Interview with Mike Brown on his hunt for planet nine.

Quote
Still, not everyone is confident that Planet 9 will be found any time soon—or at all. A new study from a team of scientists at Queen’s University in Belfast asserts that the discovery of a minor planet called 2013 SY99—which is, at its closest, 50 AU—might dash our hopes of ever discovering the world. After running computer models of the solar system, the researchers concluded that if Planet 9 did exist, it likely would have altered SY99's orbit so much we would not be able to view it.

“Computer models do show that a Planet Nine would be an unfriendly neighbor to tiny worlds like SY99: its gravitational influence would starkly change its orbit – throwing it from the solar system entirely, or poking it into an orbit so highly inclined and distant that we wouldn’t be able to see it,” Michele Bannister, an author on the study, wrote in The Conversation. “SY99 would have to be one of an utterly vast throng of small worlds, continuously being sucked in and cast out by the planet.”

Bannister told Gizmodo that while her team’s findings don’t entirely disprove the idea of Planet 9, it calls the hypothetical world’s legitimacy into question.

“The planet 9 idea is a fun idea, it’s exciting, but it’s taking a bit of the oxygen at the moment,” she told Gizmodo. “We have this interesting problem…and the very shiny solution at the moment is called planet 9.”

Brown, on the other hand, read Bannister’s paper and said he and Batgyin had predicted that astronomers would discover objects just like SY99. He said that finding these objects actually reinforces the idea that Planet 9 is out there.

“The reason that we initially thought Planet 9 existed—there are a lot more reasons now—but the initial reasons were that the most distant Kuiper Belt objects were on these very eccentric orbits that are all pointing off in the same direction,” he told Gizmodo. “One of the things we said when we first announced this a year ago was that, ‘We predict that as you continue to find more and more distant Kuiper Belt objects, they too will be pushed off in this one direction. So we’ve been waiting for all these discoveries to come in—this one is exactly where it’s predicted.”

Scientists need your help to find the mysterious planet they suspect is lurking in our solar system

Have they considered walking backwards slowly? That always works in horror movies  :)

Why the clustering of distant eccentric KBOs is not an observational bias (I'll show you Thursday!)

Hubble spots moon around third largest dwarf planet

Quote
The combined power of three space observatories, including NASA’s Hubble Space Telescope, has helped astronomers uncover a moon orbiting the third largest dwarf planet, catalogued as 2007 OR10. The pair resides in the frigid outskirts of our solar system called the Kuiper Belt, a realm of icy debris left over from our solar system’s formation 4.6 billion years ago.
