So an orbital resonance is when two objects orbiting around something else
00:25
have orbital periods that are a simple ratio of each other.
00:29
So, for example, if one object goes around in one year
00:34
and another object goes around in two years, then that is a two-to-one resonance.

The reason why this planetary system is therefore interesting
00:53
is that actually many planetary systems don't have these orbital resonances
00:57
despite the fact that they are somewhat stable.
01:00
And that's because we think that over time, as planets are evolving
01:04
and the solar system is changing, they get knocked out.
01:07
Not literally whacking into one another, but getting slightly pushed away.
01:11
And so we end up with a number of planetary systems out there
01:15
which are close to being an orbital resonance,
01:18
but few that are actually in these resonances.
