Hypothetical Objects are objects that have not yet been discovered but are thought to exist for certain reasons to explain phenomena across are solar system that has not been explained yet. Some hypothetical planets are false, due to being disproven to exist.
List[]
Here is a list of the other Hypothetical objects.
Regions in the Solar System[]
| Name of Hypothetical Region | Distance from Sun (in kilometers) | Diameter | Reason Hypothesized |
|---|---|---|---|
| Vulcanoid Belt | Less than Mercury's orbit. | Less than the diameter of Mercury's orbit. | It has no reason but was said to be a part of Vulcan and that it might be in Mercury's orbit. |
| Hills Cloud | 15,000 AU to 30,000 AU | 40,000 AU | Part of the Oort cloud. |
| Oort cloud | From 2,000 to 200,000 AU (0.03 to 3.2 light-years) | Between 0.8 and 3.2 light-years | Explain long period comets. |
