    I'm wondering something similar: How long before a planet is simply ejected into interstellar space? If it can happen to Mercury here in Sol's tepid system, it could happen anywhere.

    I believe it is generally thought that space is teeming with just such ejected planets wandering about and getting in the way of starships.

    Carbon stars. Tonight, while waiting for Luna to rise, I experimented with making a "tour" list of Carbon Stars for the EQTours program that controls the telescope from the laptop. I got the coords from the CSOG project files. I had to go through the Constellation lists and copy-paste the Carbon Stars from there into a new list. The CSOG Constellation lists are in alphabetical order for the whole sky, N and S both, so it took a while to separate out only those Carbon Stars that can be seen from the N hemisphere. Once the list is made in the right format, then EQTours can tell what's above the local horizon (or in my case 35 degrees above the actual horizon, because trees) and only present possibles for viewing.

    And it worked! So I viewed about a dozen Carbon Stars in Cassiopeia and Cygnus before it got too cold.

    They are indeed remarkable. Like glowing red coals, among a field of ordinary bluewhite diamonds. Some are incredibly deep red. One can almost imagine them flickering (many do vary greatly in magnitude on a timescale of days or weeks) and smoking, blowing off carbon soot and carbon monoxide.

    Although the negative mass would come in very handy, it must be said.
