Architecture of planetary systems can be defined by the correlations between properties of planets in a same system. In this work we studied the correlations between Earth-like planets and the other planets in their systems, particularly the "detectable" planets, in order to predict in which systems we can detect, in the future, Earth-like planets.

We used synthetic plaetary systems from the Bern model, allowing us to study entire planetary systems, in which we identified Earh-like planets and detectable planets, applying an observation bias. We then defined different architecture classes, using PCA, studied the properties of the innermost detectable planets and present now our discoveries: Earth-like planets are, indeed, correlated to some properties of their systems!
