Sedna (minor-planet designation: 90377 Sedna) is a dwarf planet in the outermost reaches of the Solar System, orbiting the Sun beyond the orbit of Neptune. Discovered in 2003, the planetoid's surface is one of the reddest known among Solar System bodies.
It was discovered on November 14, 2003 by astronomers Michael Brown, Chad Trujillo, and David Rabinowitz. Sedna is currently 88 Astronomical units (AU) from the Sun, which is three times the distance between Neptune and the Sun. Sedna's orbit is an ellipse and its aphelion is estimated to be 937 AU.

Astronomer Mike Brown, who co-discovered Sedna in 2003, believes it to be the most scientifically important trans-Neptunian object found to date, as understanding its peculiar orbit is likely to yield valuable information about the origin and early evolution of the Solar System.

Even without gravitational evidence, Mike Brown, the discoverer of Sedna, has argued that Sedna's 12,000-year orbit means that probability alone suggests that an Earth-sized object exists beyond Neptune. Sedna's orbit is so eccentric that it spends only a small fraction of its orbital period near the Sun, where it can be easily observed.
