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.
Sedna is not expected to support an atmosphere at its great distances
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
The community typically refers to these objects as "dwarf planets," though the IAU acknowledges only four TNOs officially as such: Pluto, Eris, Makemake, and Haumea.

...No moon has been detected around Sedna, so it is not yet possible to calculate its density

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!
