Why is the Sun a Star Is the Sun a star or a planet

The mass of the sun is large enough to allow hydrogen atoms to fuse and release energy continuously and steadily, so it is called a star.

Why is a TV a TV, why is a mobile phone a mobile phone, what is the problem, first of all, stars must be made of hot gases, globular objects that are also capable of emitting their own light, all it is, understand?

Stars are spherical or spheroid-like objects made up of hot gas that emit light on their own.

There is no definitive answer to this, this is a term formulated by scientists, but a star is a star that emits high heat and its body is covered in fire.

Because the sun relies on its massive mass for nuclear fusion, producing light and heat.

Celestial bodies made up of hot gases that emit light on their own are called stars such as the sun and stars, and the sun is the closest star to the earth

Well! Good question. Jupiter wouldn't be the first planet without fusion!

If you want to go, if you can't think of it, you'll die.

The planets orbiting it are moving, so it is relatively constant.

In terms of stars and planets, the Sun belongs to the category of stars because the gravitational pull inside the Sun is sufficient to condense hydrogen matter, and the mass is high enough to ignite the hydrogen matter to convert energy and make itself shine. Planets can't live up to that. But in the vast galaxy, the Sun is only a medium-sized star.

The Sun is a star.

In terms of the definition of a star, the Sun is certainly able to meet the definition of a star as a planet. The gravitational pull inside the Sun is strong enough to condense the hydrogen material, and the mass is so massive that it ignites the hydrogen material to convert the energy and make itself shine, and from this point alone, the Sun can be used as a star.

In the solar system, the eight planets are all under the gravitational pull of the sun, following the sun to make an orbit. The Sun is the only star in the solar system, and the other stars are either planets or moons, or other dwarf planets. Their volume and mass are not comparable to that of the sun.

The hydrogen contained in the sun is constantly undergoing thermonuclear reactions, so that the sun can always emit light and heat, and its surface temperature is almost 6000, not to mention the internal temperature will be even higher. In the solar system, the Sun is already considered a large star, but in the Milky Way, the Sun is just an ordinary medium star.

The Sun is a star. The closest star to Earth is the Sun. Older stars like the Sun rotate at a lower rate and have milder surface activity.

The Sun is the most typical star of the Milky Way, about 25,000 to 28,000 light-years from the center of the galaxy. The solar system moves at a speed of about 220 kilometers per second and makes one revolution in the galaxy for 22,600 years. The nine planets in the solar system all orbit in a near-circular orbit in about the same plane, orbiting the Sun in the same direction.

With the exception of Venus, the other planets have the same direction of rotation and revolution.

The Sun is the largest object in the solar system. It has the mass of the entire solar system. The sun is personified in many myths: the ancient Greeks called it helios, while the ancient Romans called it sol.

The Sun Sol is a G-type main-sequence star about 100 million kilometers away from us, which belongs to the star and is also a proper noun. It has a diameter of about 1.39 million kilometers and a power of watts, and the energy of one second is enough for one person and one heavy truck (more than 14 tons) in the world to circle the equator about 100,000 times, or hundreds of thousands of years in the world.

Stars are a universal concept that includes the Sun and at least a few trillion other stars in the observable universe, as well as historical and future stars, that emit light by their own nuclear reactions (black dwarfs and black holes, etc.). The above is not a definition). In contrast to planets, ancient people lived on the surface of the earth, did not have telescopes, and observed that most of the stars that were basically immobile during a person's life were stars, and it was the planets that were obviously moving.

Now we know that the position of stars in the sky is not fixed either.

The Sun is a true subset of stars, the closest star to us, and at the same time occupies the mass of the solar system, and the mechanism of its fusion reaction is not fully understood by humans, which is also one of the biggest mysteries of the solar system.

The Sun is a star.

The Sun is just a very ordinary star in the universe, but it is the central object of the solar system. In the solar system, eight planets, including our Earth, some dwarf planets, comets and countless other small bodies of the solar system orbit the sun under the strong gravitational pull of the sun.

The gravitational pull inside the sun condenses the hydrogen mass, and the mass reaches the point where it ignites the hydrogen matter to convert the energy and make itself shine, almost an ideal sphere intertwined with a hot plasma and a magnetic field. There are 50 closest star systems at a distance of 17 light-years from Earth, and the closest star to the Sun is a red dwarf called Proxima Centauri, about light-years.

Introduction to Planets.

Planets, usually referring to celestial bodies that do not emit light on their own and orbit a star, get their name from the fact that their positions are not fixed in the sky, as if they were walking, and their orbit is often in the same direction as the rotation of the star they orbit. Generally speaking, planets need to have a certain mass, and the mass of the planet must be large enough to be as similar to spherical as it is, and it cannot undergo nuclear fusion reactions like stars.

Historically, planets got their names from the fact that their positions were not fixed in the sky, as if they were walking in the stars. The five planets visible in the solar system, namely Mercury, Venus, Mars, Jupiter and Saturn, have been discovered by humans as early as prehistory.

The Sun is a star.

The Sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way. The Sun is a star located at the center of the solar system, and it is almost an ideal sphere intertwined with hot plasma and magnetic fields.

The diameter of the Sun is about 1,392,000 (kilometers, which is 109 times the diameter of the Earth. It is about 1.3 million times the size of the Earth, and its mass is about 2,100 kilograms (330,000 times that of the Earth). In terms of chemical composition, about three-quarters of the mass of the Sun is now hydrogen, and almost all of the rest is helium, including oxygen, carbon, neon, iron, and other heavy elements with less than 2% of the mass, which uses nuclear fusion to release light and heat into space.

Introduction to the heliosphere

The heliosphere, which extends from about 20 solar radii (astronomical units) to the edge of the solar system, is a large area of space that surrounds the sun filled with plasma that accompanies the solar wind as it leaves the sun. Its inner boundary is where the solar wind becomes the super-Alfen wave – the fluid is faster than the Alfen wave, because the message can only be transmitted at the speed of the Alfen wave, so the turbulent and dynamic forces outside this boundary can no longer affect the shape of the inner corona.

The solar wind enters the heliosphere and blows outward, causing the Sun's magnetic field to form a spiral shape until it hits the sheath more than 50 AU from the Sun. In December 2004, the Voyager 1 probe had crossed the shock front, which is believed to be part of the solar sheath, and both Voyager spacecraft detected and recorded energetic particles with more energy than ordinary particles as they crossed the boundary.

Other stars can be seen at night on Earth, but they are so far away that they look like they are just fixed spots of light.
