Sedna's relatively high visible-wavelength geometric albedo of 0.32 (which suggests a NIR geometric albedo close to or exceeding 1.0) indicates an ice-rich surface, despite the clear spectral signatures of complex organic molecules.
...As estimated in (Trujillo et al., 2005, Barucci et al., 2005, Emery et al., 2007, Pál et al., 2012, Trujillo and Sheppard, 2014), the object has a layer of hydrocarbon sediment produced by irradiated methane. The existence of the hydrocarbon sediment may be a reason why the Sedna's surface is a bright red shade (Cuk, 2004, Sheppard, 2010)....
Spectra of all three objects show steep red spectral slopes and strong, broad absorptions between 2.7 and 3.6 μm indicative of complex organic molecules......These differences of Sedna, Gonggong, and Quaoar from the smaller KBO population supports the inference of different evolutionary history based on their size.

We examined the past history of the three most detached trans-Neptunian objects (TNOs)—Sedna, 2012 VP113, and Leleakuhonua (2015 TG387)—the three clearest members of the dynamical class known as sednoids, with high perihelia distances q...
The discoverers (Brown et al., 2004) have supposed that Sedna was created in the Solar System at the early stage of its evolution, and its orbit was changed because of dynamic effects that followed the Sun's formation within a dense stellar cluster (Brown et al., 2004, Morbidelli and Levison, 2004, Kenyon and Bromley, 2004, Adams, 2010, Kaib et al., 2011, Brasser and Schwamb, 2015). According to other versions, Sedna's orbit was changed by a stellar encounter (Kaib and Quinn, 2008) (e.g., the passing Scholz's star about 70 thousand years ago (Mamajek et al., 2015) at a distance of 52 thousand au from the Sun), or Sedna was captured from a low-mass star or a brown dwarf in interstellar space (Morbidelli and Levison, 2004).
ABSTRACT Recent analyses have shown that distant orbits within the scattered disk population of the Kuiper Belt exhibit an unexpected clustering in their respective arguments of perihelion....In this work we show that the orbits of distant Kuiper Belt objects (KBOs) cluster not only in argument of perihelion, but also in physical space. We demonstrate that the perihelion positions and orbital planes of the objects are tightly confined and that such a clustering has only a probability of 0.007% to be due to chance....can be maintained by a distant eccentric planet with mass 10 m⊕ .... whose perihelion is 180° away from the perihelia of the minor bodies....Continued analysis ....provides the opportunity for testing our hypothesis as well as further constraining the orbital elements and mass of the distant planet.

the census of dwarf planet satellites shows all the biggest systems seem to have satellites. Sedna isn't known to, but any satellite would spend at least a quarter of its time lost in Sedna's glare [...] no additional satellites for Makemake, Eris and OR10 down to 26th mag. Haumea has already been checked. Sedna the last remaining to double-check!
