Namaka is similar in size to Makemake's moon MK2, despite being smaller. Further observations of Hiʻiaka might allow to determine its rotation period and spin state more precisely, at which point it should be possible to remove its effect from the data obtained in 2009.
Namaka, comparable in size to Makemake's moon MK2 despite being smaller, might have its rotation period and spin state determined through additional observations of Hiʻiaka. This could then allow for a better understanding of Namaka's impact on the 2009 data.
