Is Andromeda older than Milky Way? And in terms of the stars present, the Andromeda galaxy’s stars are much older, and its star-formation rate is much lower: only about 20-30% that of the Milky Way. What is the age of the...
How old is the first galaxy? Observations by Hubble Space Telescope and ground-based instruments show that the first galaxies took shape as little as one billion years after the Big Bang, which probably took place about 13 billion to 14 billion...
How old is the Milky Way compared to Earth? The Earth is estimated to be 4.54 billion years old, so the Universe itself is, on average, around three times older than our Earth but only if the Universe is indeed 13.8...
Is the Milky Way larger than most galaxies? The Milky Way is only a medium sized galaxy with an estimated 200 billion stars. The largest galaxy we know of is called IC 1101 and has over 100 trillion stars. How big...
How many miles long is the Milky Way galaxy? The approximate diameter is 14.6 million miles (23.5 million kilometers) . By comparison, the Milky Way itself is roughly 100,000 light-years wide and 1,000 light-years thick. A huge disk of gas around...
How many galaxies are in the universe? If we made the most straightforward estimate using today’s best technology, we’d state there are 170 billion galaxies in our Universe. But we know more than that, and our modern estimate is even grander:...
How many stars are there in the world 2022? There are approximately 200 billion trillion stars in the universe. Or, to put it another way, 200 sextillion. That’s 200,000,000,000,000,000,000,000! How many stars does the galaxy 2022 have? The Sun belongs to...

Are there multiple suns in the Milky Way? How Many “Suns” Are in the Milky Way? Of the research conducted on our Milky Way galaxy so far, scientists have located just over 3,500 stars with planets circling around them. Each of...
How many solar system are there approximately in our galaxy? There are at least between 250 to 500 billion stars in our Milky Way galaxy, who knows how many exoplanets are truly present. There are over 700 known multi-planetary systems confirmed...
