I am informed that later in the month we will have 22/2/22 22:22… a twosday! 8-P (Tuesday 22 February 2022).

Nelson's word yesterday was 'viewing' and todays’ was ‘fog’, but I didn’t draw anything for that. 

I did a little code last night, not following up on my triangles or the heart shape from Monday night but generating an inner star system with worlds ranging from super earths on down to mars or moon sized bits. The inner system goes to bigger worlds if the silicate band precipitates before the frost line starts making gas and ice giants. Kuiper belt objects come from a band of carbon monoxide precipitating outside the main part of the star system. If the middle band comes along first and dominates, that we get larger gas giants stealing mass away from the inner system or even ‘tacking’ all the way in to become hot Jupiters or Neptunes. These could be nested binaries or nested on a continuum.

I want to have a system which rarely throws out a sol-type star system, where the average density of the planetary disk is about ten times what we saw to make Earth, Mars and the rest, based on what a seed protoplanet can gather in its lane. Mostly we get super Earths, and when we do the giants get a little less stolen rock in the mix with their gas. This isn’t very scientific but I will have the rocky bits govern how much gas is gathered, with a random factor. Then, sometimes, these giants ‘tack’ in-system, if they get carried away with hoovering up rocky bits of the inner system. I can make a ‘roll’ versus that inner system density, if less than one and if the roll is over that number, so for 10% we have a 90% chance of hot giants in close. The inner giant has its’ orbit reduced by some factor and gets most of the rocky bits. Other giants may follow it in and get some leftovers.
