Nov 15, 2022 · This black hole system, called Gaia BH1, is the closest ever observed to Earth and is made up of a Sun-like star just like our own orbiting a tiny, massive object, which El-Badry and co say is black hole. The observation suggests that black hole systems involving seemingly ordinary stars are likely to be much more common than originally thought.

Our solar system can be divided into three regions: the inner solar system, the outer solar system, and the Kuiper Belt and Oort Cloud. The inner, rocky planets are Mercury, Venus, Earth, and Mars. These worlds also are known as terrestrial planets because they have solid surfaces.

The answer is something like the newly discovered black hole-star binary system Gaia BH1, which contains the closest stellar-mass black hole to Earth ever discovered and a star orbiting it at an ...Such a small orbital period means the distance between the black hole and the companion star is only 2.5 times the Earth-Moon separation. Such a separation is too small to fit any low mass Sun-like stars, so the only type of star that can fit into this orbit with a black hole is a white dwarf. Furthermore, we were able to identify strong X-ray ...
