What is the overall size of the Milky Way?

Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across. That sounds huge, and it is, at least until we start comparing it to other galaxies. Our neighboring Andromeda galaxy, for example, is some 220,000 light-years wide.

How big is the Milky Way compared to the size of the universe?

The observable Universe is 93 billion light-years, yet, our galaxy, the Milky Way, is just 100,000 light-years in diameter. It would take us endless generations just to explore our galaxy, let alone the Universe. Another ancient structure is the galaxy supercluster known as the Hyperion Supercluster.

How many suns can fit in the Milky Way?

It’s mind-boggling. The Milky Way has a mass of 1.5 trillion suns.

How many earth can fit in the Milky Way?

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.

What is the size of the Milky Way?

Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across. That sounds huge, and it is, at least until we start comparing it to other galaxies. Our neighboring Andromeda galaxy, for example, is some 220,000 light-years wide.

How big is the Milky Way compared to the 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 big is the Milky Way compared to solar system?

But what does that mean for our galaxy’s size? Simply put, our solar system is a speck compared to the Milky Way. Our Milky Way galaxy is a whopping 587 trillion light-years across. In other words, you could travel across our entire solar system 53,000 times and still not equal one trip across the Milky Way.

How wide and tall is the Milky Way?

The galaxy we live in, called the Milky Way Galaxy, is a barred spiral galaxy composed of at least 100 billion stars. It is approximately 100,000 light years across and about 1000 light years thick. It has a central bulge that is about 10,000 light years in diameter.

Is the Milky Way the largest galaxy in the universe?

Big, but not the biggest And, as I said earlier, while the Milky Way is big, it’s far from being the largest galaxy in space. Our nearest neighbour is the Andromeda Galaxy, which spans 220 000 light years. That makes it over twice as big as the Milky Way.

Is there anything bigger than Milky Way?

The reason the collision is happening a few billion years ahead of schedule is that the Andromeda Galaxy is much bigger than it appears. The galaxy’s bright, starry disk is about 120,000 light years in diameter, making it slightly larger than the Milky Way.

How many Earths can you fit in the Milky Way?

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 biggest galaxy?

The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.

Are there multiple suns in the Milky Way?

The Short Answer: Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy.

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 many Earths can fit in the universe?

By dividing the two volumes we get a factor of 3.2⋅1059, or written as decimal number: The observable comoving volume of the universe is about 320,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000-times the volume of Earth.

How large is Milky Way?

Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across. That sounds huge, and it is, at least until we start comparing it to other galaxies. Our neighboring Andromeda galaxy, for example, is some 220,000 light-years wide.

How big is Milky Way compared to other galaxies?

The Milky Way is an averagely large galaxy with a diameter of 100 000 light years and about 200 billion to 400 billion stars; but compared to larger galaxies like M100, M 87, NGC 4921 or Hercules A, the Milky Way looks like a dwarf galaxy.

How many miles is the Milky Way?
