"We are currently working to better quantify how we might be able to infer their presence indirectly," Michael Tremmel, a postdoctoral fellow at the Yale Center for Astronomy and Astrophysics
, and lead author of the study, said in (https://news.yale.edu/2018/04/24/study-milky-ways-supermassive-black-hole-may-have-unseen-siblings) a statement.
"It is extremely unlikely that any wandering supermassive black hole will come close enough to our Sun to have any impact on our solar system," said lead author Michael Tremmel, a postdoctoral fellow at the Yale Center for Astronomy and Astrophysics
. "We estimate that a close approach of one of these wanderers that is able to affect our solar system should occur every 100 billion years or so, or nearly 10 times the age of the universe."
