A dwarf planet is a planetar-mass object that is neither a planet nor a naitural satellite. That is, it is in direct orbit o the Sun, an is massive enough for its gravity tae crush itsel intae a hydrostatic equilibrium shape (uisually a spheroid), but haes nae cleared the neighbourhuid o ither material aroond its orbit.[1][2]
