    So, Dawn is going to land and take a Ceres of photographs…
    (ducking now)

    Did they upgrade Ceres to a dwarf planet … just so they could say we’re finally landing on a dwarf planet instead of an asteroid?

    According to Google, Ceres was discovered 129 years before Pluto.

    True.

    But Pluto is only held to be a dwarf planet by the PC crowd. Unfortunately, the other four planets discovered have been all but ignored by the public because of the rather stupid-sounding monikers “trans-neptunian object” and "dwarf planet. Such names are strongly suggestive of campy 1950s science fiction like Plan 9 From Outer Space.

    It says something that scientists would ignore physics and fluid mechanics to claim that ceres might have liquid water. Subsurface or not, given what has happened in te rest of the solar system, the temperatures would be too cold and there too little gravity to hang onto it. As ceres cooled, cracks would open up (just like other planetary bodies) and water would escape. The best that could be hoped for would be small remnants like on the Moon and Mercury.

    If Ceres is so much smaller than the Moon, and is a dwarf planet, does that mean the Moon is a planet? I’m so confused….

    Within the category of Dwarf Planet Ceres fits and it is larger than Pluto.

    Yet again the tired whipping boy “PC” is nonsensically dragged into it. How does it have any bearing on anything?

    Luna is a moon. Maybe you should look up the size parameters of what constitutes a Dwarf Planet.

    According to the definition created by the International Astronomical Union in 2006, a planet:
    “1) is in orbit around the Sun,
    2) has sufficient mass to assume hydrostatic equilibrium (a nearly round shape), and
    3) has “cleared the neighbourhood” around its orbit."

    This means that the Moon is not a planet because it fails part 1 of the definition (it orbits the Earth, not the sun). Asteroids fail part 2, because they’re not massive enough to become spherical under their own weight. Pluto and Ceres fail part 3 because they haven’t cleared out the space around their own orbits (that is, they haven’t absorbed the rest of the belt that they belong to).

    In order to identify Pluto as being different from a regular asteroid, the IAU created the class of “dwarf planets” in 2006 as:
    “1) is in direct orbit of the Sun
    2) is massive enough for its shape to be in hydrostatic equilibrium under its own gravity
    3) has NOT cleared the neighborhood around its orbit.”

    (Again, part 1 eliminates our Moon as a dwarf planet.) The IAU announced 5 recognized dwarfs in 2008: Ceres, Pluto, Haumea, Makemake, and Eris. There are believed to be at least 100 other dwarfs in the asteroid belt, but they have not yet received official recognition as such.

    The rationale behind removing Pluto from the list of planets is that if you only need to satisfy the first two conditions (orbit the sun, and is roughly spherical), then you need to add Ceres to the list of “real planets” because it’s bigger than Pluto, and that opens the gates to the 100 other “dwarfs” that are roughly the same size as Pluto.

    If Pluto is not a dwarf planet, does that mean we have to change its name to Sneezy. Bashful or Doc?

    I think this is one Ceres that will never get cancelled! (now
    I will duck!)
