Scores of conspiracy theorists expected the mysterious Planet X, known as Nibiru, to arrive in the skies on Saturday, September 23, to herald the apocalypse.
The spectacular theory gained a lot of traction and media attention but the world continues.
Nibiru which is said to orbit the sun every 3,600 years and is 10 times the size of Earth, was nowhere to be seen. But oddly enough, something else appeared in the night skies.
After one shocked Londoner claimed to have filmed Planet X UFOs dashing over London on Sunday, similar footage emerged from the US.
Several freaked out residents of Los Angeles, California took to social media on Sunday, September 24, to share videos and photos of what appears to be a crescent shaped object flying through the skies.
Some have speculated about the object being extraterrestrial in nature, while others quickly dismissed it as a shooting star or plane.
Writer and film critic Andy Signore tweeted: “We totally just saw #UFO over Los Angeles! Crazy crescent wing out of light, sputtered slowly, then zoomed outta here! That was nuts.”
Fon H Davis also tweeted: “So this just #UFO just flew over Los Angeles. What is it? A meteor perhaps? Not a missile we hope.”
Someone also described the object as a “burning light stationary in the sky”.
According to UFO conspiracy website UFOs.com, the object had a smooth fiery trail, and was too small to be a helicopter.
The spectacular nature of the unidentified object led some to speculate that it was somehow connected to the alien planet Nibiru.
Ricky Salinas said: “Just saw a f**** Meteorite or UFO over Pasadena am I the only one that saw that?”
As the Nibiru panic quickly spread through Los Angeles, evidence came to to suggest the object was in fact spacecraft – but not alien.
Late last night, California’s Vandenberg Air Force Base launched a brand new NROL-42 spy satellite at around 1:49 a.m. EDT. The same time that the ‘UFO’ was spotted.
The NROL-42 will join the ranks of the United State’s National Reconnaissance Office (NRO) satellites in orbit around Earth.
Colonel Gregory Wood, 30th Space Wing vice commander, said: “This launch is the culmination of many months of work by United Launch Alliance, the National Reconnaissance Office and the 30th Space Wing.
“All of Team Vandenberg is dedicated to mission success and proud to play a part in delivering these capabilities to our nation.”
To further illustrate the the object had no connection to the mystical Planet X, Nasa have repeatedly rejected claims of the planet’s existence.
Nasa’s leading scientist Dr David Morrison said: “There is no credible evidence whatever for the existence of Nibiru. There are no pictures, no tracking, no astronomical observations.
“I can quite specifically say how we know Planet X or Nibiru does not exist and does not threaten the Earth.”
