Which is the farthest planet in the world?

In the solar system, the farthest planet from Earth is Pluto. Among the celestial bodies that orbit the Sun directly, Pluto ranks 9th in volume and 10th in mass. Pluto is the largest outer Neptune object, second only to Eris in a discrete disk.

Like other Kuiper Belt objects, Pluto is composed mainly of rock and ice and has a relatively small mass, only 1 6 of the mass of the Moon and 1 3 of the Moon's volume. Pluto's orbital eccentricity and inclination are high, with a perihelion of 30 AU (4.4 billion km) and an aphelion of 49 AU (7.4 billion km).

Pluto periodically enters the inner side of Neptune's orbit, but does not collide due to its orbital resonance with Neptune. At average distance, it takes hours for the sun's rays to reach Pluto.

Pluto mass and size.

Pluto has a diameter of kilometers and a mass of (, which is the Earth's of the Moon. Its surface area is km2, which is about the same as that of Russia. It has a surface gravity of g (1 g for the Earth and g for the Moon).

Since Pluto is so faint and small, its size cannot be determined long after its discovery.

It was first estimated to be 6,600 km in diameter, but in 1949 it was changed to 10,000 km. In 1950, Gerard Kuiper revised its diameter to 6,000 kilometers with the newly built 5-meter telescope. In 1965, Gerard Kuiper used Pluto's occultation of a dark star to set the upper limit of the diameter at 5,500 kilometers.

In 1977, frozen methane was discovered on the surface of Pluto, and its albedo shrank to 2,700 kilometers in diameter.

It has been found that the Uy of the constellation Shield, located in the constellation Shield, is the largest known planet.

UY is a red supergiant. This star is the largest known star to date, surpassing the previously considered largest star in the constellation Canis Major.

The constellation Uy is about 9,500 light-years away, and its mass is not very large, only about 32 times the mass of the Sun, but it is very large, up to 2376511000 kilometers, or millions of kilometers.

Its size is so large that if the Shield constellation UY were placed in the center of the solar system, it would be larger in diameter than Jupiter's orbit (million kilometers) and close to Saturn's orbit (million kilometers). It takes more than 9 hours for light to orbit the star's equator, while light takes only seconds to orbit the Sun's equator. The star can hold about 4.5 billion suns, or about 200 million Earths.

Because in the known universe, the universe is constantly changing and expanding, and there are countless planets, so if you want to find the farthest planet in it, it is still not possible to use the current science and technology, but at present, human beings have found the galaxy farthest from the earth, named Abell1835 ir1916.

The farthest planet from Earth

Because galaxies are so far away from the Earth that there is no way to predict the planets that exist in them, and the universe is constantly changing and expanding, the farthest planet from the Earth cannot be found at present. Of course, in the solar system, the farthest star from Earth is the Sun, and the farthest planet from Earth is Uranus.
