How large is the Milky Way in KM?
about 1,000,000,000,000,000,000 km
The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way.
What is the diameter of the Milky Way galaxy?
105,700 light yearsMilky Way / Diameter
Is the galaxy 100000 light years in diameter?
The Milky Way galaxy has a diameter of about 100,000 light-years. The distance to Earth from the center of the Milky Way galaxy is about 30,000 light- years.
How fast is the Milky Way moving in km h?
2.1 million km/hr
And how fast is the Milky Way Galaxy moving? The speed turns out to be an astounding 1.3 million miles per hour (2.1 million km/hr)! We are moving roughly in the direction on the sky that is defined by the constellations of Leo and Virgo.
Where is the Milky Way black hole?
Carina-Sagittarius
The black hole is 5,000 light years away, located in a spiral arm of the Milky Way galaxy called Carina-Sagittarius. This observation allowed the research team to estimate that the nearest isolated black hole in relation to Earth could be only 80 light-years away.
What is the DIA of the Milky Way?
Which is the largest galaxy in the universe?
IC 1101
The biggest known galaxy, first described in a 1990 study from the journal Science (opens in new tab), is IC 1101, which stretches as wide as 4 million light-years across, according to NASA (opens in new tab). Galaxies are often bound to each other gravitationally in groups that are called galaxy clusters.
How many light-years would it take to cross the Milky Way?
The disk of our home galaxy – the Milky Way – is bigger than we previously thought. A new study shows it would take 200,000 years for a spaceship traveling at the speed of light to go across the entire galaxy.
What will happen to the Milky Way in 4 billion years?
Our galaxy is on a collision course. In roughly 4.5 billion years’ time the Milky Way will smash into the rapidly approaching Andromeda Galaxy, and astronomers are still attempting to predict what it will be like when the two galaxies collide.
How many suns are in the Milky Way?
In our own galaxy, the Milky Way, the sun is just one of about 100 to 400 billion stars that spin around Sagittarius A*, a supermassive black hole that contains as much mass as four million suns. The deeper we look into the cosmos, the more galaxies we see.
Do white holes have gravity?
Its gravity is powerful. Light cannot escape it. Hence, a black hole’s blackness. White holes are the theoretical opposite of black holes.
Is Earth bigger than the Milky Way?
Answer: Assuming a diameter for the Milky Way galaxy of about 15 kpc, which is about 4.6×10^(17) km, and a diameter for the Earth of about 12756 km, the ratio of the diameter of the Milky Way galaxy to that of the Earth is about 3.6×10^(13).
How long would it take to travel 25 000 light years?
The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is “only” 25,000 light-years away. So it would take 25,000 years to get there if you traveled at the speed of light.
What is 4 light years away from Earth?
Scientists have discovered a potentially habitable new world, a mere four light years away from Earth. They call the planet “Proxima B,” and it may feature characteristics that are just right for human life.
