Galaxy and planet concept
The solar system belongs to the Milky Way galaxy, the galaxy is a large gathering of stars, planets, and moons, in addition to dust and gases, and all these components are linked with each other by gravity, and galaxies are divided into types that differ according to the shape into three types, as follows:
- Elliptic shape: They are the elliptical, disk-shaped galaxies that do not have a specific axis of rotation.
- Spiral shape: They are galaxies with three components: the center, the disk, and the halo.
- Irregular shape: These galaxies are characterized by not having a regular shape, and they are galaxies that contain a lot of dust in them, which prevents starlight from spreading.
As for the planet, according to the International Astronomical Union, it is a body orbiting the sun, and it has sufficient mass to have its own gravity in order to make its orbit around the sun, and it also has a number of small bodies that revolve around its orbit.
The solar system is a system in space that consists of a gathering of a central star, which is the sun and around which the various bodies revolve, namely: the eight planets, and its moons, which number about 170, and countless numbers of asteroids and some of its moons, in addition to comets, gases and dust , And icy bodies, and the solar system includes the eight planets arranged in ascending order according to distance from the sun, as follows:
The solar system belongs to the Milky Way
The solar system belongs to the Milky Way galaxy, also called the Milky Way galaxy, which is a spiral galaxy, which is one of the most famous galaxies as it includes the sun, the earth, and the rest of the planets of the solar system, so that it includes hundreds of billions of stars, and this galaxy consists of Huge clouds of dust and gas atoms in all parts of the galaxy, and contain nearly 400 billion stars, and the Milky Way appears in the form of a broad beam of starlight extending across the sky, and can be seen from the surface of the planet on dark, clear nights.
The solar system belongs to the Milky Way galaxy and the globe belongs to the solar system, and the planet is the third in terms of distance from the sun, and this is what makes it a planet where the temperature remains within the moderate range, and this is what allows water to exist in its liquid state on the surface of the earth, as well as The Earth is surrounded by the atmosphere, which is a source of oxygen gas, and thus it is the only planet currently known to have life in it, and the Earth is the largest of the four rocky planets in the solar system.
The solar system belongs to the Milky Way galaxy and space is made up of many galaxies such as the Andromeda galaxy that was first observed by the astronomer Abdul Rahman bin Omar Al-Sufi, which can be seen with the naked eye without using the telescope, and it is about 2.5 million light years away from us, and the Magellan Cloud consisting of two galaxies Two irregular dwarfs.
