What is the difference between the Milky Way and the Andromeda galaxy?
The Milky Way is our home galaxy while the Andromeda galaxy is the closest spiral galaxy to the Milky Way. They both contain billions of stars, but the Andromeda galaxy is slightly larger in size compared to the Milky Way. Additionally, they are on a collision course and are expected to merge in about 4 billion years.
What is the total size of the milky way galaxy?
It is a barred spiral galaxy with a diameter of 100000 to 180000 light years, and contains 100-400 billion stars.
How big is the stars in your galaxy?
Our galaxy, the milky way, has stars much bigger than our sun. Our sun is considered one solar mass in it's size. The Milky Way has star that range from 1/2 a solar mass to 50 or 100 solar masses.
What is the NGC 613 galaxy?
The NGC 613 galaxy is a barred spiral galaxy 67 million light-years from Earth (20.7 mpc) in the Sculptor constellation, and is 100,000 light-years in diameter (same size as the Milky Way), and contains about 100 billion stars (same number of stars as the Milky Way).
Dwarf planets in the milky way?
No one knows. Astronomers are scanning the visible stars of our own Milky Way galaxy for planets orbiting faraway stars, but such planets would have to be nearly the size of Jupiter to be detected at such distances
How does the sun rank in terms of size and brightness in our galaxy?
The Sun is an average-sized star in terms of size compared to other stars in our galaxy. However, the Sun ranks as the brightest object in our Solar System since it is relatively close to Earth. In comparison to other stars in the Milky Way galaxy, there are much larger and brighter stars.
What is the PGC 2631284 galaxy?
The PGC 2631284 galaxy (one of the background galaxies in the UGC 8335 galaxy pair) is a spiral galaxy 1300 million light-years (redshift of 0.1) from Earth in the Ursa Major constellation, and is 100,000 light-years in diameter (same size as the Milky Way), and contains about 100 billion stars (the same number of stars as the Milky Way).
How many stars are the in the galaxy?
There are anywhere from 200-400 billion stars in the Milkyway. The Milky Way Galaxy comprises roughly one hundred billion stars, the closest of which is, of course, the Sun. Other notable stars include Sirius and Betelgeuse.
If the other galaxy bigger than ours or smaller?
By definition the question is incorrect. There are not only 2 galaxies in our universe, but billions. Each galaxy is a different size and is made up of millions or stars and planets. Our galaxy is called the Milky-Way, and our closest neighbouring galaxy is called the Andromeda galaxy.
What is the COSMOS 397553 galaxy?
The COSMOS 397553 galaxy (one of the galaxies in the COSMOS survey) is a barred spiral galaxy 6000 million light-years (redshift of 0.66) from Earth in the Sextans constellation, and is 100,000 light-years in diameter (same size as the Milky Way), and contains about 100 billion stars (same number of stars as the Milky Way).
What size is the Andromeda galaxy?
The Andromeda galaxy is approximately 220,000 light-years in diameter, making it significantly larger than our Milky Way galaxy. It contains around 1 trillion stars and is located about 2.5 million light-years away from Earth.
Size of Andromeda galaxy?
