How many planets are beyond Pluto?
What is beyond Pluto? There are at least eight more dwarf planets beyond Pluto and Neptune. They include Eris, a little bigger than Pluto, which has its own small moon. There is Haumea, Sedna, Orcus, Quaoar, Varuna, and Makemake.
Are there more planets past Pluto?
Because Pluto is no longer considered a planet by the IAU, this new hypothetical object has become known as Planet Nine….Pluto loses Planet X title.

Are there 9 planets?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. If you insist on including Pluto, it would come after Neptune on the list.
What is the most unknown planet?
- Planet Nine is a hypothetical planet in the outer region of the Solar System.
- Based on earlier considerations, this hypothetical super-Earth-sized planet would have had a predicted mass of five to ten times that of the Earth, and an elongated orbit 400 to 800 times as far from the Sun as the Earth.
How many other planets exist beyond Pluto?
Two or more unknown planets could exist beyond the orbit of Pluto in our solar system, new research suggests. (Image credit: NASA/JPL-Caltech) “Planet X” might actually exist — and so might “Planet Y.”
Could there be two planets larger than Earth?
“Planet X” might actually exist — and so might “Planet Y.”. At least two planets larger than Earth likely lurk in the dark depths of space far beyond Pluto, just waiting to be discovered, a new analysis of the orbits of “extreme trans-Neptunian objects” (ETNOs) suggests.
Is planet X hiding two giant planets beyond Pluto?
Just months after astronomers announced hints of a giant “Planet X” lurking beyond Pluto, a team in Spain says there may actually be two supersized planets hiding in the outer reaches of our solar system.
Is there another planet at the edge of our Solar System?
But no additional large planets have been found at the edge of our solar system. New calculations by astronomers in Spain and the UK suggest that not one, but two unknown planets might exist in our solar system, beyond Pluto’s orbit.
