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, similar in size to Makemake's moon MK2 but smaller, may have its rotation period and spin state investigated further through observations of Hiʻiaka. Once this is accomplished, it should be possible to better understand Namaka's influence on the 2009 data.
