Another view of 2015 RR245’s amazingly distant orbit around the Sun from my favorite JPL orbit tracker. You can see Pluto, Neptune, Uranus etc. — as dots — for reference. Click to ENLARGE. Copy and paste this link “http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2015%20RR245;old=0;orb=1;cov=0;log=0;cad=0#orb” into FireFox (not Chrome). Does not work with Chrome!


2015 RR245 (which known as a temporary designation (and indicates WHEN in 2015 it was discovered)) is indeed small, i.e., less than 1/3rd the size of Pluto, and amazingly far away. BUT that does NOT automatically make it into a Dwarf Planet.

CoverJPGI do know a fair amount about Dwarf Planets. I have written a book about them.

As of today, July 13, 2016, there are but five (5), and only five (5), dwarf planets. They are: Ceres, Pluto, Haumea, Makemake and Eris. Period. Full stop. Just 5. Ceres, Pluto, Haumea, Makemake and Eris.

CNN cannot designate a Solar System body a Dwarf Planet.

Neither can any astronomer.

For that matter neither can NASA or its European equivalent, ESA!

That a Solar System body is a Dwarf Planet can ONLY be designated by the International Astronomical Union (IAU). That is it.

Until the IAU says it is a Dwarf it is NOT a dwarf. Simple as that.

The last time the IAU designated a Solar System body a Dwarf was on September 17, 2008. See below. That was Haumea. They have kept their ‘powder dry’ since then!

So nobody but nobody can jump the gun.

Until the IAU says so, 2015 RR245 is NOT a Dwarf Planet.

Got that?

It is a Main-Belt Asteroid and as such is always outside the orbit of Mars.

The 342843 is a sequence number, in that it is the 342,843rd confirmed ‘Minor Planet’ to have been discovered, Ceres (now a Dwarf Planet) having the honor of being the 1st, i.e., 1 Ceres. Pluto now that it is a dwarf is numbered 134340.

The name is optional and is initially put forward by the discoverer of the asteroid.

As of today 701,660 ‘Minor Planets’ have been catalogued as having been discovered. 19,712 of them, just a mere 2%, are named. Here is the list. So to have an asteroid named after you is, of course, special, BUT not that exclusive.

The ‘Beatles’ collectively and individually have asteroids named after them, viz. 8749 Beatles, 4147 Lennon, 4148 McCartney, 4149 Harrison & 4150 Starr. Some of the others include Carlos Santana, Frank Zappa, Eric Clapton, Jerry Garcia, Jimi Hendrix, Led Zeppelin, Mike Oldfield, Miles Davis, Frank Sinatra, Bee Gees, Buddy Holly etc. etc. Here is a list.

So David, as is due, has been honored as a ‘spaceman’.

Robert Irion’s July 2013 Article In ‘National Geographic’ Rather Lax With The Facts!

I am, and have been for decades, a great fan of ‘National Geographic’. It is one of the few magazines that we continue to subscribe and do so without fail.

I dived into the July 2013 cover story about the ‘Solar System’ as this is very germane to the work I have been doing on 4 Vesta and Comet ISON (C/2012 S1).

There is at least one huge howler that tungsten and titanium nitride could only have been created by the Sun. WRONG.

So, for the first time in my life I wrote a letter to the Nat. G. Editors.
