Most distant object in our solar system spotted. But it’s not Planet Nine.
There’s a dwarf planet in our solar system, far beyond the orbit of Pluto, that swings so far away from the sun that from its perspective Earth and Saturn look like neighbors. Source: https://www.livescience.com/farfarout-planet-distance-record.html

Is Planet Nine a Black Hole?
“Astrophysicists have recently begun hatching plans to find out just how weird Planet Nine might be,” reports the New York Times. Long-time Slashdot reader fahrbot-bot shares their report:
Although it is probably wishful thinking, some astronomers contend that a black hole may be lurking in the outer reaches of our solar system. All summer, they have been arguing over how to find…
Solar system may have had a second sun that helped grab Planet Nine
In its youth our solar system may have contained two suns, which could explain how it had the gravitational pull to capture the hypothetical Planet Nine Source: https://www.newscientist.com/article/2252719-solar-system-may-have-had-a-second-sun-that-helped-grab-planet-nine/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
The sun may have started its life with a binary companion
A new theory published today in the Astrophysical Journal Letters by scientists from Harvard University suggests that the sun may once have had a binary companion of similar mass. If confirmed, the presence of an early stellar companion increases the likelihood that the Oort cloud was formed as observed and that Planet Nine was captured rather than formed within the solar…
