90377 Sedna
90377  (symbolum: ), olim designatione 2003 VB12 agnitus, est asteroides systematis solaris nostri, corporibus transneptunianis attributus. Astronomis terrestribus magnitudinem absolutam  monstrat. Die   a Michaele E. Brown, Chad Trujillo, et Davide L. Rabinowitz in Observatorio Palomar versatis repertus est. 

Rerum orbitalium ratio epochae  constitit. Qua epocha 90377  per dies  circa solem movebatur. Axem orbitalem habebat unitatum astronomicarum  et eccentricitatem , distans igitur a sole quam minime unitatibus , quam maxime unitatibus . Inclinatio orbitalis ° reperiebatur, anomalia media °.
