So it has come to light (1961 about) that the earth has these "Ghost" moons. Two of them in fact. You cannot land on them like we can our other moon. They are patches of cosmic dust that are in orbit about the earth. And it seems they have been for a very long time. It is really difficult to see these "moons" and that is why not much has been said about them.

I am still researching this as I want to understand the significance of cosmic dust orbiting us - and we taking the time to name it and classify it and analyse it. You can read what I found here
So Earth Apparently Has Two, Extra Hidden 'Moons'
 
There are objects that orbit the sun in 'resonance' with the earth, but they are not moons in any sense: https://en.wikipedia.org/wiki/Claimed_moons_of_Earth

2016 HO3, an asteroid discovered on 27 April 2016, is possibly the most stable quasi-satellite of Earth. As it orbits the Sun, 2016 HO3 appears to circle around Earth as well. It is too distant to be a true satellite of Earth, but is the best and most stable example of a quasi-satellite, a type of near-Earth object. They appear to orbit a point other than Earth itself, such as the orbital path of the NEO asteroid 3753 Cruithne. Earth trojans, such as 2010 TK7, are NEOs that orbit the Sun (not Earth) on the same orbital path as Earth, and appear to lead or follow Earth along the same orbital path.

AFAIK other moons in stable orbits around the earth's orbit are impossible, based on Newtonian dynamics (called the three body problem) and chaos theory.

Earth has one moon. Those are not "moons"

EDIT: What Gordon_R said.

That is interesting - and does ring a bell. Sure I have read that somewhere. I am still trying to find how dust clouds can be classified as "moons". I would have thought it would have to be a solid object at least.
 
Sun Likely Has a Long-Lost Twin
https://www.space.com/37186-sun-long-lost-twin-nemesis.html

For decades, some scientists have speculated that the sun has a companion whose gravitational tug periodically jostles comets out of their normal orbits, sending them careening toward Earth. The resulting impacts have caused mass extinctions, the thinking goes, which explains the putative star's nickname: Nemesis.

Now, a new study reports that almost all sun-like stars are likely born with companions, bolstering the case for the existence of Nemesis. [Solar Quiz: How Well Do You Know the Sun?]

"We are saying, yes, there probably was a Nemesis, a long time ago," study co-author Steven Stahler, a research astronomer at the University of California, Berkeley, said in a statement.
