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).
Each big object in space is part of a much larger structure - the large-scale structure of the visible universe. We only see a minuscule piece of the universe. Big is bigger than we can ever imagine. VY Canis Majoris is the biggest type of star known as a red hyper giant. It is 4,892 light years from Earth and has a circumference of 5.46billion miles - around 2,000 times that of our sun. It would take a passenger jet 1,100 years to fly round it once.
