Chapter 15: Problem 46

Discuss the idea that 1 Ceres should be regarded as the smallest dwarf planet rather than the largest asteroid. What are the advantages of this scheme? What are the disadvantages?

Short Answer

Expert verified

Considering Ceres as the smallest dwarf planet rather than the largest asteroid could help refine classification of celestial bodies, and potentially stimulate more research due to the complex nature of dwarf planets. However, its size and its location within the asteroid belt might challenge this classification, potentially causing confusion and diluting the unique standing of Ceres. Thus, both perspectives have their benefits and drawbacks.

Step by step solution

Understand the Classifications

Start by defining what constitutes an asteroid and a dwarf planet. An asteroid is typically defined as a relatively small, inactive object, which is more like a planet's moon. A dwarf planet, on the other hand, is a celestial body that orbits the sun and has sufficient mass to assume a nearly round shape, but does not meet the other criteria that define a 'full-fledged' planet.

Arguments for Ceres as a Dwarf Planet

Present the evidence and rationale supporting that 1 Ceres could be classified as a dwarf planet. This includes its round shape due to its gravitational forces, its location in the asteroid belt, its differentiation into layers (core, mantle, crust), and its potential geologic activity.

Advantages of Ceres as a Dwarf Planet

Discuss the advantages of recognizing Ceres as a dwarf planet. This may include a more precise classification of celestial bodies and an increase in the total number of known dwarf planets. Moreover, observing Ceres as a dwarf planet could potentially offer more research opportunities, as dwarf planets are often considered more complex and diverse than asteroids.

Arguments Against Ceres as a Dwarf Planet

Consider the arguments for maintaining Ceres' status as an asteroid. This could refer to its size relative to other dwarf planets, with Ceres being significantly smaller, or to the fact that it's located within the asteroid belt, unlike recognized dwarf planets.

Disadvantages of Ceres as a Dwarf Planet

Discuss potential drawbacks of altering Ceres' standing to a dwarf planet. These might involve complications in classification methodology, potential confusion in academic and public sectors, or possible marginalization of Ceres due to its relatively small size compared to other dwarf planets.
