What are the three largest galaxies?
The three largest members of the group are our Milky Way (second-biggest), the Andromeda galaxy (biggest) and the Triangulum Galaxy.
The other galaxies in the Local Group are dwarf galaxies, and they’re mostly clustered around the three larger galaxies..
What is the smallest galaxy in the universe?
the Milky WayThe smallest known galaxies in the Universe are actually tiny satellites of the Milky Way: objects like Segue 1 and Segue 3. They contain only a few hundred stars, orbiting their combined center of mass at less than the speed that Earth orbits the Sun: just 15 km/s.
What is our closest galaxy?
Canis Major Dwarf GalaxyThe closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
Where does Earth sit in our galaxy?
Orion ArmWe live in a seemingly nondescript neighborhood in the Milky Way galaxy, in a small spiral arm called the Orion Arm.
Will a black hole hit Earth?
There are no black holes close enough to Earth to affect us. The closest black hole to Earth that we know of is named V616 Monocerotis. It is also known as A0620-00. This black hole is 6.6 times more massive than our Sun.
How many suns can fit in a black hole?
It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths. How Do Black Holes Form?
Which is biggest galaxy or universe?
Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!
What is the biggest black hole in the universe?
And the supermassive black hole at the center of Messier 87 is so huge that astronomers could see it from 55 million light-years away. It’s 24 billion miles across and contains the same mass as 6 1/2 billion suns.
Is there a black hole near Earth?
Now, astronomers have found a “dark” black hole only 1000 light-years away from Earth—just down the road in galactic terms. It is the closest black hole to our planet ever found, in a star system that is visible to the naked eye.
What universe do we live in?
The Milky Way is in the Local Group of galaxies, which in turn is in the Laniakea Supercluster. This supercluster spans over 500 million light-years, while the Local Group spans over 10 million light-years.
What is the oldest thing in the universe?
Astronomers have confirmed the discovery of one the oldest and most distant objects ever known in the universe — a star-forming galaxy 12.8 billion light-years away that started forming within a billion years of the Big Bang that kickstarted everything.
