How big is the Milky Way galaxy in comparison to the universe?
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 many miles is Earth from the Milky Way?
The Solar System: The Solar System (and Earth) is located about 25,000 light-years to the galactic center and 25,000 light-years away from the rim. So basically, if you were to think of the Milky Way as a big record, we would be the spot that’s roughly halfway between the center and the edge.
How big space actually is?
They found that the universe is at least 250 times larger than the observable universe, or at least 7 trillion light-years across.
How big is Milky Way in light-years?
52,850 light years
Milky Way/Radius
Is the Milky Way galaxy larger than Earth?
“Our home galaxy, the Milky Way, is over a trillion times heavier than our tiny planet Earth so to escape its gravitational pull we have to launch with a speed of 550km/s [342 mi/s]. We used this…
What is the smallest star in the Milky Way galaxy?
Answer Wiki. The smallest star in the milky way is OGLE-TR-122b. Its a red dwarf in a binary star system. It is 120 times smaller than the sun, 167000 km (radius).
What is the estimated size of the Milky Way?
The new study estimates the size of the Milky Way’s disk at 200,000 light-years across. Past studies have suggested the Milky Way is between 100,000 light-years and 160,000 light-years across. (One light-year is the distance light travels in a year, about 6 trillion miles or 10 trillion kilometers.)
How many galaxies are there in Milky Way galaxy?
Our Milky Way Galaxy belongs to a galaxy cluster called the Local Group. It contains about 30 galaxies, including our near neighbors, the Andromeda Galaxy and the Magellanic Clouds, which we can see with the naked eye. Most of the galaxies are ellipticals or irregulars.
