The biggest planet in the Universe

The solar system in which we live is only a small part of our galaxy, and the galaxy itself is a small element of the infinite Universe. Man is not fully understood and even its own system, and adjacent areas of space. Especially since a lot of «white spots» in the constellations, from which we are separated by light years. The scale of the Universe is so large that the study of man is currently available only the biggest planet.

Giant in the constellation of Hercules

But how large are they? You can answer the question of which planet is the biggest? Scientists from Arizona (Rovellasca lab) believe so.


In 2006, in the constellation of Hercules, they discovered the planet, whose dimensions exceed the dimensions of the Earth 20 times. The planet was given the name of TrES–4. This molten giant is like a star, but a planet. TrES–4 is more of Jupiter (the largest planet in the Solar system) in 1.7 times. According to currently available data, it is the biggest planet in the Universe.


Hydrogen planet

Despite its Titanic size, TrES–4 is inferior to the Jupiter mass. The reason is that the planet is composed of rarefied gases, mainly hydrogen. To land on it, it is impossible. If it reached the spaceship, he would literally immersed inside the planet. The density of its substance is only 0.33 g/CC Therefore, the radius RJ 1,706 mass of the planet is just 0,917 MJ. Scientists generally surprised that at such a low density planet keeps its shape, do not spray in space.


The low density of TrES–4 due to the proximity of the star, which kindles the substance of the planet. The components of the gas temperature reaches 1260 degrees Celsius (2300 degrees Fahrenheit). Proximity to the star (4.5 million km) and speed in orbit also explain the surprisingly short year TrES–4. The largest planet in space makes a full revolution around its star in just 3.5 days.


The low density of the planet gives rise to low gravity. As a result, and as a result of heating by the star, the planet may not securely hold own stuff. It is constantly enveloped in a gas-dust cloud. TrES–4 is expanding, losing part of the atmosphere. As a result, the planet a noticeable «tail», such as those that distinguish comets.


At the time of discovery of TrES–4 was the largest exoplanets known to humanity, but still found it recently. It proves that hiding the depths of space has many mysteries. Adventurers are constantly faced with new challenges, and not all have managed to find a solution.
