Haumea on January 21, 2017, as seen from Earth. On this date, Ortiz et al. (2017) reported observations from multiple Earth-based observatories of Haumea passing in front of a distant star (a multi-chord stellar occultation). These observations allowed them to constrain the shape of Haumea’s projected ellipse on the sky. The pink lines represent the projected occultation chords derived from the reported timings, while the yellow endpoints indicate the associated uncertainties in the ingress and egress times. The facet colors on the projected body indicate the relative level of irradiance received by each facet, with red corresponding to lower incidence angles and therefore higher irradiation. The overall agreement between the projected shape and the occultation chords supports the validity of our simulation.
