The Milky Way’s largest black hole is Sagittarius A (Sgr A)**.

• Type: Supermassive black hole
• Location: Center of the Milky Way galaxy
• Mass: Approximately 4.3 million times the mass of the Sun
  While there are other black holes in the Milky Way, Sgr A* significantly surpasses them in size and mass.

The Milky Way’s largest black hole is Sagittarius A (Sgr A)**.

• Type: Supermassive black hole
• Location: Center of the Milky Way galaxy
• surpasses them in size and mass.

Sagittarius A* (Sgr A*) is the supermassive black hole located at the very center of the Milky Way galaxy.
Here are some key facts about it:

• Location: It resides in the constellation Sagittarius, approximately 26,000 light-years away from Earth.
• Mass: It has a mass estimated to be about 4.3 million times that of our Sun.
• Size: Its event horizon, the point of no return, has a diameter of roughly 14.6 million miles (23.5 million kilometers).
• Activity: While it’s a supermassive black hole, Sgr A* is relatively quiet, meaning it doesn’t actively consume a lot of matter.
  Discovery and Significance
• Early Observations: Astronomers first detected a strong radio source in this region in the 1930s.
• Confirmation as a Black Hole: Over the decades, observations of stars orbiting the galactic center at incredibly high speeds provided strong evidence for the presence of a supermassive black hole.
• Nobel Prize: In 2020, Reinhard Genzel and Andrea Ghez were awarded the Nobel Prize in Physics for their groundbreaking work in proving the existence of Sgr A*.
  Recent Developments
• First Image: In 2022, the Event Horizon Telescope (EHT) collaboration released the first-ever image of Sgr A*, providing direct visual confirmation of its existence.

Sgr A* continues to be a subject of intense research, offering valuable insights into the behavior of black holes and their role in galaxy formation and evolution.

The closest known black hole to Earth is Gaia BH1, located about 1,560 light-years away in the constellation Ophiuchus.
It’s important to note that while this is the closest known black hole, there could potentially be others even closer that we haven’t yet discovered.
Black holes are fascinating and mysterious objects, and our understanding of them is constantly evolving as new discoveries are made.

The largest known black hole in the Milky Way is Gaia BH3, which is located 2,000 light-years from Earth in the constellation Aquila: 

• SizeGaia BH3 is 33 times the mass of the Sun. 
• DiscoveryThe European Space Agency’s Gaia mission discovered Gaia BH3 by observing a star’s unusual wobbling. The wobbling indicated that the star was orbiting a dormant black hole with a high mass. 
• ProximityGaia BH3 is the second-closest known black hole to Earth, after Gaia BH1, which is 1,500 light-years away. 
• Companion starGaia BH3’s companion star likely formed within two billion years of the Big Bang. It orbits in the opposite direction to most Milky Way stars, which suggests it may have come from another galaxy that merged with ours. 
• TheoryThere are likely thousands or millions of black holes in the Milky Way that are still hidden, though only about 50 are currently confirmed or suspected. 

What is the black hole next to the Milky Way?

Sagittarius A*

Though Sagittarius A* is more than 26,000 light years (152 quadrillion miles) away from Earth, it is our closest supermassive black hole. Its formation and physical processes influence our galaxy as galactic matter continually crosses the event horizon, growing the black hole’s mass

Which is bigger, Sagittarius A or TON 618?

Sagittarius A* is the supermassive black hole at the center of the Milky Way. Ton 618 is one of the largest black holes ever discovered. The size difference between them is almost unbelievable. Ton 618 is 27,000x larger than Sgr A* in terms of diameter, and 15,000x more massive.

Will a black hole hit Earth?

In May 2022, astronomers revealed the first ever photograph of the black hole at the centre of our Galaxy. Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe

Do white holes exist?

The negative square root solution inside the horizon represents a white hole. A white hole is a black hole running backwards in time. Just as black holes swallow things irretrievably, so also do white holes spit them out. White holes cannot exist, since they violate the second law of thermodynamics

Are we in danger of black holes?

We are in absolutely no danger from black holes. They’re a bit like tigers – it’s a bad idea to stick your head in their mouth, but you’re probably not going to meet one on your way to the shops. Unlike tigers, black holes don’t hunt. They’re not roaming around space eating stars and planets

Do grey holes exist?

Could there be such a thing as a gray hole? – Quora. Simple answer, no. If a Black hole and White hole were to collide it would not create a Gray hole

A Q-star, also known as a grey hole, is a hypothetical type of a compact, heavy neutron star with an exotic state of matter.

Has NASA seen a white hole?

Is there any evidence that white holes exist? The answer is no, really. I mean, there are speculations about some weird things in the universe that might have white home signatures. There’s nothing that we can point out in the same way we can point out a black hole that says, ‘yes, this is a white hole

What is a pink hole in space?

At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. It turns out that this is only true for a few of them: most have the wrong colours to be expained by this

Why do blue holes exist?

Blue holes are formed through Karst processes and require a specific type of topography. Rocks such as limestone, gypsum and marble are soluble and dissolution creates passages and cave systems underground. This process in combination with doline formation permits blue holes to be formed

Does a red hole exist?

Using the James Webb Space Telescope (JWST), astronomers have discovered an “extremely red” supermassive black hole growing in the shadowy, early universe. The red hue of the supermassive black hole, seen as it was around 700 million years after the Big Bang, is the result of the expanding universe

Do wormholes exist?

Wormholes are consistent with the general theory of relativity, but whether they actually exist is unknown

Physicists have purportedly created the first-ever wormhole, a kind of tunnel theorized in 1935 by Albert Einstein and Nathan Rosen that leads from one place 

Can we create a black hole?But creating a black hole with even a microscopic event horizon would require billions of times more energy than the LHC is able to produce. And even if it could produce such a black hole, that object would quickly lose energy and dissipate in the blink of an eye.
