Is Planet 9 A Black Hole, Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs)—bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth, over 250 astronomical units (AU). Is Planet 9 a black hole? A group of astronomers, including The subject of much speculation, most theories suggest that Planet Nine is a previously undetected planet, but it may also flag the existence While investigating other gravitational sources of what may be messing with TNOs (no matter how improbable they are) is good science, it's more likely that Planet However, there is one almost outrageously peculiar scenario in which the planet will never be found this way – it might not be a planet after all, but a black hole. If we were to discover a lurking black hole, rather than a frigid planet, Unwin says there would be no need to panic. We take these objects to be primordial black holes (PBHs) and point out the orbits of TNOs would be altered if one of these PBHs was captured by the Solar System, inline with the A comet-eating black hole the size of a planet? It's possible. Cambridge, MA - Scientists at Harvard University and the Black Hole Initiative (BHI) have developed a new method to find black holes in the An artist’s concept of Planet Nine, a yet-unobserved object thought to orbit 20 billion miles from the sun. "There's a supermassive black hole in the centre of our galaxy," he The primordial black hole could be playing the gravitational role of “ Planet Nine ”, which is a hypothetical world that could explain the Could ‘Planet 9’ actually be an ancient black hole? A new paper suggests a primordial black hole may be making things weird at the edge of our Is there a “Planet Nine” lurking at the fringes of the solar system? Or could it be something a whole lot more scary—a primordial black Explore the evidence suggesting Planet Nine is either a massive, icy world or an Earth-mass primordial black hole. As the search for Planet Nine wears on, and astronomers have yet to get so much as a glimpse of it, researchers are pondering what else the object might be. These ETNOs tend to make their closest approaches to the Sun in one sector Explore the evidence suggesting Planet Nine is either a massive, icy world or an Earth-mass primordial black hole. Scientists have chased a theory for decadesbut is it a ghost, a black hole, or a newfound planet? A ‘ghost planet’ sounds like something . For nearly 5 years, growing numbers of scientists have blamed the weird orbits of distant solar system objects on the gravitational effects of an Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. And if there's one out there in the distant Solar System, a pair of researchers A recently published paper suggests that it is possible that planet 9 is actually a tiny black hole. Now, Harvard scientists have proposed a way to determine, once and for all, whether Planet Nine actually could be a black hole. Is “Planet 9” actually a primordial black hole? Astronomers think there’s another planet in our solar system, but no one has been able to see it. Instead, it could be an ancient primordial black hole that could fit inside the A new theory suggests that Planet 9 may not be a planet after all, but a primordial black hole left over from the Big Bang that created the If Planet 9 is a black hole (and that's a big "if" indeed), within a few years we could launch a mission to observe it in detail, and hopefully answer some long-burning questions in physics. But a radical new theory suggests it may not be a planet after all. Specifically, the new method would scour the Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. Two physicists now think it's possible It sounds like a crazy idea, but it isn't outside the realm of possibility. Some astronomers have Space Astronomy Black Holes Is Our Solar System's Mysterious 'Planet 9' Really a Grapefruit-Size Black Hole? It probably isn't a black hole, if it For nearly 5 years, growing numbers of scientists have blamed the weird orbits of distant solar system objects on the gravitational effects of an An artistic rendering of Planet Nine, a hypothetical massive object that orbits the sun beyond Neptune. To begin with, if Planet Nine is a planet-mass black hole, its gravitational pull on TNOs would be exactly the same.
