Almost Two Years Later, We Still Don't Know if Planet Nine Exists
Almost Ii Years Later, Nosotros Still Don't Know if Planet Nine Exists
Our solar system used to have nine planets before the demotion of Pluto to "dwarf planet," but some scientists recollect there might still be nine planets. Perhaps we but haven't been able to spot the 9th planet because it'south so afar. Information technology's been nearly two years since researchers from Caltech hypothesized that highly unusual orbits of objects in the Kuiper Chugalug pointed to an undiscovered massive object. No ane has been able to disprove the idea still, simply the scientific community is even so skeptical.
The planet nine hypothesis was put forrard by Caltech astronomers Konstantin Batygin and Mike Brown. According to Brown, he expected other researchers to disprove the thought rather rapidly, merely no one has done so however. He says this has turned him into something of a "true believer" in planet 9.
The paper suggesting planet nine was based on a mathematical analysis of Kuiper Belt Objects (KBOs) and their orbits. The Kuiper Belt is a ring of icy bodies out past the orbit of Neptune. It turns out Pluto was but the first KBO ever spotted past astronomers. Batygin and Brownish contended a planet approximately 10 times the mass of Globe would explain an unusual alignment of KBOs they had detected in the outer solar organization. More recently, the duo has pointed to other objects in the outer solar organization that have been tweaked out of alignment as evidence.
On the other side of the argument are scientists unconvinced by the undiscovered planet explanation. Astronomers from the Outer Solar Arrangement Origins Survey claim Batygin and Dark-brown are beingness misled past factors like poor weather and the location of the telescope. When you have a fuller picture of the Kuiper Chugalug, there may exist nothing special virtually the arrangement of these KBOs. If the alignments are only random, there'due south no testify for planet ix.
Planet nine (in orange) could account for all the purple orbits.
Still others believe the scientific customs is overlooking the true culprit: the Kuiper Belt itself. Ann-Marie Madigan from the University of Colorado Boulder explains that there could be many more KBOs out there than anyone expected, so it'southward wrong to ignore their potential gravitational impacts as near assessments accept. If there are billions of small planetoids in the belt, it'southward possible they're responsible for the unusual orbits cited by Batygin and Brown.
Science tin can be a bit unsatisfying at times like this when we don't yet know the truth. However, that's the merely right respond right now. Some astronomers believe nosotros'll have enough information in the next 1 or 2 years to either confirm or refute planet nine. Until then, the speculation will go along.
