It is thought that the [original Haumea] (large object in the center of the figure) was a differentiated or partly-differentiated object with a rocky interior and an icy/rocky mantle. Most of the icy/rocky mantle has been removed, and the fragments ejected created the Haumea family members (grey objects). [What's left over] is the current Haumea. Several objects are classified as candidates to the family (red objects). They are not official members of the family because their composition is unknown or because they have no ice on their surface as the other members of the family. Shape of these objects is approximate and has been derived from their light curves. In some cases, objects have never been observed for light curves and so we do not have a good constrain about their shape. These objects are indicated with a question mark.

The Moon is waning this week, heading toward new Moon on Friday. This means that at the beginning of the week it will be visible just before dawn in the southeastern sky as a slim crescent, on Sunday night as a slim crescent in the southwest just after sunset. What it also means is that the Moon is "out of the way" for observing the stars and other faint objects in the sky, a prime time for deep sky observers. Just after sunset, look for Saturn very low in the southwest. The slim crescent Moon will be 1° north of it on Sunday evening. Also at nightfall, look for Mars shining brightly in the south. Just before sunrise in the southeastern sky, Venus is remarkably bright - about as bright as it ever gets. Mercury is also becoming visible by week's end, about 25° to the lower left of Venus.
