How planets are there in space apart from that Nine?
To date, astronomers have detected 307 extrasolar planets (that is, planets outside our solar system). As to how many there are in total, it’s impossible to say – there are at least 200 billion stars in our galaxy alone, and at our current ability to detect extrasolar planets, we can see at least 10% of stars have a planetary system, so you can estimate that there are many billions of planets in our galaxy, and no reason to assume the billions of other galaxies out there are any different.
