Summary[edit]

Description
Català: Aquests quatre panells mostren la ubicació de l'objecte transneptunià (90377) Sedna, que es troba en els confins del sistema solar.[1] ada panell, movent-se en sentit horari des de la part superior esquerra, successivament s'allunya per col·locar Sedna en el seu context.

El primer panell mostra les òrbites dels planetess interiors i Júpiter; i el cinturó d'asteroides.

En el segon panell, Sedna es mostra també fora de les òrbites de Neptú i els objectes del Cinturó de Kuiper.

L'òrbita completa de Sedna s'il·lustra en el tercer panell, juntament amb la ubicació de l'objecte en l'any 2004, arribant al seu màxim acostament al Sol.

L'últim panell s'allunya molt més, que mostra que fins i tot aquesta gran òrbita el·líptica que rau dins del que es creu que és la vora interior del núvol d'Oort esfèric: una distribució de cossos gelats i freds situats en els límits de l'atracció gravitacional del Sol. La presència de Sedna suggereix que el disc intern prèviament especulat sobre l'eclíptica sí que existeix.
English: These four panels show the location of trans-Neptunian object 90377 Sedna, which lies in the farthest reaches of the Solar system.[2] Each panel, moving clockwise from the upper left, successively zooms out to place Sedna in context.

The first panel shows the orbits of the inner planets and Jupiter; and the asteroid belt.

In the second panel, Sedna is shown well outside the orbits of Neptune and the Kuiper belt objects.

Sedna's full orbit is illustrated in the third panel along with the object's location in 2004, nearing its closest approach to the Sun.

The final panel zooms out much farther, showing that even this large elliptical orbit falls inside what was previously thought to be the inner edge of the spherical Oort cloud: a distribution of cold, icy bodies lying at the limits of the Sun's gravitational pull. Sedna's presence suggests that the previously speculated inner disk on the ecliptic does exist.
