Astronomers have discovered one of the youngest and brightest planet known to us. Freely moving object marked as 2MASS J1119-1137 goes alone through space. Mass between 4 to 8 masses of Jupiter floating without orbit since 10 million years.
Freely moving planets are similar to planets that travel alone through space. Object-J1119 has been sighted 1137 2MASS thanks to the Wide-field Infrared Survey Explorer (WISE) and with some ground orbit on past. The researchers turned their attention to him, because it emits much more infrared radiation against we expected in our theoretical assumptions.
Analyzes the 2MASS J1119-1137 by FLAMINGOS spectrograph-2, placed on the 8-metre Gemini South telescope in Chile. It was confirmed that in this case we are dealing with a planetary mass, in a small neighborhood of the Sun, which is not a star.
Astronomers linked object 2MASS J1119-1137 with a young group of more than 20 stars that are moving in one direction of WT Hydrae. Their age is determined as 10 million years old. Managed to also specify the distance from the Lonely Planet it’s “only” 95 light years.
Astronomical observation results are carefully published in The Astrophysical Journal Letters.
