Astronomers have discovered a planet outside our solar system that is 12 times the size of Jupiter, striking not only for its size but also for the fact that it is not orbiting any star.
The so-called “rogue” planet does not revolve around a star, but instead rotates around the galactic center in interstellar space.
Astronomers say there have been only a few rogue planets discovered to date. They say even though finding such celestial objects are rare, there could be large amounts of such planets in the universe that have yet to be discovered.
The recently discovered planetary mass was originally found in 2016 but was mistaken for a brown dwarf planet. According to new research published in the Astrophysical Journal, the object is now thought to be a planet in its own right, with an usually strong magnetic field.
Astronomers say the magnetic field of the new planet, named SIMP J01365663+0933473, is more than 200 times stronger than Jupiter’s. They say its strong magnetic field likely led to its being detected by a large radio-telescope in New Mexico known as the National Science Foundation’s Karl G. Jansky Very Large Array (VLA).
The planet is thought to be 200 million years old and is 20 light-years from Earth. (VOA)
