One thing I would emphasize from one of Joerg's message just a few messages
ago in this thread is to not start from the point of view of wanting to add
new sequence entries.

If instead you start from the assumption that every useful and/or
interesting sequence is *already* in the OEIS, you will find yourself
pleasantly surprised when a sequence with a straightforward definition is
not in the OEIS, nor any variation of it that you can think of.

Also look at the sequences pertaining to chemical elements. Thanks to the
periodic table, we can readily sort chemical elements that share a certain
property by atomic number. But as soon as we start trying to sort them by
weight of lightest or heaviest isotope, we're likely to run into problems
where we need to put a bunch of asterisks in the Data field.

Asterisks are my main problem with a lot of these planetary sequences.
