Farout: the most-distant body ever observed in Solar System

Researchers discovered the farthest known object in our solar system and named it “Farout” (far-out-there). It is about 120 times farther than Earth is from the Sun (120 AU Notes 1). For comparison, the most distant planet, Neptune is about 30 AU from the Sun. At its most distant, once upon a time the ninth planet, now a dwarf planet, Pluto, can be 49 AU (7.29 billion km, or 4.53 billion miles) from the Sun. Currently, Pluto is at about 34 AU, making  Farout more than three-and-a-half times more distant than the Solar System’s most-famous dwarf planet.

Watch: Yet Another Scale Model of the Solar System

Previously I posted articles titled “If The Moon Were Only 1 Pixel – A Tediously Accurate Map Of The Solar System” and “A Scale Model Of Solar System Drawn In The Desert And The Result Is Stunning”. Since the human brain cannot deal with the really large numbers, these articles provide amazing ways to understand how big actually our Solar System is.

Now, in his YouTube channel, The Science Asylum, physicist Nick Lucid provides yet another scale model of the solar system. A very nice video conceptualizing how mind-bogglingly big our solar system (and space) is.

Watch: 12 Years Ago, New Horizons’ fantastic voyage began with a spectacular launch

Twelve years ago, on January 19, 2006, aboard an Atlas V rocket, NASA’s New Horizons probe started its fantastic voyage of exploration with a spectacular launch from the Florida coast toward Pluto and the mysterious realm of the Kuiper Belt beyond.

Video: two views of launch of NASA’s New Horizons spacecraft aboard an Atlas V rocket on January 19, 2006, from Cape Canaveral Air Force Station, Fla. New Horizons was the fastest spacecraft ever launched, leaving Earth at approximately 16.26 kilometers per second (58,536 km/h; 36,373 mph).

Planet Nine – Where is it?

In January 2015, Caltech (California Institute of Technology) astronomers Konstantin Batygin and Michael E. Brown published an article titled Evidence For A Distant Giant Planet In The Solar System and announced calculation-based evidence of a massive ninth planet. Despite they have had started their research to demonstrate that there’s no ninth planet, they reached the exact opposite result: there must be a ninth planet beyond Pluto, and it’s probably 10 times the mass of Earth (for comparison, Neptune has 17 times as much mass compared to the Earth).

In an effort to state Planet Nine’s exact location, a team of French scientists used the data from the Cassini–Huygens (an unmanned spacecraft orbiting Saturn, launched on October 15, 1997). They couldn’t able to find the exact location of the giant planet, but they narrowed down the “possible areas”.

Astronomers Think They’ve Found Evidence for a Ninth Planet Beyond Pluto – And It’s a Giant!

Astronomers now think there’s a ninth planet in the solar system almost certainly. The farthest planet from our Sun is probably a giant, smaller than Neptune but likely larger than the Earth. It is informally called Phattie, but commonly known as Planet Nine.
