How many worlds exist in our galaxy?
Sources:
In the Milky Way, there might be as many rogue planets as there are stars, according to Sara Seager in her discussion with Lex Fridman. This suggests a significant number of worlds, or planets, potentially matching or even surpassing the number of stars which is estimated in the hundreds of billions. Each of these stars is likely to have its planets, as most stars are believed to host at least one planet. Therefore, the number of worlds in the Milky Way could be extraordinarily vast, possibly in the hundreds of billions or more 1.
