What is known about Planet X?
The Caltech scientists believe Planet X may have has a mass about 10 times that of Earth and be similar in size to Uranus or Neptune. The predicted orbit is about 20 times farther from our Sun on average than Neptune (which orbits the Sun at an average distance of 2.8 billion miles).
Does planet9 exist?
Unless Planet Nine is observed, its existence is purely conjectural. Several alternative hypotheses have been proposed to explain the observed clustering of trans-Neptunian objects (TNOs)….Planet Nine.
| Orbital characteristics | |
|---|---|
| Mass | 6.3 +2.3 −1.5 M Earth |
| Apparent magnitude | ~21 |
Is there a planet called Pelagos?
Pelagos is a sea planet teeming with intelligent kelp.
How was Planet X formed?
It likely formed in the inner Solar System and got flung outward, perhaps by Jupiter or Saturn. “That would suggest a lot of big things formed in our Solar System, and it was a very chaotic place in the formation era,” says Sheppard. But before those questions can be answered, Planet X must be found.
What would Planet 9 be called?
The alleged “Planet Nine,” also called “Planet X,” is believed to be about 10 times the mass of Earth and 5,000 times the mass of Pluto.

What planet is Uranus?
Uranus is the seventh planet from the Sun, and has the third-largest diameter in our solar system. It was the first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.
Where is Pluto now?
Dwarf Planet Pluto is currently in the constellation of Sagittarius.
How old is the earth?

Earth/Age
Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.

What are some facts about Planet X?
Planet X is a hypothetical planet that is located about 400 astronomical units (AU) away.
What is the truth about Planet X?
The Caltech scientists believe Planet X may have has a mass about 10 times that of Earth and be similar in size to Uranus or Neptune. The predicted orbit is about 20 times farther from our Sun on average than Neptune (which orbits the Sun at an average distance of 2.8 billion miles).
Is planet X a real thing?
Planet X is the supposedly eleventh planet of our solar system. It should be as big as many Earths, dwarfing it perhaps even hundreds of times. Some people think X isn t even a real planet, but a `brown dwarf : a massive ball of dust and gas that almost succeeded in becoming a star.
Does planet X really exist?
Planet X is a hypothetical planet purported to be on a collision course with the Earth, though this hypothesis has been refuted by most of the mainstream astronomical community. However, there is strong evidence for the presence of a number of large objects in the Oort cloud outside Pluto’s orbit.
