Which is the ninth planet discovered by NASA?
This hypothetical Neptune-sized planet orbits our Sun in a highly elongated orbit far beyond Pluto. The object, which the researchers have nicknamed “Planet Nine,” could have a mass about 10 times that of Earth and orbit about 20 times farther from the Sun on average than Neptune.
When was Planet 9 found?
When will Planet 9 be found? If there’s a giant planet lurking around the outskirts of our Solar System, astronomers will probably find evidence of it in the next 10 to 15 years. The next generation of telescopes, both in orbit and here on Earth, may increase astronomers’ chances of finding Planet Nine.
Where is the planet Xena located?
Jan 8, 2005: Scientists announce they have discovered a Pluto-sized world billions of miles beyond the orbit of Neptune. They nickname the tiny world Xena after a fictional television character. The discovery reignites a debate about the definition of a planet.
How was Planet 9 found?
Rowan-Robinson recently went digging into 38-year-old data and claims he has found the hypothetical Planet Nine. Although the recent claim is not a clear detection, it helps narrow down the area of the sky in which to look for this distant and mysterious planet.
What’s the name of the 10th planet?
Because Eris appeared to be larger than Pluto, NASA initially described it as the Solar System’s tenth planet….Eris (dwarf planet)

What is the name of the 11th planet?

What is Planet X or Planet Nine?
Planet Nine, sometimes referred to as Planet X, is a hypothetical planet in the outer region of the Solar System. Its gravitational effects could explain the unusual 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.
Is Xena the largest known Kuiper belt object?
Finding that the largest known Kuiper Belt object is a virtual twin to Pluto may only further complicate the debate about whether to categorize the large icy worlds that populate the belt as planets. If Pluto were considered to be the minimum size for a planet, then Xena would fulfill this criterion, too.
Is Xena bigger than Pluto?
Hubble Finds ‘Tenth Planet’ Slightly Larger Than Pluto 04.11.06 For the first time, NASA’s Hubble Space Telescope has seen distinctly the “tenth planet,” currently nicknamed “Xena,” and found that it’s only slightly larger than Pluto. Though previous ground-based observations suggested that Xena’s diameter was about 30 percent greater…
