| You're welcome. Good fix on the A question, unfortunately your K question is still wrong. The objects in the Kuiper Belt are not comets, as they are not close enough to the sun to develop a coma. Nor are they likely to become comets, as they are in relatively stable orbits. For example, Pluto is in a 3:2 resonance with Neptune. It's the scattered disc, where Eris resides, that is thought to be the source of short period comets, as Neptune's gravity disrupts their orbits over millions of years. For K, I'd suggest going back to the original clue, but change the dwarf planets to PLuto, Haumea and Makemake, which are all Kuiper Belt members. |
