> If there were such a thing out there we could send a probe to it. You might be interested in Ed Witten's paper about this topic: "Searching for a Black Hole in the Outer Solar System", https://arxiv.org/abs/2004.14192 (See also this related comment from the HN discussion back then which puts Witten's paper into context very nicely: https://news.ycombinator.com/item?id=23135031 )

> I didn't recognize the name but figured he was the guy who came up with M-theory As it so happens, he's also the guy behind this paper: "Searching for a Black Hole in the Outer Solar System", https://arxiv.org/abs/2004.14192 :-)

> It's theorized that there is a grapefruit-sized black hole orbiting our sun in the outer reaches of our solar system with a mass of 5 to 10 earths. Source: https://arxiv.org/abs/2004.14192 (There was also a pretty good discussion about it here on HN.) > would probably be too small to notice without some sort of detection equipment. What makes you think that?

There is some gravitational anomaly in our solar system. There was a paper from earlier this year suggesting that it might be caused by a small black hole, although I guess there is no reason it couldn't also be caused by a wormhole. Edit: Here is the paper https://arxiv.org/abs/2004.14192. I misremembered it as a gravitational anomaly, but that is not completely inaccurate (it concerns the clustering of Kuiper belt orbits). The author (Ed Witten) proposes something similar to what you described for detecting the object.
