Based on the IAU's adopted rules for classification as a planet, why should an object closer to the Sun be more likely to qualify as a planet?%0D%0A%0D%0A(1 point)%0D%0AResponses%0D%0A%0D%0AThere are fewer large asteroids close to the Sun.%0D%0AThere are fewer large asteroids close to the Sun.%0D%0A%0D%0AProximity to the Sun causes objects to be bigger%0D%0AProximity to the Sun causes objects to be bigger%0D%0A%0D%0AObjects near the Sun are more likely to be round.%0D%0AObjects near the Sun are more likely to be round.%0D%0A%0D%0AObjects close to the Sun are warmer
Compared to objects in the outer regions of the solar system, objects close to the Sun are more likely to qualify as a planet based on the IAU's adopted rules for classification. Here are the reasons for this:
1. Objects near the Sun are more likely to be round: According to the IAU's definition, a planet must be round due to its own gravitational forces. Objects closer to the Sun experience stronger gravitational forces, which compresses them into a spherical shape over time.
2. Proximity to the Sun causes objects to be bigger: The gravitational pull of the Sun attracts more material towards its vicinity, leading to larger objects. This means that objects closer to the Sun are more likely to reach the required size threshold to be considered a planet.
3. Objects close to the Sun are warmer: The increased proximity to the Sun results in higher temperatures, which can have various effects on objects. This warmth can cause volatile substances to vaporize, leading to activity like outgassing or the presence of an atmosphere. These characteristics can also contribute to meeting the criteria for planetary classification.
Overall, these factors make objects closer to the Sun more likely to qualify as planets according to the IAU's rules.
