A Kuiper belt object turns out to be large
New observations of Kuiper Belt object 2007 OR10 have found it to be the largest unnamed object in the solar system, 955 miles across and about two-thirds the diameter of Pluto.
It also appears to rotate slowly, with each day about 45 hours long.
These results are decidedly uncertain, so don’t put much money on them. Nonetheless, the data continues to suggest that there are a lot of objects out there beyond Pluto.
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
