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).
Of all known stars, the VY Canis Majoris is the largest. This red Hypergiant star, found in the constellation Canis Major, is estimated to have a radius at least 1,800 that of the Sunâs. In astronomy-speak we use the term 1,800 solar radii to refer to this particular size.Y Canis Majoris a.k.a. VY CMa is about 4,900 light years from the Earth. This value, however, is just a rough estimate because it is too far for parallax to be used.
