The post Astronomers identified a dwarf-planet candidate beyond Neptune in 2025 whose orbit lasts nearly 24,000 years and carries it beyond the survey’s detection range for 99.5% of the journey — so finding even one suggests roughly 200 similar worlds may be circling unseen. appeared first on Space Daily .
