Although the centaurs share a reddish or neutral coloration with many SDOs, their nuclei are bluer, indicating a fundamental chemical or physical difference.Following the discovery of the planet Neptune in 1846, there was considerable speculation that another planet might exist beyond its orbit. 1) Classification: Sedna is a Trans-Neptunian Object (TNO), which just means that it is an object out past Neptune. Its discoverer Michael E. Brown has suggested instead that it should be considered an inner Oort-cloud object rather than a member of the scattered disc, because, with a perihelion distance of 76 AU, it is too remote to be affected by the gravitational attraction of the outer planets. The Oort cloud lies beyond the scattered disc. Sedna is well beyond the Kuiper Belt which lies at roughly 30-55 AU. Although the centaurs share a reddish or neutral coloration with many SDOs, their nuclei are bluer, indicating a fundamental chemical or physical difference.Rodney S. Gomes, Julio A. Fernandez, Tabare Gallardo, Adrian Brunini (2008). The Minor Planets Center lists Sedna as an SDO (Scattered Disc Object).

The scattered disc (or scattered disk) is a distant region of the Solar System that is sparsely populated by icy minor planets known as scattered disc objects (SDOs), a subset of the broader family of trans-Neptunian objects (TNOs). Modern theories indicate that neither Scattered objects, like other trans-Neptunian objects, have low densities and are composed largely of frozen Astronomers originally supposed that the trans-Neptunian population would show a similar red surface colour, as they were believed to have originated in the same region and subjected to the same physical processes.One explanation is the exposure of whiter subsurface layers by impacts; another is that the scattered objects' greater distance from the Sun creates a composition gradient, analogous to the composition gradient of the terrestrial and gas giant planets.The Kuiper belt was initially believed to be the source of the Solar System's ecliptic comets.

Over time, the scattered disc would gradually form from these isolated events.Computer simulations have also suggested a more rapid and earlier formation for the scattered disc.
