List of Dwarf Planet Candidates - Probable Per Brown

Probable Per Brown

Mike Brown considers the following bodies, ranked by estimated size, to be "probably" plutoids. Asteroids are not considered.

The terms for varying degrees of likelihood are:

Near certainty: Sufficient confidence to say these must be in hydrostatic equilibrium even if predominantly rocky.
Highly likely: Estimated/measured to be over 600 km. The size would have to be "grossly in error" or they would have to be primarily rocky to not be dwarf planets.
Likely: Estimated/measured to be over 500 km. Uncertainties in measurement mean that some of these will be significantly smaller and thus doubtful.
Probable: Estimated/measured to be over 400 km. Expected to be dwarf planets if they are icy and that figure is correct.

Famous quotes containing the words brown and/or probable:

    She does not know
    Her beauty,
    She thinks her brown body
    Has no glory.
    Waring Cuney (1906–1976)

    It was only too probable that among the half-converted Pagans and Jews, any rite, any form, would find favor, whilst yet unable to comprehend the spiritual character of Christianity.
    Ralph Waldo Emerson (1803–1882)
