2018 VG18

Is NOT a dwarf planet. It is a possible dwarf planet CANDIDATE.

It is NOT the farthest known object in the solar system. 90377 Sedna goes out much, much further as do most of the non-periodic comets.

It is the farthest object OBSERVED in the Solar System. Both Sedna and Dwarf Planet Eris were closer to the sun in their long, elliptical orbits when they were discovered. That is key here. Farthest observed.

How can I be so sure about these things. Very simple. I wrote THE BOOK on Dwarf Planets!

We had another FALSE Dwarf Planet claim in 2016. Click image to access that post.


So this is exciting, but we have to keep it in perspective.

It has now been over 10-years — YES, 10-years — since we have had a NEW dwarf planet. There is politics here and possibly even some second-thoughts and regrets, Maybe they were hasty in coming up with the classification ‘dwarf planet’. Minor planet and trans-Neptunian object (TNO) might have sufficed.

But, I will keep you posted.

See 2nd line of table.

Pluto, 11-years ago was the FIRST solar system object to be designated a Dwarf Planet!

Pretty special.


Our latest view of Pluto is NEAR real color — from 2015.

Eris was discovered on January 5, 2005 from images taken October 21, 2003.

July 29, 2005 was the ANNOUNCE day — when dwarf planet Makemake was also unveiled.

Eris is a remarkable solar system object with an amazingly long and distant orbital path. At its furthest it is over 97 TIMES further from the Sun than Earth. It takes Eris 558 years to make one orbit of the Sun!

CNN & Others WRONG. There Is NO New Dwarf Planet, viz. 2015 RR245.

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?
