In 2006, because of the rapid increase in "planet" discoveries, the International Astronomical Union re-defined the term "planet". The 2005 discovery of the Kuiper Belt Object called "Makemake" was therefore a "dwarf planet" rather than a real planet.
Sedna is not a moon of Saturn. It is a dwarf planet that is located in the outer parts of the Solar System. Sedna was discovered in 2003.
Sedna was discovered on November 14, 2003.
Pluto the 10th planet was discovered
If you count a dwarf planet, then yes: Eris was discovered in 2003 (but not identified until 2005). It is currently three times further from the sun than Pluto. Eris is larger than Pluto, and before the term "dwarf planet" was officially adopted in 2006, it was suggested that Eris had to be considered the solar system's tenth planet. If you don't count dwarf planets, then we actually lost a planet since the year 2000: In 2006, Pluto was downgraded from a planet to a "dwarf planet". In the year 2000 our solar system officially had nine planets, now it has eight. But it has three dwarf planets (Eris, Pluto, and Ceres).
The most distant planet in our solar system is Neptune. It is the eighth and farthest known planet from the Sun, with an average distance of about 4.5 billion kilometers (2.8 billion miles) from the Sun. Neptune is a gas giant, similar in composition to Uranus, and it has a blue color due to the presence of methane in its atmosphere.

Uranus is the second furthest planet from the sun. Neptune, now the furthest planet from the sun, was the second furthest planet from the sun after Pluto was discovered in 1930 until Pluto was reclassified as a dwarf planet in 2003.
A dwarf planet in the outermost reaches of the solar system, discovered in 2003. It has a diameter of approximately 1,400 kilometers and orbits beyond the Kuiper Belt. Its surface composition is largely a mixture of water, methane, and nitrogen ices with tholins, similar to those of some other trans-Neptunian objects.
No, Sedna and Nibiru are two different celestial bodies. Sedna is a trans-Neptunian object that orbits the sun in the outer reaches of the solar system, while Nibiru is a hypothetical planet often associated with conspiracy theories and doomsday predictions.

No, Cupid is not a planet. Cupid is an asteroid that belongs to the Amor group. It was discovered in 2003 and orbits the Sun in the asteroid belt between Mars and Jupiter.
Uranus is the second furthest planet from the sun. Neptune, now the furthest planet from the sun, was the second furthest planet from the sun after Pluto was discovered in 1930 until Pluto was reclassified as a dwarf planet in 2003.
