Vue d'artiste comparant la taille de fr:90377 Sedna avec d'autres objets du fr:Système solaire comme la fr:Terre, la fr:Lune, Pluton et fr:50000 Quaoar dont on pensait, jusqu'à présent (2004-mar-15) qu'il était le plus grand corps céleste après Pluton. Le diamètre de Sedna est légèrement inférieur à celui de Pluton mais supérieur à celui de Quaoar.

description originale

The artist's rendition shows the newly discovered planet-like object, dubbed "Sedna," in relation to other bodies in the Solar System, including Earth and its Moon; Pluto; and Quaoar, a planetoid beyond Pluto that was until now the largest known object beyond Pluto. The diameter of Sedna is slightly smaller than Pluto's but likely somewhat larger than Quaoar.
