A planet in a four-star system

...But it's not a planet anymore. So we're still unique!

Pluto is SO a planet!

Isn't Pluto smaller than our own moon?

No. Planetoid. It fails to meet the criteria of having sufficient gravity to pull itself into a sphere. If Pluto got to stay in the planet club, then loads of planetoids since discovered, would have more of a claim than Pluto to planetary status, so they drew a line in the sand and made sure Pluto was on the wrong side of it...

Gustav Holst knew what he was doing - when they eventually commissioned a Pluto addition to the Planets Suite, it just didn't fit, musically.

I may be all of 22 years old, but when it comes to Pluto, I'm still old-fashioned.

He's not the best of Disney's creations if I'm honest.

Hanna-Barbera however recognized Bluto as a great character.

(My initial thought was to invoke  Godwin's Law when I saw Disney, but then I realised that would just be a cheap joke. )

Which brings to mind Wimpy - I could murder a cheese-burger, at the moment!

And if you could just lend me a dollar, I will gladly repay you Tuesday.

<chortles> As it happens, I possess an old one-dollar bill that I've had for decades - I'll 'port it to you! <feeds note into the optical drive>

Sure it's not over 9000?

May I point out to any noobs here that this isn't likely to be an Oolite feature for quite some time!

Sorry, wrong DH. It's a "Dwarf Planet" and it is large enough to pull it into a sphere. The criteria it fails to be a full blown planet is "(c) has cleared the neighbourhood around its orbit" as there are a lot more object in similar orbits nearby.

Full definition:

Code: Select all

A planet is a celestial body that 
    (a) is in orbit around the Sun, 
    (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and 
    (c) has cleared the neighbourhood around its orbit 

The definition of the Dwarf Planet is:

Code: Select all

A celestial body that 
    (a) is in orbit around the Sun, 
    (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, 
    (c) has not cleared the neighbourhood around its orbit, and 
    (d) is not a satellite.

... has [not] cleared the neighbourhood around its orbit" as there are a lot more object in similar orbits nearby.

This may well prove a problem for the New Horizons probe, which is on its way there.
