Sick of having just one planet per orbit? Need a location for your space habitat? Want to construct an interplanetary highway linking the various worlds in your system?…Welcome to the wonderful world of Lagrange points.
Here’s a little extra bit which was excluded from the video but was discussed down in the videos comments.
For added realism, place a terrestrial planet at the L4/L5 points of a gas giant. Why? Well, for ideal stability, the ratio of the masses between the secondary object (think earth) and a lagranian planet should be roughly 25:1.
That is a lagranian companion should not exceed 4% the mass of your main planet.
4% the mass of a terrestrial planet is doable…but bordering on implausible
4% the mass of a gas giant is a whole lot more plausible.
Plus setting up a system where the earth analog is a lagranian companion of a Hot jupiter say, brings that extra level of exotica to a setting.
A knock on effect of this this 25:1 mass ratio, is that a lagranian companion world is unlikely to have its own lagranian companion. This is because, by definition, lagrange points arise out of a thing called the restricted three body problem: three bodies, no more!
An orbit with a different, yet equally massive planet every 60 degrees is, simply put, utterly implausible
Unless your watching something like Firefly…THEN EVERYTHING’S PLAUSIBLE!
Happy Christmas everyone, look forward to hearing your lagranian anecdotes down in comments.
