the solar system does not only consist of the sun, but also other space objects.
The gathered celestial bodies consist of a star called the sun and other objects that are attracted by its gravity called the solar system. The largest members of the solar system are the planets. Each planet has its own characteristics and satellites.
The following have Popmama.com summarize information about the various celestial bodies in the solar system that you need to know. Let’s see!
1. Asteroid
sciencetimes.com—
Asteroids are celestial bodies that are chunks of rock and metal scraps with uneven surfaces and varying sizes. Asteroids are composed of dust and ice, making asteroids very hard objects and dangerous if they hit the earth.
Some of the asteroids are between the planets Mars and Jupiter, which are clustered together to form a belt-like collection that orbits the sun.
The path of an asteroid orbiting the sun is oval or elliptical. This collection of belts is home to hundreds of thousands of asteroids of varying sizes, from as small as a particle of cosmic dust to as large as a miniature planet.
Usually, this collection of belts is referred to as the Asteroid Belt. Although the asteroid moves freely around the sun, this one celestial body is not as active as a meteor.

2. Galaxy

A galaxy is a massive, gravitationally bound system consisting of stars, the cosmic gas and dust of the interstellar medium, and an important component known as dark matter.
There are many galaxies with different shapes, but the most common is the Milky Way Galaxy. Because, Earth is in the Milky Way Galaxy. The Milky Way galaxy is a large spiral-shaped galaxy, in which there is the solar system, in which the planets revolve around the sun.
The Milky Way Galaxy is close to the Andromeda Galaxy, so sometimes they are close to each other or even bump into each other.

3. Comet

Comets are celestial bodies that resemble stars. For this reason, comets are often referred to as tail stars. Even so, this assumption is not correct because the comment is not a star that can emit its own light. This means that comets cannot emit light or light.
Comets revolve around the sun in very oval or elliptical orbits. However, most comets have a parabolic orbit.
Comets are made up of gas, ice and dust. When the comet moves closer to the sun, the ice sheet on the comet will evaporate which is then a collection of vapor and dust pushed by the solar wind away from the sun.
As it approaches the sun, the comet’s tail is behind. Meanwhile, when a comet moves away from the sun, its tail is in front. Comet tails have different shapes and sizes can reach millions of kilometers.
The closer a comet is to the sun, the longer its tail will be. Even so, there are also comets that do not have tails.

Other celestial bodies in space are meteors, meteorites, and meteoroids. Often, meteors are also referred to as meteorites and meteoroids. In fact, meteors, meteorites, and meteoroids have differences.
Meteoroids are pieces of rock or metal debris containing iron and metal elements that move through space. Meteoroids revolve around the sun in a definite orbit and their speed varies with a maximum speed of about 42 km per second.
Meteors are objects that glow as they pass through the earth that move very quickly. Meteors are often referred to as shooting stars or switching stars.
Meanwhile, meteorites are meteors that do not burn out and can reach the earth’s surface. Meteorites are what create large holes in the earth’s surface.

5. Nebula

Clouds found in outer space are called nebulae. This nebula is an interstellar cloud consisting of dust, gas, and plasma. The size of the nebula is very massive and can accommodate many planets or stars. Therefore, the carapace nebula is often referred to as the birthplace of stars and galaxies.
The most commonly known nebulae are the Omega Nebula and the Helical Nebula. While the largest nebula is the Tarantula Nebula. The nebula is located in our galaxy and stretches over 1,800 light -years to 170,000 light -years from Earth.

6. Planet

Planets are the most celestial bodies known to humans. The planet orbits the sun and has a mass large enough for the force of gravity and has cleared the environment around its orbit.
Reported from solarsystem.nasa.gov, celestial bodies in the solar system must have three criteria in order to be called a planet, namely as follows.
- Planets must orbit a star
- Planets have to be big enough to have gravity to form their own spheres
- The planet must be large enough, so that its gravity washes away all the other objects around it
In this world, there are eight planets commonly known to humans, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

7. Satellite
en.wikipedia.org—
A satellite is a celestial body that does not have its own light source and orbits a particular planet by following its orbit or orbit. Earth’s natural satellite is the moon because the moon orbits around the earth.
Satellites are divided into two types, namely natural satellites and artificial satellites. Natural satellites are satellites that already exist in the solar system, such as the moon.
While artificial satellites are satellites that are intentionally made by humans that are launched using rockets, for example the Palapa Satellite belonging to Indonesia. The artificial satellite is intended for mapping, communication, weather monitoring, and so on.
Well, that’s the kinds of celestial bodies in the solar system that you need to know. Hopefully this information can add to your insight!
