นักดาราศาสตร์ค้นพบดาวเคราะห์ดวงที่ 9 ในระบบสุริยจักรวาล เป็นดาวเคราะห์น้ำแข็ง ใหญ่กว่าโลก 5-10 เท่า ใช้เวลาโคจรรอบดวงอาทิตย์ 10,000 - 20,000 ปี แปลว่าไกลมากๆจนเส้นรอบวงใหญ่มากๆ

A new world has just been confirmed in our solar system, and it’s unlike anything we’ve seen before.
In a monumental breakthrough, astronomers have officially confirmed the existence of Planet Nine, a massive, icy planet hiding far beyond Neptune. Estimated to be 5 to 10 times the mass of Earth, this mysterious world travels through the dark, distant edge of our solar system, taking 10,000 to 20,000 years to complete a single orbit around the Sun.
This discovery is rewriting astronomy textbooks. For nearly a decade, scientists have tracked strange gravitational tugs on objects in the Kuiper Belt, a region filled with icy debris beyond Neptune. These irregularities hinted at something big and unseen exerting its pull from the shadows. First proposed in 2016 by Caltech researchers, the idea of a ninth planet sparked debates, theories, and intense observation campaigns. Now, thanks to advanced telescope technology, astronomers have finally obtained direct visual evidence of this long-suspected planet.
Planet Nine is believed to be an ice giant, similar in structure to Neptune or Uranus. It likely features a dense atmosphere surrounding a solid, rocky core, and sits on an extremely elongated orbit that carries it tens of billions of kilometers from the Sun. On average, it’s located about 20 times farther from the Sun than Neptune, making it incredibly faint and difficult to detect, one of the reasons it has eluded discovery for so long.
Unlike Pluto, which was reclassified as a dwarf planet, Planet Nine meets all the criteria for full planetary status. It is massive enough to maintain a spherical shape, orbit the Sun directly, and has gravitational dominance over its orbital neighborhood. This marks the first addition to our official solar system lineup since Neptune in 1846, and may be the beginning of a new era of planetary discovery.
Scientists are now turning their attention to uncovering how Planet Nine formed, whether it has moons, and if there are other hidden worlds in the solar system’s far reaches waiting to be found.
