How many Earths can the Milky Way hold?

How many Earths can the Milky Way hold?

“Plugging in our thickness and radius we get about 6.7 X 10^(51) km^3. Dividing the volume of the Milky Way by the volume of the Earth, you get (6.7 X 10^(51))/(10^12) =~ 6.7 X 10^(39) Earths that can fit in the volume of the Milky Way galaxy.”

How many suns can fit in the Milky Way galaxy?

“The Milky Way has a mass of 1.5 trillion suns.”

How big is the Milky Way galaxy compared to Earth?

“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 many Earths fit in the Milky Way black hole?

“The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. 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.”

Are there 2 trillion galaxies?

“A detailed theoretical simulation predicted far more faint, small galaxies than we’ve seen, upping the expected total to closer to 2 trillion. But recent observational evidence shows that even that estimate is far too low. Instead, there are between 6 and 20 trillion galaxies out there.”

Can a planet leave a galaxy?

“An extragalactic planet, also known as an extragalactic exoplanet or an extroplanet, is a star-bound planet or rogue planet located outside of the Milky Way Galaxy. Due to the immense distances to such worlds, they would be very hard to detect directly.”

What is the heaviest galaxy?

“Located almost a billion light-years away, IC 1101 is the single largest galaxy that has ever been found in the observable universe. Just how large is it? At its largest point, this galaxy extends about 2 million light-years from its core, and it has a mass of about 100 trillion stars.”

Is there anything bigger than Milky Way?

“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!”

Are there 100 billion planets in the Milky Way?

“Our Milky Way galaxy contains, on average, a minimum of one planet for every star, according to a new statistical study. Our Milky Way galaxy contains a minimum of 100 billion planets, according to a detailed statistical study based on the detection of three planets located outside our solar system, called exoplanets.”

What is bigger than universe?

“No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.”

How many universes are there?

“In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.”

What’s beyond the universe?

“The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.”

Could a black hole destroy Earth?

“Earth is facing no threat because no black hole is close enough to the solar system for our planet. According to NASA, even if a black hole the same mass as the sun replace the sun, Earth still would not fall in.”

Is galaxies bigger than black hole?

“And while those black holes truly are massive — weighing millions, or even billions, of solar masses — they are tiny compared with their home galaxies, reaching less than 1% of the mass of a typical galaxy and a volume a billion times smaller.”

Can galaxies have 2 black holes?

“Some galaxies, such as the galaxy 4C +37.11, appear to have two supermassive black holes at their centers, forming a binary system. If they collided, the event would create strong gravitational waves. Binary supermassive black holes are believed to be a common consequence of galactic mergers.”

Are there other Earths in the Milky Way?

“Our Milky Way galaxy is just one of the billions of galaxies in the universe. Within it, there are at least 100 billion stars, and on average, each star has at least one planet orbiting it. This means there are potentially thousands of planetary systems like our solar system within the galaxy!”

Are there 100 billion planets in the Milky Way?

“Our Milky Way galaxy contains, on average, a minimum of one planet for every star, according to a new statistical study. Our Milky Way galaxy contains a minimum of 100 billion planets, according to a detailed statistical study based on the detection of three planets located outside our solar system, called exoplanets.”

Is there anything bigger than Milky Way?

“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!”

Is the Milky Way galaxy infinite?

“Every location in the universe has its own sphere of observation beyond which it cannot see. Since our observable universe is not infinite, it has an edge.”
