Largest Black wholes in our solar system part 1

The largest black holes in the universe are formed when high-mass stars die. Larger yet, the largest black holes in our solar system are formed by supermassive black holes in the center of galaxies, which grow as they swallow up smaller particles of matter. A collision occurs between clouds of gas at a galaxy's center and these clouds swirl around one another, eventually colliding and forming a larger mass.

Phoenix A

Phoenix A is the largest known black hole in our solar system. It's a supermassive black hole, which is found at the center of most galaxies. The black hole was first discovered in 2005 and was thought to be about four times more massive than the Sun.

In 2014, scientists discovered that Phoenix A has a companion black hole about 4,000 years old. This means that Phoenix A may not be as massive as originally thought.

Phoenix B is also called the Lagoon Nebula L1, or NGC 6520. It belongs to a small group of nebulae that are located near the center of our galaxy and can be seen with binoculars or a telescope.

The Lagoon Nebula has been described as an "asterisk" because it's much smaller than other nebulae in our galaxy. It's only 3 light-years across, but it's still very large compared with other objects found around black holes.

TON 618

The TON-618 is a black hole that is about 618 miles in diameter and has a mass of 12 billion times the mass of our sun. It is located in the Milky Way galaxy and not far from the center of its parent galaxy. This black hole has been studied extensively by astronomers and astrophysicists since its discovery in 2014.

The TON-618 was discovered by NASA's Chandra X-ray Observatory. The telescope observed faint X-ray emission from this object, which indicated that it was a black hole with a mass at least 12 billion times more massive than our sun.

The first time this black hole was discovered was by an amateur astronomer named Michael Reiss who spotted it while trying to find an asteroid near Mars. He called his discovery "the Killer Asteroid" because he thought there might be another asteroid or comet that would collide with Earth at some point in the future.

Holmberg 15A

The Holmberg 15A is the largest black hole in our solar system. It is located at the center of our galaxy, the Milky Way, and has a mass of 6.6 billion times that of our sun.

The Holmberg 15A is also known as Sagittarius A* or Sgr A*. This black hole has a diameter of about 8 million miles (12 million km). It's so big that it swallows up all the other stars in its vicinity, including many other stars within only a few thousand light-years away as well as gas and dust.

It is thought that this black hole was formed when a massive star exploded as a supernova — but not all of its material came from that star. The remaining core may have been created by a merger between two galaxies or clusters of galaxies, which would have been much smaller than our own galaxy now.

NGC 6166

NGC 6166 is a black hole that was discovered in 1994 by the Hubble Space Telescope. It is located 1,500 light years from Earth, in the constellation of Cygnus.

The size of NGC 6166 is estimated to be about 2 million times the mass of our Sun. This makes it about two and half times larger than the Milky Way's central black hole. The star that orbits this black hole has been calculated to be about 10 times more massive than our Sun and has been named V838 Monocerotis after its spectral type (V838 Monocerotis).
