Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. [4] [2] Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth i.e. over 250 astronomical units (AU).
Scientists say they have found new evidence that there is a hidden planet in our solar system. For years, some astronomers have been suggesting that unusual behaviour on the edge of our solar ...
Planet nine may be orbiting far from the Sun, at the edge of our solar system. Astronomers, seeing odd irregularities in the orbits of the outer planets suspect another, unknown, planet may orbit ...
The new Hayden Planetarium (often called "The Hayden Sphere" or "The Great Sphere") is one of the two main attractions within the Rose Center. The original Hayden Planetarium was established by the State of New York in 1933, with some of the funding coming from philanthropist Charles Hayden. [7]
Backyard Worlds: Planet 9 is a NASA-funded citizen science project which is part of the Zooniverse web portal. [1] It aims to discover new brown dwarfs, faint objects that are less massive than stars, some of which might be among the nearest neighbors of the Solar System, and might conceivably detect the hypothesized Planet Nine.
By RYAN GORMAN Scientists may have found Planet X -- the long-rumored object believed to be larger than Earth and further from the sun than Pluto. Planet X and another object dubbed "Planet Y ...
Nonetheless, an article in the British tabloid The Sun (later republished in the New York Post) [124] conflated the three ideas of Nibiru, Planet Nine, and Whitmire's planet to suggest that not only had Planet Nine been found, but that it would collide with Earth at the end of April, which resulted in Batygin receiving a spike in panicked calls ...
