25 000 light years from Earth discovered a huge planet eight times bigger than Jupiter
An international team of astronomers has discovered a world that is 2,500 times the size of Earth.
A planet called MOA-2011-BLG-322 about 8 times that of Jupiter, which is the largest planet in our solar system. Astronomers believe it orbits around a star, distant from us at a distance of 25 000 light-years and with a mass equal to a third of the Sun.

As reported by Ian O’neill in Discovery News, the giant planet was discovered using a technology known as “microlensing”.
Microlensing uses the General theory of relativity of albert Einstein, which assumes that gravity is actually the curvature of space and time. Continue reading
About the discovery of the ninth planet of the Solar system two astronomers from the California Institute of technology in Pasadena became known on January 20. One of them — the native of Russia Konstantin Batygin — spoke about the search for Planet X, the difficulties with the title the new heavenly bodies and unsolved mysteries of the Solar system.
What is an open planet?
Konstantin Batygin . She falls into the category of dwarf planets. This celestial body is quite massive. Our model gives a mass of about ten earth, this planet is just a giant. Now it is defined as a celestial object whose gravitational field is dominant in that part of the Solar system.
In General, there is not even a question: it’s a planet or not. We know about it, because its gravity affects the orbit of the farthest objects in the Kuiper belt. The very mathematical modeling relies on the fact that this planet has enough mass for gravity to dominate in the Solar system. Continue reading
Our universe is huge, and it seems to us that more of the globe there can be nothing, but it is not. There are planets much larger and more massive. For the whole of the Universe our Earth is just a grain of sand lost in her. 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. And only ninth – Pluto – due to its gravitational forces and the mass deduced from the list of rotating planets. Each planet has its own parameters, density, temperature. There are those that are composed of gas, there are giant, small, hot, cold, dwarf.
So what is the biggest planet known at the moment? In the spring of 2006 an event occurred that shook the theory about the heavenly bodies. In Rovellasca Observatory (USA, Arizona) in the constellation of Hercules was discovered a huge planet beyond our Earth twenty times. Existing outdoor today it is the largest planet in the Universe. She’s hot and like the Sun, but it’s still a planet. It was called TrES–4. Continue reading
