The planet HD 106906 b is a typical rogue planet. It is a huge wooden planet, and its volume is 1 1 times that of Jupiter. However, its distance from its parent star is 650 times that of the sun and the earth. This unusual discovery, scientists predict that it will probably be abandoned and become a rogue planets. Because the star HD 106906 is very young and in the forming stage, many planets will be expelled and become rogue planets during this period.
20 1 1 year, research teams from New Zealand and Japan wrote in the famous scientific magazine Nature that they found ten Jupiter-sized planets drifting in the universe. At that time, scientists thought that there were 200 billion rogue planets in the Milky Way, twice the number of stars in the Milky Way. Sumi, a scientist at that time, said, "Just as people predicted their existence, the discovery of free-running planets is not surprising, but it is really surprising that they are so common."
In the new study of 20 17, American scientists believe that there are fewer rogue planets in the Milky Way than expected, unlike the study of 20 1 1 which has 200 billion. According to new research, there are only 654.38+000 billion rogue planets in the Milky Way. But it can still prove that rogue planets are everywhere in the galaxy, and the number far exceeds that of planets accompanying stars like the earth.
