The European Southern Observatory has discovered a black hole at the nearest distance. Will it threaten the earth?

The universe was born in a big bang 13.8 billion years ago. After the big bang, various celestial bodies were born. Among them, black holes are the most mysterious celestial bodies in the universe, and we humans know very little about black holes because of human history. Only a few million years, and the history of black holes may have been tens of billions of years.
