Very coolMommy, where do baby planets come from? There's no storks, birds, bees, or romantic dinners for two involved in the answer to that question - regardless of size, planets are all formed in pretty much the same way: through the aggregation of material within the disk of dust and gas surrounding a young star. While how long it actually takes and just what sort of planets are most likely to form where are still topics of discussion among astronomers, the birth process of a planet is fairly well understood.
