How many planets are in the Milky Way 2022? “Astronomers aren’t quite sure how many planets are in the Milky Way, given we have only found a few thousand all told, but one NASA estimate suggests it’s more than 100 billion...
Are there 2 trillion galaxies? “A detailed theoretical simulation predicted far more faint, small galaxies than we’ve seen, upping the expected total to closer to 2 trillion. But recent observational evidence shows that even that estimate is far too low. Instead,...
What percent of stars in the Milky Way have planets? “Based on this, it is estimated that perhaps 20% of Sun-like stars have at least one giant planet whereas at least 40% may have planets of lower mass.” How many stars...
How much does the Milky Way weigh in solar masses? “Their answer: The galaxy weighs around 1.5 trillion solar masses. This number helps put in perspective how very small we are. Take, for instance, where stars in the Milky Way fit...
What is the mass of Milky Way galaxy? “The Milky Way’s mass of 1.5 trillion solar masses is fairly normal for a galaxy of its brightness. Astronomers used Hubble and Gaia to measure the three-dimensional movement of globular star clusters —...
What is the mass of the Milky Way? “Combined with other kinematic information about these stars, the scientists calculate that the mass of the galaxy is between 1.2 and 1.9 trillion solar masses, adding significant precision to the previous estimates.” Where...
Is anything bigger than TON 618? “No. Whatever passes the event horizon gets supercompressed and assimilated.” Is TON 618 bigger than the Milky Way? “In the case of TON 618, the enormous Lyman-alpha nebula surrounding it has the diameter of at...
How big would TON 618 be if it were a star? “TON 618 is as bright as 140 trillion suns and has a mass of about 66 billion suns. For comparison, all the stars in our galaxy combined share a mass...
Can you see TON 618 from Earth? “Due to the brilliance of the central quasar, the surrounding galaxy is outshone by it and hence is not visible from Earth.” How long would it take to travel around TON 618? “Oh, and...
How many galaxies are in the universe 2022? “This tiny patch of sky was full of galaxies, almost 10,000, of all different sizes and shapes. By multiplying this number by the number of times this tiny patch of sky would fit...
