摘要

The orbits of the moons of the dwarf planet Haumea.

Note the unusual inclination and high eccentricity of the orbit of the inner moon.

Graph

• Orbits
  • Hi'iaka in blue
  • Namaka in green

• The orbit Namaka is plotted in a brighter colour above the plane of the orbit of Hi'iaka and in a darker colour below.
• Major axis drawn showing perihelia (q) and aphelia (Q) with the dates of the passage.
• Bodies
  • Relative sizes (not to scale with the orbits) are illustrated
  • The bodies' positions as of: JD 2454615.0 (the epoch from the Brown's paper; 2008-05-15)
• Orientation
  • Haumea in the centre.
  • The view is from above the orbit of Hi'iaka (~ 30 degrees above, longitude ~300 degrees)
