How many planets in the solar system
The number of planets of the solar system
The current number of planets in the solar system is 8 planets، and it is mentioned that there are 5 planets described as dwarf، which are:
Ceres، Pluto، Haumea، Makemake، and Eris، and it is noteworthy that the number of planets in the solar system was 9 planets، between 1930-2006 AD.
The number of planets was 8 before the year 1930 AD، and it is the same that is approved at the present time. This is due to the discovery of Pluto in 1930 AD، when it was added to the solar system، then removed from the elements of the main group and joined to another group.
The following is a mention of the eight planets of the solar system:
- Mercury: Mercury does not have an atmosphere، it is gray and rocky، and it contains many craters.
- Venus: Its temperature is 480 degrees Celsius، and it is called the morning or evening star.
- Earth: The only planet in the solar system that contains water on its surface، as water covers three quarters of the Earth's surface.
- Mars: Mars has the largest volcano compared to the rest of the planets in the solar system، which is Olympus Mons، as it is called the Red Planet.
- Jupiter: The largest planet of the solar system، and there is a large red spot on its surface، which is a huge storm that occurred more than 300 years ago.
- Saturn: Saturn is surrounded by clear rings، which are bits of ice and rock that orbit it. Uranus: Its color is bluish-green due to the methane gas in its atmosphere.
- Neptune: The winds on Neptune are the fastest in the solar system، with a speed of about 2000 km/h.
- The reason for the exclusion of Pluto from the planets of the solar system
- The International Astronomical Union (IAU) made a decision to exclude Pluto from the planets of the solar system in 2006 AD and consider it a dwarf planet. This is because not all of the terms used in the International Astronomical Union apply to it.
