how many plants are there in the solar system? Always keep this question in mind, and while the answer to this question is supposed to be easy, it is not accurate for everyone. Especially after discovering that none of these planets have the characteristics of a planet, so you can downgrade it to a dwarf planet. What is this planet? How is the planet in the solar system? This is what we will learn about on the occasion of the meadow in our article above.
What is the solar system?
The solar system is about 4.6 billion years old, and our solar system consists of the sun, the planets that revolve around it, dozens of moons, and millions of asteroids, comets and meteorites due to gravity. Located in the Milky Way, there are tens of billions of other solar systems in the universe in the Milky Way, and some of these systems contain more than one star.
how many plants are there in the solar system?
The number of planets in the solar system is eight, after excluding Pluto and considering it a dwarf planet, because it does not possess the characteristics and properties of other planets. These planets are: Mercury, Venus, Earth, Mercury, Jupiter, Saturn, Uranus, and Neptune.
What is the solar system?
The solar system is divided into three types:
planets
The planet is a celestial body in its orbit. It has gravity resulting from having mass, and gravity is responsible for creating equilibrium, which forms planets into spherical or elliptical shapes. Its gravity is responsible for expelling nearby objects from the planet’s orbit. These planets are:
- Mercury: Mercury is the closest planet of the solar system to the sun, and it is also smaller and slightly larger than Earth. It revolves around the sun in only 88 days. Because of its close proximity to the sun (about five times the distance between Earth and the sun), Mercury experiences dramatic temperature changes between night and day. Daytime temperatures reach 840°F (450°C), hot enough to melt lead. Meanwhile, on the night side, temperatures drop to minus 290 degrees Fahrenheit (minus 180 degrees Celsius).
- Al-Zahraa: Al-Zahraa is the second planet in distance from the sun, and Venus is the second planet in size. Under the radar the atmosphere varies, the surface of mountains and volcanoes. He is also the son of Mercury. The average temperature on the surface of Venus is 900 degrees Fahrenheit (465 degrees Celsius). Surprisingly, Venus moves slowly from east to west, which is the opposite direction for most other planets.
- Earth: the third planet in the sun’s dimension, two-thirds of the Earth is covered by oceans. It is the only planet known to have life. The planet orbits the sun at more than 18 miles per second (29 km per second).
- Mars: The fourth planet after the sun, a cold desert-like place covered with rain. This dust is composed of iron oxides that give the planet its distinctive red colour. Mars is similar to Earth in terms of terrain, and there are mountains, valleys, valleys, and storm systems ranging from hurricane-like dust devils to dust storms sweeping across the planet.
- Jupiter: The fifth planet in distance, the largest planet in our solar system, more than twice the mass of all the other planets combined, according to NASA. The vortex cloud also mixes different types of rare gases.
- Saturn: The sixth planet from the sun, and it is famous for its rings made of ice and rocks, and scientists were not sure how they were formed.
- Uranus: The seventh planet from the Sun, Uranus is the planet of moods. It contains clouds of hydrogen sulfide, the same chemical that makes rotten eggs smell so bad. It goes from east to west like the sun. But unlike Venus or any other planet
- Neptune: The eighth planet of the sun, Neptune is the size of the planet Uranus, and is known for the fastest winds. Neptune is far from Earth. The planet is thirty times farther from the sun than Earth. Neptune was the first planet to be predicted using mathematics, before it was discovered visually.
dwarf planets
Celestial bodies revolve around the sun. Its gravity and mass are responsible for the formation of spherical or elliptical shapes.
Small solar system objects
Minor solar system objects are all objects in the solar system except planets and dwarf planets. It includes all comets, meteorites, most asteroids, near-Earth objects, and objects beyond Neptune. Examples of minor solar system bodies and their definitions:
- Asteroids: They are small bodies in the solar system ranging in size from planets to meteorites. The difference between them and comets is that when comets approach the sun, they emit tails, but nothing comes out of comets.
- Comets: These small bodies from the solar system give off tails as they approach the sun.
- Meteorites: They are small bodies in the solar system, which are solid bodies larger than atoms and smaller than asteroids.
Conditions for the validity of the Kcap orb
In 2006, the International Astronomical Union (IAU) changed the terms and conditions used to classify a celestial body as a satellite. Thus, you change the list of planets and consider that a celestial body that does not meet the conditions is a planet. And we draw up a new list of the names of the planets that meet the conditions, and these conditions are:
- All celestial bodies revolve around the sun.
- The object must be large and have a reliable gravity that is responsible for giving it a spherical shape.
- Also, the orbit should be cleaned.
- It prevents other celestial bodies from entering the special orbit.
Why did you exclude Pluto from the solar system?
If the criteria of the blue planet do not match the criteria of other planets, you are excluded for many reasons from the solar system, among them:
- The small size does not give enough gravity to dominate the environment, or the path to orbit is somewhat disordered.
- The orbit that Pluto travels is different from other planets, so all the planets in the solar system revolve around the sun in a relatively flat plane, but Pluto revolves around the sun at an angle of 17 degrees.
- From this plane in addition, the orbit is exceptionally elliptical and intersects the orbit of Neptune.
- Scientists have also discovered that Pluto is one of the many bodies orbiting the sun in a region of the solar system called the Kuiper belt, and scientists believe that there are many icy and rocky bodies in this crowded region that are as large or larger. from Pluto. To admit thousands of crimes as whole planets too.
How many planets in the universe?
After knowing the number of planets in our solar system and that it consists of eight planets, then the question arises about the number of planets in the universe? Even today, scientists have no idea about the total number of these planets. And we still don’t have the technology to monitor anything outside the door. We live in just one of thousands of star systems in our galaxy, the Milky Way. The universe is also believed to contain trillions of galaxies.
After answering the question, how many planets are in the solar system? We touched on the number of planets in the solar system according to their proximity to the sun, and we talked briefly about the characteristics of each planet, and we have finished our article for today.
