According to the international astronomical union, the following rules govern all celestial bodies in our solar system.
A planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared* the neighbourhood around its orbit. A "dwarf planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared* the neighbourhood around its orbit, and (d) is not a satellite. All other objects, except satellites, orbiting the Sun shall be referred to collectively as "Small Solar System Bodies".
*Note: to have cleared its neighbourhood means the a celestial body is the dominant gravitational entity within its orbital zone, and that all other bodies within that zone act under the force of the body’s gravity.

1. If the same definitions for celestial bodies in our solar system are extended to celestial bodies that orbit the star Largo, which of the following can be concluded on the basis of the information given?
| For celestial bodies in the Largo system, mass and orbital period are positively correlated. | |
| There are no satellites that are part of the Largo system. | |
| The Largo system includes exactly three celestial bodies that meet the definition to be called planets. | |
| At least one small solar system body orbits the star Largo. | |
| Because HM 20321 d has not cleared its neighborhood, it must be subject to the gravitational force of one of the other bodies listed. |

2. The International Astronomical Union is extending its classification system to other solar systems, including the Largo system. In the grid below, select Planet if a celestial body from the Largo system has met the definition of a planet and Not a Planet if it has not.
| Planet | Not a Planet | |
| HM 20321 d | ||
| HM 21943 e | ||
| HM 21885 f |

This problem took me over 5 minutes before I was able to figure out the answers, so I'm leaving my explanation here:
Question 1: This is a process of elimination type question so let's go choice by choice:
A) Incorrect, if we look at the table, we can actually see this is false because the 21885 f is the smallest body, yet has the second longest orbit time.
B) Incorrect, if the answer said there were no satellites on Largo found YET, this answer would be correct; however, the passage says nothing about whether they found all the celestial bodies or not.
C) Incorrect, trap answer. If you go by the definition of what a planet is (has a round shape, cleared the neighborhood, and orbits the sun), there are three planets in the table that meet the criteria: b, c, and e. However, just like the last body, the passage never said that there were the only celestial bodies found.
D) Correct, 21885 f has an orbit even if it's irregular; additionally, it's the smallest celestial body so far, at least 10 times smaller than the next smallest one found so far.
E) Incorrect, similarly to answers B and C, there could be other celestial bodies that we don't know about.
Question2: Using the definition of a planet (has a round shape, orbits the sun, and cleared its neighborhood), let's go through these 1 by 1:
1) No, it didn't clear the neighborhood
2) Yes, this meets all 3 rules
3) No, it doesn't have a consistent orbit around the sun.
Therefore the answer is No, Yes, No

1. If the same definitions for celestial bodies in our solar system are extended to celestial bodies that orbit the star Largo, which of the following can be concluded on the basis of the information given?
A. For celestial bodies in the Largo system, mass and orbital period are positively correlated.
[*] No. This is a broad statement covering all or Largo system, while we have a small dataset of 6 bodies. So No
B. There are no satellites that are part of the Largo system.
[*] No. same reason as A.
C. The Largo system includes exactly three celestial bodies that meet the definition to be called planets.
[*] No. same reason as A.
D. At least one small solar system body orbits the star Largo.
[*] Yes. HM21885f has an irregular orbit and can be categorized as small celestial body. So we have at least one.
E. Because HM 20321 d has not cleared its neighborhood, it must be subject to the gravitational force of one of the other bodies listed.
[*] No. It could be subjected to gravitational force from any bodies in Largo system.
