What is the biggest star discovered so far?
The biggest star is VY canis majoris! It is believed that it is 2000 times bigger than the sun!!!!! And trust me its true
There are no stars in the world. _________________________ However, the hypergiant star S Doradus may be the brightest star so far observed. Because the center of the galaxy is sheathed in nebulous gas clouds surrounding the massive black hole in the center of the Milky Way, there isn't any way (so far!) to observe stars on the other side of our own galaxy. S Doradus is the brightest star in the Large Magellanic Cloud.
That depends on how you define "celestial body". Arguably, the largest "celestial body" thus far discovered (or ever likely to be discovered) is the universe itself. However, let's assume you mean a compact body, i.e. one which is more or less continuous (and thus excludes things like galaxies, globular clusters, and nebulae). The largest star known is VY Canis Majoris, which is roughly the size of the orbit of Saturn. The largest body in the…
The atom discovered with the highest atom number = number of proton = number of electrons Note that some negative ions might be bigger. The biggest element so far discovered is 294Uuo (Ununoctium, element 118), a superheavy transactinide element. Only a small number of atoms of this element have ever been produced. The caesium atom with an empirical radius of 260 pm.
