Astronomers discover very distant object orbiting the Sun
Astronomers have discovered a very distant object in a solar orbit ranging from 6 billion to 213 billion miles from the Sun.
Designated 2015 TG387 and nicknamed “The Goblin” by its discoverers, this object resides in the inner Oort Cloud, a region beyond the Kuiper Belt that until now harbored only two other known bodies: the dwarf planet Sedna and the less well-known 2012 VP113.
The scientists estimate its size to be about 200 miles in diameter. Based on the existence of the three known objects in this region of space, the scientists estimate there could be as many as 2 million objects there bigger than 25 miles in diameter. There is a lot of uncertainty in that number.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

It would be nice if one of the decadal science surveys prioritized a mass survey of the asteroid belt and/or oort cloud. With launch prices coming down and innovative satellite designs, it might be possible to mass produce and launch enough probes to make a serious effort at mapping the asteroid belt and oort cloud.
It isn’t as flashy as a trip to Europa but in the long term is probably much more beneficial.
Good idea wodun! I would expect several more Plutantoids being discovered also.
Bob,
Is this the title you intended? Distance vs. distant
I read a story in Analog years ago that posited planetoids in a 70,000 yr orbit between Sol and the Centauri system, which at least sounds plausible. But I suspect relative motion would disrupt any such orbit. It does seem interstellar space may not be as empty as believed.
Chris: Thank you. Post is fixed.
