Hence, a menstrual period is the shedding of the uterus lining. The duration of a menstrual period on the average is between three to five days. As such, a period that lasts between two to seven days is considered normal. The amount of blood lost in each cycle is measured between four to twelve teaspoons.
Not surprisingly, UY Scuti is classified as a hypergiant star â which is the classification which comes after supergiant and regular giant. Its size may make it the biggest, but it is not the most massive star (where the mass in massive stands for the amount of matter in the star).
And, yet, we do not think it is the biggest! Recent observations of a star called VY Canus Majoris show that it has a size between 600 and 2100 tims the size of our Sun! However, this star is only about 500,000 times brighter than our Sun and 30 or so times more massive than our Sun.he star is 25,000 light-years away from Earth. Despite this great distance, the star would be visible to the naked eye if it were not for all the dust between it and the Earth. UPDATE! As of January 2009, we now know about some other really big stars. One is called Eta Carinae.
