Which statement about dwarf planets is true?

• A. They are not required to clear their orbital paths.
• B. They clear their orbital paths.
• C. They orbit black holes.
• D. They are always larger than planets.

Answer: (A)

Dwarf planets are defined by orbiting the Sun, being nearly round in shape, and not having cleared their neighboring region of other objects. Because they haven’t cleared that area, they share their orbital zone with other bodies of similar size rather than dominating the region. That’s why the statement about not needing to clear their orbital paths is the true one. They do not orbit black holes, and their size isn’t what automatically makes them planets or not—dwarf planets are typically smaller in their ability to clear their surroundings, not necessarily in overall size. Pluto is a good example: it orbits the Sun and is rounded, but it shares its orbital neighborhood with many other Kuiper Belt objects.
