Milky Way Galaxy
The Milky Way, named for how its pale light is seen from Earth, is the galaxy that our solar system belongs to.
954 Questions
Will the sun burn out before the Andromeda galaxy collides with our Milky way galaxy?
By the current best estimates, no. The sun will likely enter its red giant stage in about 5 billion years. The collision with the Andromeda galaxy is expected to occur in 3 to 4 billion years.
Is the earth found at the center of the milky way?
No. We are in the outer portion of the Milky way about 3/4 of the way to the edge. The center of the Milky Way could not sustain life.
How long does it take the Milky Way to rotate?
A disk has multiple speeds - at it's perfect center it's standing still (as you approach the center the speed gets smaller and smaller as you approach 0) At the outer rim (where our star Sol and it's attending planets) are rotating around the galaxy center at about 500,000 mph, ~0.0007% of the speed of light.
What is the largest object in the milky way?
Probably the furthest "named" object would be Sagittarius A a supernova remnant at about 30,000 light years.
The furthest object would be on the other side of the Galaxy at about 75,000 light years and could be a star, a nebula or just a grain of dust.
What does a milky way contains?
The Milky Way contains somewhere around 200 billion stars. These stars account for about 20% of the visible mass of the galaxy, the other 80% being interstellar gas.
However, most of the matter in our galaxy is of a form we have not yet identified, and we call it "dark matter." We don't know what it is, but we can measure its effect on the rotation rate of the stars, and we can calculate the distribution of the dark matter.
What is the Distance from the sun to the center of the milky way?
Estimated at around 25-30 thousand Light Years away
Aside from occupying space, our galaxy also rotates. It takes about 220 million years for it to spin once.
What is bigger than the milky way?
We have thoroughly explored our own planet Earth, have imaged many of the other planets from orbit, and we have no clue about any of the other planets that might be orbiting any of the TRILLION other stars in the Milky Way. Your question would be like looking closely at a single spoonful of sand in your sandbox and wondering about the biggest grain of sand on any of the world's beaches.
The biggest mountain that we know of is on Mars, Olympus Mons. We know little enough about Venus, just some radar surveys; details about the outer planets are unknown to us. We know nothing about anything outside our solar system, but it is statistically certain that taller mountains exist elsewhere in the galaxy.
How do you get a good picture of what your milky way galaxy looks like?
Technically, you cannot take a picture of our own galaxy from outside, as the camera would have to travel tens of thousands of light-years out of the galaxy to do so. However, if you're on Earth, you see a large stream of countless stars in the night sky. That is part of the milky way galaxy. The "pictures" you see in the newspapers are just artists' impressions of how the Milky Way would look, not the actually appearance.
How does the milky way galaxie appear in the night sky from earth?
It would look dark and thin on the edges, and getting oh so thicker and brighter near the center.
What is the absolute magnitude of the Milky Way?
An estimation of the absolute magnitude is −20.9.
See related question.
How big is The Milky way compared to other galaxy's?
It's respectably sized, though not the largest one we know of.
The Milky Way is the second-largest (and possibly the most massive) galaxy in the Local Cluster, but there are larger galaxies further away.
This cluster of galaxies is made up of about twenty-five galaxies including the milky way?
The galaxy cluster that contains the Milky Way is called the Local Group.
What is the name of your large galaxy nearest to your milky way?
Andromeda Galaxy is the nearest spiral galaxy to our Milky Way Galaxy. It is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 30 other smaller galaxies.
How far from the center of the galaxy is the sun positioned?
What's a sun? Joking, No the sun isn't in the middle its inside Saturn.
According to wiki:
It is extremely difficult to define the age at which the Milky Way formed, but the age of the oldest star in the Galaxy yet discovered is estimated to be about 13.2 billion years, nearly as old as the Universe itself. This estimate is based on research by a team of astronomers in 2004 using the UV-Visual Echelle Spectrograph of the Very Large Telescope to measure, for the first time, the beryllium content of two stars in globular cluster NGC 6397. From this research, the elapsed time between the rise of the first generation of stars in the entire Galaxy and the first generation of stars in the cluster was deduced to be 200 million to 300 million years. By including the estimated age of the stars in the globular cluster (13.4 ± 0.8 billion years), they estimated the age of the oldest stars in the Milky Way at 13.6 ± 0.8 billion years. Based upon this emerging science, the Galactic thin disk is estimated to have been formed between 6.5 and 10.1 billion years ago.
What does the Milky Way galaxy consist of?
There are between 200 and 400 billion stars in the Milky Way, mostly spread out in a spiral disk surrounding a dense central region. Vast clouds of gas and dust called nebulae occupy much of the space between these stars, called the interstellar medium. There may also be debris and planetary objects orbiting the stars or drifting through space. At the center, there is a bar-shaped gathering of stars and gas around 27,000 light years long called the galactic core. Around this is a disk-shaped grouping of stars and matter called the stellar disk, which stretches to about 100,000 light years across and averaging 1,000 light years thick. Our Solar System is located on one of the spiral arms making up this disk. Finally, marking the outer boundary of the galaxy is the galactic halo, which is spherical and contains older stars than the disk. It surrounds the inner galactic components at up to 200,000 light years in diameter. The entire galaxy with all its constituents is thought to orbit around a supermassive black hole found in the very center of the galactic core.
The mass of the entire Milky Way is thought to be about 600 billion times the mass of the sun, and it formed a bit over 13 billion years ago. Our solar system orbits around its center about once every 250 million years. Hypothetical dark matter is suspected of occupying most of the detectable mass in the Milky Way Galaxy. While the observable matter (stars, nebulas, etc.) is as much as 400 billion solar-masses, the total theoretical mass of the dark matter is estimated between 600 billion and 3 trillion solar-masses. The Milky Way is the galaxy we are in, along with some billions of other galaxies. There are a few hundred billion stars in our galaxy, and the Sun is a star with average brightness. There are also star clusters, and nebulas which are big clouds of luminous gas.
How far away is the Comet Galaxy from the Milky Way?
Mars (and every other planet in our solar system) is nowhere near the center of the galaxy. About 75,000 light years...
Does the Milky Way contain the local group?
No. The local group contains the Milky Way and a few other galaxies.
Where is are sun located in the milky way galaxy?
The Milky Way Galaxy is located within the Local Group of the Virgo Supercluster.

What is milky way best described as?
It is the SOLAR SYSTEM where the Earth is part of it( A Solar System Consists of Planets, Moon, Stars like SUN, Asteroids, Meteors, Comets and sometimes Black Hole).Above the surface of the Milky Way, Millions and Billions of Cluster of Stars are Scattered around it. A Cluster of Stars are made up of Looking-Young Stars but, They are actually old since the Milky Way was formed around 12 Billion Yrs. old.
How many constellation are near the milky way galaxy?
All of them. Any star you can see with the naked eye is within the Milky Way Galaxy.
