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).

Are there 100 billion planets in the Milky Way?

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 galaxy is heaven in?

əˈkeɪ. ə/; Hawaiian for “open skies” or “immense heaven”) is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies….

Laniakea Supercluster
Right ascension	10h 32m
Declination	−46° 00′
Brightest member	Milky Way (mag –5.0)
Number of galaxies	100,000–150,000

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.

Is the Milky Way 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.

How many black holes are in the Milky Way?

Astronomers estimate that 100 million black holes roam among the stars in our Milky Way galaxy, but they have never conclusively identified an isolated black hole.

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!

Where does space end?

No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.

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.

Why is space infinite?

There’s a limit to how much of the universe we can see. The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).

Are there 200 billion galaxies?

All in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com.

Are there 200 billion stars in our galaxy?

Using the Milky Way as our model, we can multiply the number of stars in a typical galaxy (100 billion) by the number of galaxies in the universe (2 trillion). The answer is an absolutely astounding number. There are approximately 200 billion trillion stars in the universe.

Are there 250 billion stars in Milky Way?

The Andromeda Galaxy contains roughly one trillion stars, while the Milky Way Galaxy is estimated to contain roughly 250 billion stars.

Is the Milky Way 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.

Is ton 618 bigger than Milky Way?

In the case of TON 618, the enormous Lyman-alpha nebula surrounding it has the diameter of at least 100 kiloparsecs (320,000 light-years), twice the size of the Milky Way.

Does the Milky Way have 200 billion stars?

It’s home to over 200 billion stars with ours being the sun.” Not only is the Milky Way a huge accumulation of stars, but it holds planets, asteroids, meteors, comets and other solar remnants. Most stars are at the center of the galaxy with few at the outer edges. A supermassive black hole is at the galactic center.

Does the Milky Way have 7 billion stars?

Astronomers estimate there are about 100 thousand million stars in the Milky Way alone.
