"Pluto has suffered yet another blow to its status. Not only has it been demoted from planet to "dwarf planet", research now shows that it cannot even lay claim to being the biggest of these. A study has confirmed that the dwarf planet Eris - whose discovery prompted Pluto's relegation from planet to dwarf - outranks it in mass. The US team, whose work is published in the journal Science, described their finding as "Pluto's last stand"." |
