Being a semiregular variable star, VY Canis Majoris exhibits periodic light changes. Its period lasts for about 2,200 days. The French astronomer Jerome Lalande is credited to be the first person to have recorded VY CMa.
Humphreys originally estimated the radius of VY CMa at 1,800-2,100 solar radii, which made it the largest star then known. A more recent and accurate VLTI measurement gives the star a radius of 1420 Â± 120 solar radii.t has an average density of 5 to 10 mg/m 3. If placed at the center of the Solar System, VY Canis Majoris's surface would extend beyond the orbit of Jupiter, although there is still considerable variation in estimates of the radius.
