Some of objects in our Solar System are NOT oficially recognized as a dwarf planet by IAU. Here are some examples:

Gonggong (2007 OR10): A massive trans-Neptunian object.

Quaoar: A large Kuiper belt object with a moon.

Sedna: A very distant planetoid with a highly elongated orbit.

Orcus: Often called the "anti-Pluto" due to its similar size and orbit.

Salacia: Considered a potential borderline dwarf planet.

so these space objects are NOT in the quiz.

Have a good one!
