THE SOLAR SYSTEM

 Hello viewers, today we shall learn about the solar system.

THE SOLAR SYSTEM

The sun together with the group of celestial bodies that are held by its attraction and revolve around it The term Solar System refers to the "family" of the Sun. The Sun is a star around which eight planets, among other celestial objects, revolve in orbits. This whole system of bodies is called the Solar System. Or it is a collection of eight planets and their moons in orbit around the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets. The planets of the solar system are (in order of distance from the sun) Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids. 

There are eight planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. ... Our solar system is an orderly arrangement of planets orbiting the Sun. Pluto, a dwarf planet, was classified as one of the solar system planets when it was first discovered by Clyde Tombaugh. According to the IAU, Pluto is technically a “dwarf planet,” because it has not “cleared its neighboring region of other objects.” This means that Pluto still has lots of asteroids and other space rocks along its flight path, rather than having absorbed them over time, like the larger planets, have done the 14 Planet Theory was a theory by the ArcHivist Farazea, which was supported and cited by ArcHivist Hegelia in her CyberHive. It was through this theory that Farazea explained that Sol's solar system originally contained fourteen planets, up to Planet 14, whilst 20th century Earth humans believed there to be only nine. 

By the order of the 14 Planet Theory, the planet was Mercury and Moon, Venus, Mondas, Earth, Mars, Asteris, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon, and many other Planets Noting the similarities in composition and size between Mercury and what would become Earth's Moon, Farazea suggested that the future moon, the fourteenth planet in the solar system by what might have been ancient Mondasian reckoning, originally formed as a twin planet to Mercury before being dislodged from its orbit, sending it on a course which led it to close in on the twin planets of Mondas, Planet 4 in the ancient cosmology, and Earth, Planet 5. This resulted in Mercury's twin being caught in Earth's gravity and becoming its moon, whilst Mondas was displaced from its orbit and fell on a course to the edge of the solar system.

The solar system's asteroid belt was thought by many cosmologists and corroborated by evidence in Image of the Fendahl to be the remains of an ancient planet, which Farazea referred to it as Asteris. Just prior to the return of Mondas in the 20th century, Earth cosmologists were engaged in an observation of the skies to find Planet 10, not Mondas, but a body beyond Pluto in order to explain the perturbed orbits of the outer planets. Pluto's own moon, Charon, which observed by the ArcHivists to be so relatively large that together they might have been described as double planets. By 20th century Earth assumptions, the solar system could be said to have contained, with Mondas, Asteris, and Planet 10, twelve planets. Including the cometary cloud, the solar system extended to a distance of about 1 and a half light-years or 40 billion miles from Sol. As Pluto was just over 3 and a half billion miles from Sol, the expanse which remained under the solar influence could be said to have contained at least one more substantial body that may have been called a planet, Planet 14.

A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.

Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.

How Big Are Black Holes?

Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "stuff," in an object.

Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the sun. There may be many, many stellar mass black holes in Earth's galaxy. Earth's galaxy is called the Milky Way.

The largest black holes are called "supermassive." These black holes have masses that are more than 1 million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths.

How Do Black Holes Form?

Scientists think the smallest black holes formed when the universe began.

Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space.

Scientists think supermassive black holes were made at the same time as the galaxy they are in.

If Black Holes Are "Black," How Do Scientists Know They Are There?

A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting, a black hole.

When a black hole and a star are close together, high-energy light is made. This kind of light can not be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.

Could a Black Hole Destroy Earth?

Black holes do not go around in space eating stars, moons and planets. Earth will not fall into a black hole because no black hole is close enough to the solar system for Earth to do that.

Even if a black hole the same mass as the sun were to take the place of the sun, Earth still would not fall in. The black hole would have the same gravity as the sun. Earth and the other planets would orbit the black hole as they orbit the sun now.

The sun will never turn into a black hole. The sun is not a big enough star to make a black hole.

A black hole is one prediction of Einstein's theory of general relativity. Another is known as a white hole, which is like a black hole in reverse: Whereas nothing can escape from a black hole's event horizon, nothing can enter a white hole's event horizon.
