Constraints P2243 and P2233[edit]

Comets like Comet Lulin (Q477976) should not have properties like apoapsis (P2243) and semi-major axis (P2233) (or they should be "novalue"). But I guess it is better to make exceptions for them, than removing these Constraints. -- Innocent bystander (talk) 11:49, 20 October 2015 (UTC)
