We have up to SIX new Planet Xs that have been discovered within our Solar System by multiple Astronomer teams. Team 1: ‘The 13 Objects’ Team, Team 2 : GNA & Team 3 :W Aquilae.
This is totally fascinating.
Other Astronomers and Science communicators are quick to doubt all of the findings. Very Interesting.
God Bless everyone,

‘The Serendipitous Discovery of a New Solar System Object with ALMA’
Article by Phil Plait
“Team One: W Aql
Both teams used observations from the Atacama Large Millimeter/submillimeter Array (or ALMA). One team was observing the nearby star Alpha Centauri (or Alpha Cen for short), and the other team the more distant W Aquilae (or W Aql).
The latter observation is easier to explain, so I’ll start there. They observed W Aql in March and again in April 2014. They saw a source in the first observation that appeared to move by the time of the second. A third observation was made in May 2014, but nothing was seen. Given how much it appeared to move, and how bright it is, they conclude it is consistent with an object in the solar system, no farther than about 600 billion kilometers from the Sun.
If it’s far away it could be a planet-sized object, but if it’s closer it would have to be smaller. It could be one of the smaller icy worlds well outside Neptune’s orbit; it’s suspected million may exist with diameters of a few hundred or thousand km. Heck, Pluto and Eris are (large) examples of them, and different populations of them may extend past Neptune for hundreds of billions of km. So it’s not too weird to wonder if this were one of those (and to be honest, if this is real, I’d bet this is what it is).
Or it might not exist at all. Bear that in mind.
Team Two: Alpha Cen
The second team were looking for planets around the two stars that make up the binary system of Alpha Centauri, the nearest star system in space to the Sun. One planet was claimed to have been found in 2012, but since then has fallen into controversy. Another group looked at the data and said the planet was a spurious result; in other words, not real.
Still, that doesn’t mean there isn’t a planet there. The problem is, the stars are so bright they’d drown out any much fainter nearby planets. Looking at longer wavelength light makes that easier; the stars don’t put out much light at those wavelengths, while planets (which are much cooler than stars) might. That makes the huge contrast far less an issue. That’s why the astronomers used ALMA, which sees light in the millimeter wavelength range (the light we see with our eyes has a wavelength more like 500 nanometers, far shorter.)
They observed Alpha Centauri twice; once in July 2014 and again in May 2015. Like the first team, they too saw a moving source (see the picture at the top of the post). And, to their surprise, it moved along more or less with the stars!”
