Sedna is asteroid #90377 and listed as an anomaly. Sedna is way further out than the suspected outer end of the Kuiper Belt, but still much closer to the Kuiper Belt than to the suspected Oort Cloud. Sedna can be categorized as a Distant Detached Object, but these are actually empty words because Distant Objects are all asteroids, that are further out than Jupiter, so that even if Saturn should ever catch a trojan, then this would already be a Distant Object; and Sedna is a Detached Object because she isn’t in resonance with a planet because she is too far away from any planet. Hence it probably makes sense to give her the own category of sednoids and see whether more sednoids can be found.

Sedna’s orbit shows an inclination of 11.9° with respect to the ecliptic. Sedna’s orbital period is 10513 years with an uncertainty of plusminus twenty years. An orbit counts only as confirmed, when a whole orbital period was observed! So we’ll have to wait for about eleven-thousand years until all the main information about Sedna can be confirmed! The perihelion of Sedna is about ten and a half hours of light away from the Sun and the aphelion of Sedna is about five days of light plus five hours of light away from the Sun. This means that Sedna’s orbit exhibits a very high eccentricity. Sedna’s initial designation is 2003 VB12. Sedna rotates in ten hours around herself, but also eighteen hours were measured and initially a rotation period of forty days, which is regarded as inexplicably slow for an object of Sedna’s size. Sedna is only a tad bigger than Ceres.

Sedna is named after the sea goddess of the Inuit. Her tale as many variations. I can well imagine how longer stories were told at the fires in longer nights. Sedna begins as a kind of princess, the daughter of a rich man, of the best hunter, or of a chieftain. For an unusually long time in respect to the culture of the Inuit, does she enjoy the luxury of her father’s home. Nowhere else among the Inuit could she have lived in such luxury, hence she doesn’t want to leave, no matter how many men want to marry her. But then she is either forced by her father to marry or abducted by a stranger or seduced by a stranger to go with him and live with him in a far away kingdom. Sedna leaves her home with the hope to live in an environment with even more luxury. Depending on the version of the tale, her father follows her and wants to rescue her because she was abducted, or her father regrets his decision and goes on an adventurous search for the far away kingdom, or Sedna realizes that she was tricked and her husband isn’t rich and Sedna flees and tries to go back to her father’s home. In the longer versions has Sedna to marry many husbands and to go through all of these adventures. The different versions align when Sedna sits in the boat of her father and a powerful magical creature, who is either her husband or a servant of her even more powerful husband, chases the two. The magical creature can fly and is much faster than the boat. So Sedna and her father can’t escape. Either because of a sense of honor of his family or because of a huge fear in respect to the magical creature decides Sedna’s father to sacrifice Sedna and throws her overboard. Sedna tries to climb back into the boat, but her father draws his knife and cuts her fingers off. Sedna falls into the sea and sinks down to the ground. Some other magical creatures or deities watched how Sedna was sacrificed by her own father and felt pity for her. So they decided that Sedna should no longer be human, made her immortal and Sedna became the goddess of the sea. Her cut off fingers turned into fishes. Sedna realized that there was a famine among her Inuit tribe. In some versions of the tale this was also the reason why her father felt an urgent need to let her marry into another tribe. Sedna felt pity for her people and created all forms of sea life and also the amphibian life (not like batrachians, but like seals) in order to feed the Inuit. Hence Sedna could be count into the deities of creation and frugality, but her tale offers more than the usual tales of creation deities.

I should link you to a certain website, where the astrological relevance of Sedna was examined, but I won’t find it again. It had anyway only two cases, which is much too few to judge any relevance. But they were very impressive cases, where people lost a hand or a foot like Sedna lost her fingers. Sedna is an Arctic goddess, hence from an area, where you would always be in a real danger to lose fingers or toes because of the coldness. More people lose their toes there than their fingers. If you did ever see a real frostbite, then you know for sure that coldness is a very serious danger. Arctic deities could indicate consequences of coldness. This should be examined for Sila-Nunam too. Otherwise can’t be said much about Sedna with respect to the many uncertainties, which still prevail in the understanding of our Solar System as well as ourselves.
