What is the largest planet in the world?

In 2006, American astronomers discovered the largest and least dense planet discovered by 06. Its diameter is one-third larger than that of Jupiter, the largest in the solar system. It's so dense that some astronomers jokingly call it "like a big, loose cork" that can float on the surface of the water if it's big enough to hold it.

The least dense planet, called HAT-P-1, was discovered with the help of a network of small automated astronomical telescopes called HATs. The HAT-P-1 star is located about 450 light-years away from Earth and orbits a star in the constellation Scorpio. American astronomers thought it was an unusually strange planet, and they had never discovered such a strange object before.

Jaspar Bakos, one of the designers of the HAT Observatory, said: "Perhaps, we are discovering a new type of planet. ”

Hat-P-1 is twice the diameter of Jupiter, yet its density is only half that of Jupiter. If you can imagine putting Jupiter in a huge cosmic cup, it will sink, but this new planet, if you imagine putting it in the cosmic cup, it will float, and it will float very high, because it is only a quarter as dense as water. Equivalent to other planets, it resembles a large, loose cork.

Unlike Jupiter, Saturn, and other gas giants, HAT-P-1 does not have a solid nucleus. The star is very close to its "parent star", which is one-seventh the distance from Mercury to the Sun, so the planet has a very short orbital period, only about about a day. Scientists discovered the planet because when it flew by, it dimmed around the star it was flying on.

That star is one of a binary star system about 450 light-years from Earth. Although the properties of these two stars are very similar to those of the Sun, they formed about 900 million years later.

Jupiter is the largest in the solar system.

The largest planet that has been observed outside the solar system is "Tres-4", orbiting a star in space about 1,435 light-years away from Earth. The diameter is estimated to be times that of Jupiter.

No one knows about the largest planet in the universe.

The largest planet in the world is Jupiter.

Jupiter has the largest volume and mass among the eight planets in the solar system, and it has an extremely large mass, more than twice that of the other seven planets combined, 318 times that of Earth, and 1,321 times the volume of Earth. At the same time, Jupiter is also the fastest rotating planet in the solar system, so Jupiter is not positively spherical, but the poles are slightly flattened and the equator is slightly bulging.

Jupiter is the fourth brightest star in the sky, after the Sun, Moon, and Venus. Jupiter is mainly composed of hydrogen and helium, and its central temperature is estimated to be as high as 30,500. Jupiter has a large red spot on its surface, located south of Jupiter's equator.

From east to west, the longest is 48,000 kilometers, and the smallest is more than 20,000 kilometers; The longest from north to south is 14,000 kilometers, and the shortest time is 11,000 kilometers.

The internal structure of Jupiter:

Jupiter has a stony core composed of iron and silicon. Outwardly, it is composed of mixed particulate matter of rock and hydrogen, with no clear boundary, and is coated outwardly by a layer of liquid metallic hydrogen containing a small amount of helium, mainly hydrogen. On the inner core, most of the planetary material is concentrated, in the form of liquid hydrogen.

The most common form basis on these Jupiters may only exist at 4 billion Pa pressures, and it is this environment inside Jupiter that liquid metallic hydrogen is composed of ionized protons and electrons. Hydrogen is liquid rather than gaseous at the temperature pressure inside Jupiter, which makes it the electronic conductor and source of Jupiter's magnetic field, which is about 10 gauss, 10 times larger than Earth's.

1. The largest planet in the world is a nova named Xena;

2. Astronomers judge the size of the celestial body by the brightness of Zina, that is, how much sunlight it reflects, the brightness of the celestial body is not only related to the reflection area of the celestial body, but also affected by the surface of the planet, so before determining the real material of the wheel, scientists hypothesized different surface albedo models, and speculated on the size of the celestial body by calculating, and concluded that it is the largest planet in the world;

3. From the Earth, this nova is the third brightest star in the Kuiper Belt, and if it shines 100 percent of the rays, it has a diameter of 2,210 kilometers, and if the reflectivity is 90 percent, the diameter reaches 2,330 kilometers, which is about 2,400 kilometers in diameter.
