Recently have been binge-ing on planets and cosmos, and I saw this youtuber mentioned that we might discover the next planet after Neptune.
However from my understanding, humanity has discovered black holes, magnetars, stars and so on that are hundreds, thousands or even more than that in terms of the measurement of light years.
Our solar system is not in the measurement of light years, yet we can’t discover the next planet after Neptune. Why ?
In: Technology
A common way we detect exoplanets is by seeing stars dim just a tiny bit as their planets pass between the star and our telescope. Planets in our own solar system beyond our orbit will never be between us and the sun, so all we have to go on is the absolutely tiny amount of light that gets all the way out there and then back to us, and that’s hard to see.
