The largest planet

Our Solar system is one of the constituents of the Galaxy. Here the milky way extends for hundreds of thousands of light years. The Central element of the Solar system – the Sun. Around it revolve eight planets (the ninth planet Pluto was excluded from this list because he has the mass and gravitational forces are not allowed to be in the same row with the other planets). However, each planet is similar to the following. Among them are small and really huge, icy and fiery, which consists of gas and dense.

TrES-4

The largest planet in the Universe is TrES-4. It was discovered in 2006 and it is located in the constellation Hercules. The planet is called TrES-4 orbits the star, which is at a distance of about 1,400 light years from planet Earth.

The largest planet

The planet TrES-4 – ball, which consists mainly of hydrogen. Its size is 20 times the size of Earth. Researchers claim that the detected diameter of the planet by almost 2 times (actually 1.7) larger than the diameter of Jupiter (the largest planet of the Solar system). The temperature of TrES-4 of about 1260 degrees Celsius.

According to scientists, the planet has no solid surface. So it could be located. The mystery of how the density of matter that makes up this celestial body is so low.

Jupiter

The largest planet of the Solar system – Jupiter– is located at a distance of 778 million kilometers from the Sun. This planet, the fifth, is a gas giant. The composition is very similar to solar. At least in its atmosphere is mostly hydrogen.

The largest in the Solar system

However, under the surface of Jupiter is covered with ocean. It consists not only from water, and diluted under a high pressure of hydrogen boiling. Jupiter rotates very quickly, so quickly that extends along its equator. Therefore, there are formed an unusually strong wind. The look of the planet because of this particularly interesting: in the atmosphere clouds are extended and form a diverse and colorful ribbons. In the clouds there are vortices – atmospheric education. The huge already more than 300 years. Among them is the Great Red spot, which is many times larger than the Earth.

The elder brother of the Earth

It is worth noting that the planet’s Magnetic field is immense, it is 650 million kilometers. This is far bigger than the Jupiter. Field partially goes even beyond the orbit of the planet Saturn. Now Jupiter’s 28 moons. At least so openly. Looking at the sky from Earth, the farthest the moon looks smaller. But the largest satellite, Ganymede. However, especially scientists and astronomers are interested in Europe. It has a surface in the form of ice, also covered with strips cracks. Their origin is still a matter of much controversy. Some researchers believed that, under the balls of ice, where the water is not frozen, can be a primitive life. Far few places in the Solar system awarded such an assumption. In the future, scientists plan to send to the satellite of the Jupiter drilling rig. It is needed to study the composition of water.

Jupiter and its moons through a telescope

According to the modern version, the Sun and planets formed from a single dust cloud. Here the share of Jupiter had 2/3 of the total mass of the planets of the Solar system. And this is clearly not enough in the center of the planet was a nuclear fusion reaction. Jupiter has its own source of heat that is associated with the energy from compression and the decay of matter. If only heat was from the Sun, the top layer would have a temperature of about 100K. And judging by the measurements – it is $ 140K.

It should be noted that the atmosphere of Jupiter is 11% consists of helium, and 89% of hydrogen. This ratio makes it similar to the chemical composition of the Sun. The orange color is obtained with sulphur and phosphorus. For men they are harmful, because there is a poisonous acetylene and ammonia.

Saturn

This is the next largest planet in the Solar system. Through a telescope it is well visible that plusnet Saturn is stronger than Jupiter. The surface is parallel to the equator band, but they are less clear than the previous planet. Bars are shown in the numerous and dull details. And that is what the scientist William Herschel was able to determine the rotation period of the planet. It’s only 10 hours and 16 minutes. The diameter at the equator of Saturn slightly smaller than Jupiter. However by weight, it is second largest planet in three times. Besides, Saturn’s low average density of 0.7 grams per square centimeter. All because the giant planets are composed of helium and hydrogen. In the depths of Saturn’s pressure is not the same as on Jupiter. In this case, the surface temperature close to the temperature at which melts the methane.

Majestic Saturn

Saturn visible elongated dark bands or belts along the equator, as well as bright areas. These details are not as distinct as Jupiter. And individual spots are not as frequent. Saturn has rings. Visible in the telescope “ears” on both sides of the disk. Found that the rings of the planet are the remains of a huge near-clouds, stretching for millions of kilometers. Through the rings that rotate around the planet, can see the Stars. The inner parts rotate faster than outer.

Saturn in the telescope

Saturn has 22 satellites. They have names of ancient heroes, for example, Mimas, Enceladus, Pandora, Epimedii, Tethys, dione, Prometheus. The most interesting of them: Janus – he is the closest to the planet, Titan is the largest (greatest satellite in the Solar system in mass and size).

All the satellites of the planets, with the exception of Phoebe, turning in the forward direction. But Phoebe orbits in the opposite direction.

Uranium

Seventh planet from the Sun in the Solar system, so poorly lit. It is four times bigger than Earth in diameter. Some details on the Uranium, it is difficult to discern because of the small angular dimensions. Uranus rotates around the axis, lying on its side. Uranium passes in its orbit around the Sun in 84 years.

Mysterious Uranus

Polar day at the poles lasts 42 years, and then begins the night of the same duration. The composition of the planet – a small amount of methane and hydrogen. By circumstantial evidence is helium. The density of a planet larger than Jupiter and Saturn.
