In fact, researchers have spent decades combing the night sky for evidence of other planets at the far end of our own solar system. In February, researchers announced they had narrowed the search field for a hypothetical ninth planet beyond Neptune by nearly 80%, raising hopes that astronomers might soon solve this mystery.

How Scientists (Possibly) Found the Solar System''s Ninth Planet

Beyond Neptune, in the farthest reaches of our solar system, is Planet Nine. At least, that is what two Caltech professors believe. This isn''t a dwarf planet, like the recently downgraded Pluto.

Scientists Think a Giant, Unseen Planet Is Hiding in Our Solar System

There''s a good reason astronomers spend many hundreds of hours trying to locate a ninth planet, aka " Planet Nine" or "Planet X". And that''s because the Solar System as we know it doesn''t really make sense without it.

Is there a 9th planet out there? We may soon find out.

SCIENCE. Is there a 9th planet out there? We may soon find out. Starting in 2025 the Vera C. Rubin observatory will increase the number of known objects circling the sun by roughly tenfold,...

Batygin and Brown, strong advocates that Planet Nine exists, have been working on the search for Planet Nine since 2014, conducting computer simulations to test their theories against the

How Many Planets are in our Solar System? | Facts

These are the eight planets of our Solar System; however, there is a ninth, or at least, there used to be a ninth planet, namely Pluto. Pluto was considered the ninth planet of our Solar System until 2006, when it was

Where Is Planet Nine? Its Hiding Places Are Running Out

So a priori, it''s possible a planet might exist in the cold, dark depths of our own solar system. It could even be quite large, the size of an ice giant like Neptune . On supporting science

Dwarf Planets

Pluto is by far the most famous dwarf planet. Discovered by Clyde Tombaugh in 1930, Pluto was long considered our solar system''s ninth planet. But after other astronomers found similar intriguing worlds deeper in the distant Kuiper Belt – the IAU reclassified Pluto as a

Planet Nine is a hypothetical ninth planet in the outer region of the Solar System. 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). These ETNOs tend to make their closest approaches

There could still be a ninth planet in our solar system. Here''s why

,We all used to think there were nine planets. But in 2006, the solar system was left with only eight planets, when Pluto was no longer classified as such. But is it still possible there is a

Compelling evidence for a ninth planet in the Solar System

An artist''s impression of what ''Planet Nine'' could look like. Image: Caltech/R Hurt (IPAC). There''s strong new evidence that an undiscovered large planet exists on the fringes of our Solar System, according to two Caltech scientists who have looked at the odd behaviour of numerous distant Kuiper Belt Objects.

Searching for Planet Nine

The Solar System has eight planets. In 2006, astronomers reclassified Pluto as a dwarf planet, the same class as contains Eris, Sedna, Quaoar, Ceres and perhaps many more solar system small bodies. The notion that there may be a ninth massive planet in the outer solar system has taken on new appeal with recent data that show that the

New evidence for Planet 9 at the fringes of our solar system

In fact, Batygin said that a solar system without a Planet 9 can be ruled out with a confidence of five sigma. This value, for fields such as particle physics, is considered enough to declare a

Is Planet X/Planet Nine real?

Possible orbit of a perturbing "ninth planet" This diagram shows the orbits of a group of extreme trans-Neptunian objects (shown in magenta) that all somehow line up in a single direction. Another population of Kuiper belt objects have orbits (shown in cyan) that are perpendicular to the plane of the Solar System and clustered in orientation.

Planet Nine

"Now we can go and find this planet and make the solar system have nine planets once again." The paper is titled "Evidence for a Distant Giant Planet in the Solar System." Reference: "Evidence for a Distant Giant Planet in the Solar System" by Konstantin Batygin and Michael E. Brown, 20 January 2016, The Astronomical Journal.

Evidence for ''Planet 9'' may actually show our theory of gravity is

Evidence pointing toward the existence of an undiscovered ninth planet in the solar system may actually indicate our ideas of gravity are incorrect. If there is a planet 9, it is estimated to

Astronomers say a Neptune-sized planet lurks beyond Pluto

The solar system appears to have a new ninth planet. Today, two scientists announced evidence that a body nearly the size of Neptune—but as yet unseen—orbits the sun every 15,000 years. During the solar system''s infancy 4.5 billion years ago, they say, the giant planet was knocked out of the planet-forming region near the sun.
