“If Planet Nine is real, it would be on such an odd orbit and so far out in the outer Solar System, that it would really challenge our ideas of planet formation and dynamics,” Ann-Marie Madigan, assistant professor of astrophysics... Madigan isn’t searching for just one planet — she’s looking for an entire belt of celestial objects. Like Planet Nine, this proposed Zderic-Madigan, or ZM, belt would be really out there, far beyond the Kuiper belt, with some of its closest bodies being more than twice as far from the Sun as Pluto at perihelion. Unlike the Kuiper belt, this...

2015 TG387, a newfound object in the far outer solar system, way beyond Pluto. The orbit of 2015 TG387 shares peculiarities with those of other extremely far-flung bodies, which appear to have been shaped by the gravity of a very large object in that distant, frigid realm — the hypothesized Planet Nine, also known as Planet X. "These distant objects are like breadcrumbs leading us to Planet X," And 2015 TG387 is special among these bread crumbs, because it was found during a relatively uniform survey of the northern and southern skies rather than a targeted hunt for clustered objects...

Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles). In fact, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun. The researchers, Konstantin Batygin and Mike Brown, discovered the planet's existence through mathematical modeling...

Scientists have been wondering whether a "Planet X" exists in the dim regions far beyond the known planets, but it has remained largely speculative.... That started to change in March 2014, when a pair of astronomers announced that they’d discovered a brand-new dwarf planet, 2012 VP113, beyond the well-populated edge of the Kuiper belt, whose main mass stretches from Neptune’s orbit around 30 astronomical units (or 30 times the Earth-Sun distance) out to 50 astronomical units. It wasn’t the only such object: Sedna, a 600-mile-wide rock discovered in 2003, also boasted this far-out orbit, and it seemed to be making...

There might be a ninth planet in the solar system after all - and it is not Pluto. Two astronomers reported on Wednesday that they had compelling signs of something bigger and farther away — something that would definitely satisfy the current definition of a planet, where Pluto falls short. "We are pretty sure there's one out there," said Michael E. Brown, a professor of planetary astronomy at the California Institute of Technology. What Dr. Brown and a fellow Caltech professor, Konstantin Batygin, have not done is actually find that planet, so it would be premature to revise mnemonics of...

From the start, Sedna was an odd-ball. Its 11,400 year orbit takes it from a perihelion of 76 astronomical units (for context, Neptune is an average of 30 AUs from the Sun) to an amazing 936 AUs from the Sun. (A thousand AUs is 1.6% of a light year, and 0.4% of the way to Proxima Centauri, the closest star to our solar system). Currently at a distance of 86 AU and headed towards perihelion in 2076, we’re lucky we caught Sedna as it ‘neared’ (we use the term ‘near’ loosely in this case!) the Sun. But this strange path...

Presently, our solar system is known to contain 4 fully-fledged rocky worlds: Mercury, Venus, Earth and Mars; 2 ice-giants: Neptune and Uranus; 2 gas-giants, Saturn and Neptune; 5 dwarf-planets, Ceres. Pluto, Eris, MakeMake, Haumea; around 100 moons; and an unknowable number of comets, asteroids and minor planets. Indeed, we’ve only begun to understand the full scope of our local corner of our galaxy, and new information emerges on a monthly-basis, yet there a number of seemingly obvious things that remain unknown. For instance, long before Pluto’s existence was deduced, astronomers scoured the outer solar system in search of another large...

In their studies, the team analyzed the effects of what is called the ‘Kozai mechanism,’ which is related to the gravitational perturbation that a large body exerts on the orbit of another much smaller and further away object. They looked at how the highly eccentric comet 96P/Machholz1 is influenced by Jupiter (it will come near the orbit of Mercury in 2017, but it travels as much as 6 AU at aphelion) and it may “provide the key to explain the puzzling clustering of orbits around argument of perihelion close to 0° recently found for the population of ETNOs,” the team...

Explanation: What object has the furthest known orbit in our Solar System? In terms of how close it will ever get to the Sun, the new answer is 2012 VP113, an object currently over twice the distance of Pluto from the Sun. Pictured above is a series of discovery images taken with the Dark Energy Camera attached to the NOAO's Blanco 4-meter Telescope in Chile in 2012 and released last week. The distant object, seen moving on the lower right, is thought to be a dwarf planet like Pluto. Previously, the furthest known dwarf planet was Sedna, discovered in 2003....

Astronomers have increased the size of the observable solar system after spotting a 450-km wide object orbiting the sun. The lump of ice and rock circles the sun at a greater distance than any known object, and never gets closer than 12bn kilometres – 80 times the distance from Earth to the sun. If its size is confirmed it could qualify as a dwarf planet in the same category as Pluto. Though exciting in its own right, the discovery raises a more tantalising prospect for many astronomers: that a "Super Earth" up to 10 times the mass of our planet...

An international team of astronomers, led by Felipe Braga-Ribas (Observatório Nacional/MCTI, Rio de Janeiro, Brazil), has used telescopes at seven locations in South America, including the 1.54-metre Danish and TRAPPIST telescopes at ESO’s La Silla Observatory in Chile, to make a surprise discovery in the outer Solar System. This unexpected result raises several unanswered questions and is expected to provoke much debate. A press conference will be held in Brazil to present the new results and allow opportunities for questions. Note that all information regarding these findings is under strict embargo until 19:00 CET (15:00 BRT) on Wednesday 26 March...

It's official name is "2012 VP-113." But astronomers have nicknamed the newly discovered planet-like object on the edge of the solar system "Biden." Smiling Joe, nick-named for Vice President Joe Biden, is 7 billion miles away from the sun and has its own celestial body, The Washington Post reported. Biden is quite small at 280 miles in diameter, and scientists say it could be dwarf planet. Pluto, which was deemed a dwarf planet in 2006 has a diameter of 1,430 miles. By contrast, Earth is 7,900 miles across. It has a temperature of minus 430 degrees Fahrenheit and is likely...

Astronomers have nicknamed a new dwarf planet circling the sun at the outer edges of the solar system after Vice President Joe Biden. According to Nature, a leading scientific journal, the object's official designation is 2012 VP113. But the team studying its orbit around the sun colloquially refer to the planet as just "VP" or "Biden," after the sitting vice president. The object won't carry an official title until scientists collect more data. After determining its orbit, they'll submit a formal name to the International Astronomical Union (IAU) for consideration. The Biden dwarf is the second such object to be...

Scientists at the Carnegie Carnegie Institution for Science announced Wednesday the discovery of a new cosmic neighbor -- a distant dwarf planet named 2012 VP113 that was found spinning in the depths of space well past Pluto. Its existence suggests there may be another actual planet out there, they said, a rogue giant ten times bigger than Earth orbiting in the distant blackness

<p>LOS ANGELES (AP) — Peering into the far reaches of the solar system, astronomers have spied a pink frozen world 7½ billion miles from the sun.</p>
<p>It's the second such object to be discovered in a region of space beyond Pluto long considered a celestial wasteland. Until now, the lone known resident in this part of the solar system was an oddball dwarf planet spotted in 2003 named Sedna after the mythological Inuit goddess who created the sea creatures of the Arctic.</p>
