The hypothetical Planet Nine is popularly attributed to the strange movements of objects in the outer solar system. Researchers now say these strange orbits could be explained by the collective force of smaller objects.

Astronomers think that Planet Nine exists at the edge of the Solar System. Here's one possible reason why the body remains elusive despite circumstantial evidence that it exists beyond planet Neptune.

A new theory suggests gravity of smaller space debris could explain the strange orbits of Sedna and other trans-Neptunian objects. Here's why it failed to debunk the existence of Planet Nine.

New evidence shows that Planet Nine may not exist after all and collective gravity may be to blame for some of the evidence of the missing planet. This would throw off calculations expecting a planet.

A five-year survey of the outer reaches of the solar system has led scientists to discover as many as 840 previously unknown small planets. They believe there could be as many as 90,000 little icy worlds more.

Scientists have theorized that there may be a ninth planet in the solar system due to strange orbits that many Trans Neptunian objects have. One of those objects may have just delivered evidence of a ninth planet.

Researchers believe that medieval tapestries might contain proof that 'Planet Nine' exists in the solar system. Scientists are still searching the skies trying to find the mysterious planet.

A now-viral report posed the possibility of Planet X finally being seen on April 23. The planet, also known as Nibiru and Planet 9, would supposedly become visible with other astronomical bodies, signaling the end of times.

NASA is getting close to finally finding the mysterious Planet Nine, as Caltech researchers have presented new evidence for its existence. NASA also reiterated that Planet Nine, Nibiru, or whatever people want to call it, will not collide with Earth.

New observations offer evidence that a Planet 10 may be hiding closer to home based on its effects on Kuiper Belt objects. How does this affect the search for Planet 9 and other worlds in the outer solar system?

Planet Nine may not exist, but that doesn't mean there are only eight planets in our solar system. The orbit of certain celestial bodies suggests there might be a smaller planet at the edge of our solar system.

Astronomers first spotted the distant celestial object UZ224 in 2014. After years of observation, they reveal that 'DeeDee' meets all the new requirements to be considered a dwarf planet.

In a citizen science project using images from the SkyMapper telescope, researchers from the Australian National University have identified four likely Planet Nine candidates. Will one of these objects end the elusive search?
Space April 4, 2017
Australian astronomers have released thousands of images for the public to help pinpoint the location of Planet Nine. The images were captured by the SkyMapper telescope and go by the thousands.

Ever dreamed of being an astronomer? NASA wants your help finding an elusive and mysterious planet called Planet Nine, which scientists believe is located beyond Neptune.
Space February 17, 2017
A new study proposes that Planet Nine could previously be a 'rogue planet,' a free-moving body not bound to any host star, which eventually got snatched into the solar system through the sun’s gravitational pull.
Space January 13, 2017
The discovery of more objects beyond Neptune has strengthened hopes of locating the elusive Planet Nine. The presence of three more trans-Neptunian objects (TNOs), in addition to the existing six, supports evidence about Planet Nine’s existence.

The sun's odd tilt relative to the orbital plane of the other planets could be attributed to a massive object lying in the far outer solar system. The findings support the idea of the existence of the theoretical Planet Nine.
Space October 20, 2016
The trans-Neptunian object called Niku orbits the sun in a plane tilted 110 degrees to the plane of the rest of the bodies in the solar system and orbits backwards. Is the hypothetical Planet Nine responsible for this odd behavior?

Heard about Planet Nine? The theoretical planet is getting many astronomers all fired up trying to know what, where, and how it is, so here’s a guide for you.
Space April 10, 2016
Planet Nine could have been stolen by the sun when a close star passed by, researchers found. This challenges a first theory that the ninth planet is originally of the solar system and migrated to its edge.
Space April 9, 2016
Some observations on the Cassini spacecraft, which is orbiting Saturn, are fueling hope that the elusive Planet Nine may soon be detected.

Planet nine may orbit in the depths of the solar system, frigid and massive. What would conditions be like on this frozen world?
Space April 7, 2016
The hypothetical Planet Nine may or may not exist beyond the outer solar system, but scientists believe they found new evidence to support its presence. The evidence is supported by eccentric objects lining up in the Kuiper Belt.

Find Planet Nine! In the quest to find our solar system's assumed ninth planet, French scientists said, by using mathematical models, they were able to narrow down its location by almost 50 percent.
Space February 25, 2016
NASA said that there is no actual proof yet that Planet 9 exists - it remains a theory up to this day. Computer simulations, however, recently attributed the alignment of some bodies beyond Neptune to the effects of a planet about 30 billion kilometers from the sun.
