Our universe is huge, and it seems that more of the world there can be nothing, but it is not.There are planets much larger and heavier.For the entire universe, our earth - just a grain of sand lost in it.The solar system is only one element of the Galaxy.The sun - is the main component of the galaxy.Eight planets revolve around the sun.It was only the ninth - Pluto - because of its gravitational forces and the mass deduced from the list of planets rotating.Each planet its parameters, density and temperature.There are those that consist of gas, there is a giant, small, cold, hot, dwarf.
So what's the largest planet known so far?In spring 2006, an event that shook the theory of celestial bodies.The Lowell Observatory (USA, Arizona) in the constellation of Hercules was discovered a huge planet, exceeds the size of our Earth twenty times.Of the existing open today - is the largest planet in the universe.She is red-hot and is similar to the sun, but it is still a planet.She called TrES-4.Its size exceeds the size of the largest planet in the solar system - Jupiter - 1.7 times.It is a giant ball of gas.TrES-4 is composed mainly of hydrogen.The biggest planet revolves around the star, which is located at a distance of 1400 light years.Temperature conditions on its surface is over 1260 degrees.
There is a sufficient number of giant planets, but so far not opened more than TrES-4b.The biggest planet Jupiter size exceeds more than 70%.A huge gas giant could be called a star, but its rotation around its star GSC02620-00648 it definitely relates to planetary celestial bodies.As reported by the responsible officer of the observatory G. Mandushev, gaseous planet greater than the firm, and it is possible unless dive.Its density ranges from 0.2 grams per cubic centimeter, which is comparable only with balsa (cork) tree.Scientists astronomers speculated how this largest planet with such a low density has the ability to exist.Planet TrES-4 is also called TrES-4b.His discovery, it is obliged to amateur astronomers that discovered TrES-4 through a network of small automated telescopes in the Canary Islands, located in the state of Arizona.
If you observe this planet from the ground, then it is clear that it is moving across the disk of its star.Attention extrasolar planet around the star in just 3.55 days.Planet TrES-4, compared with the Sun harder and has a higher temperature.
pioneers were employees of Lowell, and later astronomers Harvard University and the Hawaiian observatory WMKeck confirmed this discovery.At Lowell Observatory scientists have suggested that the largest planet TrES-4 - not only in this constellation, and it is quite possible in the constellation Hercules may be another planet.Employees Lowell in 1930 opened the world's smallest planet in the solar system - Pluto.However, in 2006, Pluto, compared with the giant TrES-4, began to be called a dwarf planet.
