Orbit Diagram
Note: Make sure you have Java enabled on your browser to see the applet. This applet is provided as a 3D orbit visualization tool. The applet was implemented using 2-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances. For accurate long-term ephemerides, please instead use our Horizons system.

Note: If the applet has stopped working because of a recent Java upgrade, here is a possible workaround.
Orbit Viewer

Additional Notes: the orbits shown in the applet are color coded. The planets are white lines, and the asteroid/comet is a blue line. The bright white line indicates the portion of the orbit that is above the ecliptic plane, and the darker portion is below the ecliptic plane. Likewise for the asteroid/comet orbit, the light blue indicates the portion above the ecliptic plane, and the dark blue the portion below the ecliptic plane.

Orbit Viewer applet originally written and kindly provided by Osamu Ajiki (AstroArts), and further modified by Ron Baalke (JPL).

136108 Haumea           Discovered 2003 Mar. 7 at the Sierra Nevada Observatory.
Haumea is the goddess of childbirth and fertility in Hawaiian mythology. Her many children sprang from different parts of her body. She takes many different forms and has experienced many different rebirths. As the goddess of the earth, she represents the element of stone. The satellites (136108) Haumea I and II were discovered by M. E. Brown, A. H. Bouchez and the Keck Observatory Adaptive Optics teams. Haumea I, discovered 2005 Jan. 26, is named Hi'iaka, who was born from the mouth of Haumea and carried by her sister Pele in egg form from their distant home to Hawaii. Hi'iaka danced the first Hula on the shores of Puna and is the patron goddess of the island of Hawaii and of hula dancers. Haumea II, discovered 2005 Nov. 7, is named Namaka, for a water spirit in Hawaiian mythology. Namaka was born from the body of Haumea and is the sister of Pele. When Pele sends her burning lava into the sea, Namaka cools the lava to become new land.
